Please reword to avoid confusion on this point. Done. Minor issues: Section 4 says that humming should be the start of a conversation, not the end. However, it can be either. Using the document's example, the chair could ask, "Hum now if you cannot live with choice A." Silence confirms that rough consensus has been reached. There was a line hidden in there about this, but I've clarified. Section 6 tells about some pitfalls to avoid, but the hum can still be a very valuable tool to help a chair determine if the group has reached consensus. It can be (and I've added some text along these lines), but it gets misused for these purposes all too often, which is a major theme of the document. Further, a hum in a BOF is different. As I said in my reply to Ted, I've made some attempt to address this, but also pointed out the downsides. Nits: In section 2, the document says "... not appealing to some others." When I read it the firs time, the RFC 2026 definition of "appeal" jumped into my mind. That is not the intent here. Maybe it is just me. Please consider rewording, especially since the RFC 2026 meaning is used in Section 3.

Indeed, there are some shortcomings here. For the year/month/day/hour/minute/second production names I can add an explicit reference to ISO.8601.2004 Section 2.2. The zone designator is only marginally mentioned in ISO.8601.2004 Section 4.3.2. The exact date format is not reflected in Appendix B because the Appendix does not intend to capture the structure of each different property type. As the two jcardcal drafts are my first rfc documents, I am not quite sure when its a good idea to make the ABNF normative. I could probably declare it informative by virtue of the reference to ISO 8601 and RFC5545. The ABNF was added in draft 08, in alignment with the changes we've made in jcard (rfc7095). There was a lot of discussion on the jcardcal list on the date formats and it became clear that the specific variations of ISO 8601 2001 and 2004 used in iCalendar and vCard make it hard to grasp. By explicitly mentioning the date format I wanted to counteract. I'd appreciate some feedback on how to further handle this issue. Please work with your AD on this one. It's a little detail, not a big problem, but we do need to be clear about what the grammar actually is. HmmI wonder why neither RFC 5545 nor this document reference RFC 3339 instead of ISO 8601?

One overall question though: Neither the document nor the shepherd writeup explain why this document will be useful for future work. It may very well be (I'm no expert in the area), but it's at least not obvious to me that it is. You've already pulled the lever to start an IETF-wide Last Call, but before it goes to the IESG for them to work on, perhaps it would be good to say why the WG thinks this is useful as a permanent publication in the RFC series as against just a working reference document for the WG.

Some of them are right on the line between "minor issue" and "editorial" (they're editorial, but did cause some confusion for me), so I just grouped them all together here. Minor issues and nits/editorial comments: In 2.1.3, calling out any author by name is a bit weird in an IETF document, but in this case the reference is to RFC 7141, an IETF BCP. While I know Bob's a smart guy and I'm sure he contributed substantially to that document, I don't think calling out a just one author of an IETF consensus document is appropriate. (I think it's stylistically a little weird to use author names in general in IETF documents, but at least in two of the other cases, it's a single author of a non-IETF document; calling out Shreedhar and not Varghese is still weird to me, though I understand it is common practice in academic literature. If it were me, I'd reference the title, not the author. That said, you're going to have to fight it out with the RFC Editor regarding whether those URLs are "stable references".) In 2.2, second sentence: The *algorithm* isn't empty or not empty, the *queue* is empty or not empty. This had me really confused for a bit. Please fix the sentence.

I think you need to say "the dequeue function" somewhere in each sentence. In 2.2.2, your reference to using a hash as a classifier threw me. I figured out what you meant, but it was an unfamiliar concept to me. But I'm also not sure why it's useful to call out a particular kind of classifier in the first place.

Please treat these comments just like any other last call comments. For more information, please see the FAQ at <http://wiki.tools.ietf.org/area/gen/trac/wiki/GenArtfaq>. Document: draft-ietf-grow-route-leak-problem-definition-04 Reviewer: Pete Resnick Review Date: 2016-03-21 IETF LC End Date: 2016-03-28 Summary: This draft is on the right track but has open issues, described in this review. Major issues: None. Minor issues: - Figure 1, along with the discussion of it in section 3, was confusing to me. First of all, am I correct that the example displays *two* leaks? That is, there's the leak from AS3 to ISP2, and then there are the propagated leaks from ISP2 to the rest of the world. Also, "(P)" seems to be used as both a leaked prefix (from ISP1 through AS3 to ISP2 and then propagated from there) as well as what looks to be a normal prefix update between ISP1 and ISP2. Are all of the occurrences of "(P)" in Figure 1 identical? Or is the prefix update between ISP1 and ISP2 also a leak? What leaks is Figure 1 intended to show? - In 3.1: "The leak often succeeds because...". Do you really means "succeeds" and not "occurs"? If so, what does "succeeds" mean in this context? - The description in section 3.5, starting from "However", really needs a complete rewrite. It's ungrammatical to the point that I'm not really sure I understand what it is trying to say. Nits/editorial comments: - I've mentioned before that I find the "academic research paper" style a bit jarring in IETF documents. I particularly don't like the use of "we" and "us", since it's not clear whether "we" is the authors (which is how it's used in academic papers, but is inappropriate for an IETF document), the WG, the IETF, etc. Instead, I would replace all instances of "we" with "this document", or simply re-word into the passive, since a subject is rarely needed for these sentences. For example, the abstract could be rewritten as such: A systemic vulnerability of the Border Gateway Protocol routing system, known as 'route leaks', has received significant attention in recent years. Frequent incidents that result in significant disruptions to Internet routing are labeled "route leaks", but to date a common definition of the term has been lacking. This document provides a working definition of route leaks, keeping in mind the real occurrences that have received significant attention. Further, this document attempts to enumerate (though not exhaustively) different types of route leaks based on observed events on the Internet. The aim is to provide a taxonomy that covers several forms of route leaks that have been observed and are of concern to Internet user community as well as the network operator community. Please do similar edits throughout. Similarly, the referencing of authors by name seems like bad form for an IETF document. OLD This document builds on and extends earlier work in the IETF by Dickson [draft-dickson-sidr-route-leak-def][draft-dickson-sidr-route- leak-reqts]. NEW This document builds on and extends earlier work in the IETF [draft-dickson-sidr-route-leak-def][draft-dickson-sidr-route-leak- reqts]. END OLD Mauch [Mauch] observes that these are anomalies and potentially route leaks because very large ISPs such as ATT, Sprint, Verizon, and Globalcrossing do not in general buy transit services from each other. However, he also notes that there are exceptions when one very large ISP does indeed buy transit from another very large ISP, and accordingly exceptions are made in his detection algorithm for known cases.

However, it also notes that there are exceptions when one very large ISP does indeed buy transit from another very large ISP, and accordingly exceptions are made in its detection algorithm for known cases. END - Last paragraph in section 2: I'm left wondering what sorts of things that other folks might consider leaks *aren't* covered by the definition. Perhaps you want to mention that? - In 3.6, when you say "more specifics", are you using that as a noun to mean "more specific prefixes"? It's very hard to read in its current form. - Section 5 is superfluous. I'd delete it.

See [RFC6701] for details. Do you mean: In addition to any remedies available outside the IETF, the IESG may consider other actions. See [RFC6701] for details. I think that's fine, but it needn't even refer to the IESG: In addition to any remedies available outside the IETF, actions may be taken inside the IETF to address violations of IPR disclosure policies; see [RFC6701] for details. 6701 points out that actions can be taken by chairs, ADs, the IESG, or the IETF as a whole. But I'm fine with either of the above. I'm made a little nervous by the fact that RFC 6701 is Informational, and the text you have removed would give the IESG specific authority (by BCP) to impose penalties. So I think you have actually pruned too much. I would prefer that authority to be included, so maybe: I strongly disagree. Quoting 6701: This document discusses these issues and provides a suite of potential actions that can be taken within the IETF community in cases related to patents. All of these sanctions are currently available in IETF processes, and at least two instances of violation of the IPR policy have been handled using some of the sanctions listed. 6701 didn't change the sanctions available to the IETF, and this document doesn't and shouldn't either. So I disagree that this should to be added to this document. And on the specific suggestion: In addition to any remedies available outside the IETF, the IESG may, when it in good faith concludes that such a violation has occurred, impose penalties including, but not limited to, suspending the posting/participation rights of the offending individual, suspending the posting/participation rights of other individuals employed by the same company as the offending individual, amending, withdrawing or superseding the relevant IETF Documents, and publicly announcing the facts surrounding such violation, including the name of the offending individual and his or her employer or sponsor. See [RFC6701] for details. Part of what I didn't like about the -06 version was that it, like you did in the above, only pointed out the most harsh sanctions discussed in 6701, implying that those are the ones that should be used and not the others. A perfectly reasonable sanction, in some cases, is: a. A private discussion between the working group chair or area director and the individual to understand what went wrong and how it can be prevented in the future.

Document: draft-ietf-grow-route-leak-problem-definition-04 Reviewer: Pete Resnick Review Date: 2016-03-21 IETF LC End Date: 2016-03-28 Summary: This draft is on the right track but has open issues, described in this review. Major issues: None. Minor issues: * Figure 1, along with the discussion of it in section 3, was confusing to me. First of all, am I correct that the example displays two leaks? That is, there's the leak from AS3 to ISP2, and then there are the propagated leaks from ISP2 to the rest of the world. Also, "(P)" seems to be used as both a leaked prefix (from ISP1 through AS3 to ISP2 and then propagated from there) as well as what looks to be a normal prefix update between ISP1 and ISP2. Are all of the occurrences of "(P)" in Figure 1 identical? Or is the prefix update between ISP1 and ISP2 also a leak? What leaks is Figure 1 intended to show? * In 3.1: "The leak often succeeds because...". Do you really means "succeeds" and not "occurs"? If so, what does "succeeds" mean in this context? * The description in section 3.5, starting from "However", really needs a complete rewrite. It's ungrammatical to the point that I'm not really sure I understand what it is trying to say. Nits/editorial comments: * I've mentioned before that I find the "academic research paper" style a bit jarring in IETF documents. I particularly don't like the use of "we" and "us", since it's not clear whether "we" is the authors (which is how it's used in academic papers, but is inappropriate for an IETF document), the WG, the IETF, etc. Instead, I would replace all instances of "we" with "this document", or simply re-word into the passive, since a subject is rarely needed for these sentences. For example, the abstract could be rewritten as such: A systemic vulnerability of the Border Gateway Protocol routing system, known as 'route leaks', has received significant attention in recent years. Frequent incidents that result in significant disruptions to Internet routing are labeled "route leaks", but to date a common definition of the term has been lacking. This document provides a working definition of route leaks, keeping in mind the real occurrences that have received significant attention. Further, this document attempts to enumerate (though not exhaustively) different types of route leaks based on observed events on the Internet. The aim is to provide a taxonomy that covers several forms of route leaks that have been observed and are of concern to Internet user community as well as the network operator community. Please do similar edits throughout. Similarly, the referencing of authors by name seems like bad form for an IETF document.

Major issues: None Minor issues: 3.1.2 - Change "MUST" to "will" both times in the second paragraph. The last sentence of the section I don't understand; it doesn't seem to have any interoperability implications, and I don't see why the client can't examine the ticket in any way it wants.

Nits/editorial comments: 3.1.4 - Change "MAY" to "can" in the second paragraph. I'd also split that sentence into two sentences as the first half has nothing to do with the second half. 3.2.1 - The last sentence of 3.2.1 is confusing until you read 3.2.2 and 3.2.3. I would simply delete the sentence. I don't think it adds anything. 3.4 - Put the "TBD" in there so that the RFC Editor can update. 4 - Put a note to the RFC Editor here to update sections 3.1.4 and 3.4 with the error number.

Document: draft-ietf-tram-turn-mobility-03 Reviewer: Pete Resnick Review Date: 2016-09-06 IESG Telechat date: 2016-09-01 Summary: This is an odd post-telechat review, but I think the draft has gone from "Ready" to "Ready with an issue" because of an IESG Eval change. Details: I did not get to my post-Last Call GenART review of draft-ietf-tram-turn-mobility until after the telechat. Had I done so, which would have been on version -05, I would have said "Looks fine to me". However, I happened to look at the latest version, figuring I would just confirm. I found that a change was made in response to an IESG Evaluation comment from Suresh <https://mailarchive.ietf.org/arch/msg/tram/SYVAXc1dF6xUcm0OQ9xyuaknJco>: -- COMMENT: -- * Section 3.2.1 The section on sending a Refresh when the IP address does not change needs a little bit more tightening. Given that the server would reject the request with a mobility ticket in this case, it would be good to put in an explicit restriction to not add the mobility ticket in the following statement OLD: If a client wants to refresh an existing allocation and update its time-to-expiry or delete an existing allocation, it will send a Refresh Request as described in Section 7.1 of [RFC5766] NEW: If a client wants to refresh an existing allocation and update its time-to-expiry or delete an existing allocation, it MUST send a Refresh Request as described in Section 7.1 of [RFC5766] and MUST NOT include a MOBILITY-TICKET attribute. I'm not sure if the "MUST NOT" in the latter part of the sentence is correct: Since the server will reject it anyway, I don't see the harm in including the attribute that the "MUST NOT" implies, but perhaps this is belt-and-braces protocol description. On this point, I can't complain too much. However, I believe Suresh was incorrect in suggesting the first "MUST", and it should be removed. There is no harm being prevented here. "If a client wants X, it MUST send Y" is absolutely no different protocol-wise from "If a client wants X, it will send Y". The "MUST" is a misuse. I believe that this change should be undone before publication. pr -- Pete Resnick <http://www.qualcomm.com/~presnick/> Qualcomm Technologies, Inc. - +1 (858)651-4478___ Gen-art mailing list Gen-art@ietf.org https://www.ietf.org/mailman/listinfo/gen-art

I will try to explain my line of reasoning. Let me know where you disagree. If the client includes a MOBILTY-TICKET attribute in the refresh method, the refresh will fail. So, the MUST NOT is aimed at preventing the client from sending a useless packet that will be rejected anyway. "Useless" seems not a good reason for a "MUST NOT". Perhaps Tiru's explanation of "will cause an extra retransmission" is a better reason. But as I said, this isn't one that I will complain too vociferously about: What this says is "don't include the attribute; it will be rejected and you'll have to retransmit"; if you want a "MUST NOT" for that, so be it. But: The MUST stresses that the original Refresh procedure from RFC5766 needs to be used instead of the Refresh procedure with the MOBILITY-TICKET described in this one. Ah! If that's was meant, that's not what was said. It sounds like you're saying that the client *can't* refresh a request by simply sending an allocate request with the old MOBILITY-TICKET. And then I get a bit confused about the MUST NOT: The next sentence after this bit says: If the client wants to retain the existing allocation in case of IP change, it will include the MOBILITY-TICKET attribute received in the Allocate Success response. The previous sentence says that you MUST NOT include the attribute. This sentence says that you do include it. I suspect that what was intended was, "If you *just* want to refresh to retain the existing allocation in case of an IP change, you can send an allocate request including the old MOBILITY-TICKET attribute. If you need to update time-to-expiry or delete the allocation, then you *can't* just send a new allocate request with the attribute; that will get rejected. You instead *have to* use the refresh request in 5766." Do I have that right? If so, the paragraph could use a rewrite; it's not the MUST and the MUST NOT that are the problem. Anyway, I am not wedded to keeping the MUST as long as the MUST NOT prevents the sending of a packet that is certain to be rejected. Ack.

The second sentence says that you *are allowed* to include the MOBILITY-TICKET attribute in a Refresh Request if you want to retain the allocation, even though the first sentence says you MUST NOT.

A few things I found ambiguous or confusing that should be easily clarified, but nothing that should stop the document from moving forward. Major issues: None. Minor issues: 4.1.1: The figure is a bit confusing: There might not exist a "Max Slot Width at Priority 7" if bit 7 is clear in the Priority field, correct? Perhaps it would be better to just show that as "..." or "Max Slot Width at Priority n". The thing is, it might only be a single value, followed by the padding, so having the second value in there might be misleading. (Perhaps similar constructs are used in other MPLS docs and people will understand. But it took me a while to figure it out.) The discussion of Priority was very confusing for me. In the third sentence, do you mean, "A bit is set (1) corresponding to each priority represented in the sub-TLV, and clear (0) for each priority not represented in the sub-TLV"? I don't understand the MUST/MUST NOT as you had it. And I don't understand the last sentence at all. Are you trying to say, "The leftmost bit (priority level 0) MUST be set, and priority level 0 MUST be advertised in the sub-TLV."? Otherwise, I don't get it. I don't understand the MAY in the last sentence. Does that mean that I MAY also set it to the highest possible nominal central frequency supported by the link? I don't understand what that sentence is trying to tell me. Nits/editorial comments: 3, last paragraph: OLD That is, the additional information NEW That is, this section defines the additional information END As it is, it is ungrammatical. 3.1: On a DWDM link, the allocated or in-use frequency slots must not overlap with each other. I think perhaps it's clearer to simply say "frequency slots do not overlap each other", assuming that's what you mean. I don't think you're trying to say something normative there; it's just a fact. But people often read "must" (whether it's uppercased or not) to be imposing a requirement. I don't think that's what you're doing here, so better to make it clear. (As you may know, I'm not a fan of overuse of MUSTs and SHOULDs, but I do like it when documents are clear.) As an opposite example: Hence, in order to clearly show which LSPs can be supported and what frequency slots are unavailable, the available frequency ranges MUST be advertised by the routing protocol for the flexi-grid DWDM links. A set of non-overlapping available frequency ranges MUST be disseminated in order to allow efficient resource management of flexi-grid DWDM links and RSA procedures which are described in Section 4.8 of [RFC7698]. Those MUSTs look weird to me. I think instead of "MUST be" you mean "are", since it doesn't look like an implementation really has a choice here. 3.2: Hence, in order to support all possible applications and implementations the following information should be advertised for a flexi-grid DWDM link: Is that "should" in there meant to be normative? That is, do bad things happen if I don't advertise one of those items? Or do you just mean "the following information is advertised..."? 3.3: For this reason, the available frequency slot/ranges need to be advertised for a flexi-grid DWDM link instead of the specific "wavelengths" points that are sufficient for a fixed-grid link. Where you say "needs to be advertised", are you making a normative statement, or are you just describing, in which case "are advertised" would be clearer? (By the way: Typo in the following sentence. Change "thus" to "this".) 4.1: When Switching Capability and Encoding fields are set to values as stated above, the Interface Switching Capability Descriptor MUST be interpreted as in [RFC4203] with the optional inclusion of one or more Switching Capability Specific Information sub-TLVs. Same question as earlier about "MUST be" vs. "is". 4.1.1: The technology specific part of the Flexi-grid ISCD should include Same question as earlier about "should include" vs. "includes".

Hi Jari, Pete,
First of all thanks for the accurate review.
All the nits/editorial comments are correct and will be fixed.
Regarding the minor issue:
4.1.1:
The figure is a bit confusing: There might not exist a "Max Slot
Width at Priority

Perhaps it would be better to just show that as "..." or "Max Slot

(Perhaps

it was difficult to express in the figure the fact that only some of
the priorities are advertised. As you said it could be one, two or any
number up to 8.
What about a single field (with ~ on the borders to indicate that it
can have variable length) saying "Max Slot Width at Prio n" and then
say that 16 bits are used for each prio and when an odd number of
priorities is used the field is padded to line up with multiples of 32
bits?
Yes, I think that would make more sense to me.
The discussion of Priority was very confusing for me. In the third
sentence, do
you mean, "A bit is set (1) corresponding to each priority
represented in the
sub-TLV, and clear (0) for each priority not represented in the
sub-TLV"? I don't
understand the MUST/MUST NOT as you had it. And I don't understand
the
last sentence at all. Are you trying to say, "The leftmost bit
(priority level 0)
MUST be set, and priority level 0 MUST be advertised in the
sub-TLV."?
Otherwise, I don't get it.
It means that if the priority field is set to e.g. 10010010 in the
following you would find 4 fields indicating respectively: Max Slot
Width at Priority 0, Max Slot Width at Priority 3, Max Slot Width at
Priority 6 and since they are 3 a 16 bits padding to 32 bits.
OK, then I think my sentence is clearer for that: "A bit is set (1)
corresponding to each priority represented in the sub-TLV, and clear (0)
for each priority not represented in the sub-TLV."
It also means that at least one priority must be advertised (i.e.
priority is not allowed).
I get that part ("At least one priority level MUST be advertised"). It's
the end I don't understand: "that, unless overridden by local policy,
SHALL be at priority level 0." What does that mean?
I don't understand the MAY in the last sentence. Does that mean that
I MAY
also set it to the highest possible nominal central frequency
supported by the
link? I don't understand what that sentence is trying to tell me.
An example is provided in section 4.1.2, where the available range
goes from -2 to +8 but the range supported by the link goes from -9 to
+11. The sentence means that even if not available it could be
possible to indicate also n=-9 to indicate the starting point of the
range supported by the link.
" In this example, it is assumed that the lowest nominal central
frequency supported is n= -9 and the highest is n=11. Note they
cannot be used as a nominal central frequency for setting up a LSP,
but merely as the way to express the supported frequency range."
I'm ok with dropping the sentence.
I think dropping the sentence would make the most sense.
Thank you
Daniele
Thanks for considering my suggested changes.

Hi Daniele,
Thanks for addressing everything. There's only one issue left in section
4.1.1 on Priority, below. I've trimmed out all the rest.

It's the end I don't understand: "that, unless overridden by local

[DC] It means that if only one priority is supported it has to be
priority 0.
So, let me see if I have this right: It's OK to have 0110 but not
0100 or 0010? If so, why is that?
For any particular administrative purpose it could be possible to set
it to a different value, but that shouldn’t be done.
Well, it doesn't say that shouldn't be done, but it probably doesn't
need to say anything about local configurations.

If that's what you mean, let me suggest simplifying:
OLD
At least one priority
level MUST be advertised that, unless overridden by local policy,
SHALL be at priority level 0.
NEW
At least one priority
level MUST be advertised. If only one priority level is advertised,
it MUST be at priority level 0.
Thanks for the extended discussion of this. It all looks fine.

Hi Pete,
This is an “inheritance” from GMPLS, where supporting a single
priority equals not supporting priorities. If you don’t want to
support priorities you don’t want your traffic to be
preempted…hence priority 0.

For me it’s ok not to say anything on that.

That is to say, some applications/implementations will not work if you don't advertise these things, so if you're not going to advertise one or more of them, you'd better know what you're doing and understand the consequences. That's the 2119 definition of SHOULD. On the other hand, if it's really always required because you really have to support all of those applications/implementations, and there are no good reasons to fail to advertise any of these things, then that's a MUST. As I said before, I'm someone who doesn't like putting in MUSTs and SHOULDs (I've even written protocol documents where they never appear), but if you really mean "required" or "required unless you know what you're doing", I see no harm in putting them in. pr -- Pete Resnick <http://www.qualcomm.com/~presnick/> Qualcomm Technologies, Inc. - +1 (858)651-4478 ___ Gen-art mailing list Gen-art@ietf.org https://www.ietf.org/mailman/listinfo/gen-art

Reviewer: Pete Resnick Review Date: 2017-05-09 IETF LC End Date: 2017-05-14 IESG Telechat date: Not scheduled for a telechat Summary: Ready with Minor Issues/Nits To an outsider like me, this seems like a useful document and it was an interesting read. The document could use a serious edit for grammar and typos. A few specific comments below. Major issues: None. Minor issues: In section 2.1, paragraphs 4 and 5 mention "speed". The speed of what? Development of the module? It's not clear from the text. In section 3.1, it says: While there is no formal definition of what construes an SDO, a common feature is that they publish specifications along specific processes with content that reflects some sort of membership consensus. The specifications are developed for wide use among the membership or for audiences beyond that. First of all, s/construes/constitutes. But aside from that, it's not at all clear to me that a common feature is "membership consensus". For example, we don't have membership, and many other organizations use voting and not consensus. Perhaps replace the above with something simpler like: Most SDOs create specifications according to a formal process in order to produce a standard that is useful for their constituencies. Nits/editorial comments: In the Abstract and section 3.1, you use "standards-defining organization" for SDO. I've never heard that phrase used before. Elsewhere in the document, you use "standards development organization", which is the phrase I've always seen used. I suggest you change to that in both places. Throughout the document, you say things like, "the authors believe" or "we assume". This is a WG consensus document. While I generally think that using these terms is bad form in a WG document, saying "the authors believe" almost sounds like the authors believe it, but the WG might not. If the authors and the WG believe XYZ, don't say "the authors believe XYZ" or "we believe XYZ"; just say "XYZ", or at least use the passive voice. So: Section 1: OLD The intent of this document is to provide a taxonomy to simplify human communication around YANG modules. The authors acknowledge that the classification boundaries are at times blurry, but believe that this document should provide a robust starting point as the YANG community gains further experience with designing and deploying modules. To be more explicit, the authors believe that the classification criteria will change over time. NEW The intent of this document is to provide a taxonomy to simplify human communication around YANG modules. While the classification boundaries are at times blurry, this document should provide a robust starting point as the YANG community gains further experience with designing and deploying modules. To be more explicit, it is expected that the classification criteria will change over time. END Section 2: OLD For the purpose of this document we assume that both approaches (bottom-up and top-down) will be used as they both provide benefits that appeal to different groups. NEW This document considers both bottom-up and top-down approaches as they are both used and they each provide benefits that appeal to different groups. END Section 2.1: OLD For the purpose of this document we will use the term "orchestrator" to describe a system implementing such a process. NEW For the purpose of this document, the term "orchestrator" is used to describe a system implementing such a process. Section 2.2: OLD Although the [RFC7950], [RFC7950] doesn't explain the relationship of the terms '(YANG) data model' and '(YANG) module', the authors understand there is a 1:1 relationship between a data model and a YANG module, but a data model may also be expressed using a collection of YANG modules (and submodules).

This is clearly a *specification* of a path monitoring system. It gives guidances as to required, recommended, and optional parameters, and specifies how to use different protocol pieces. It is at the very least what RFC 2026 refers to as an "Applicability Statement (AS)" (see RFC 2026, sec. 3.2). It *might* be a BCP, but it is not strictly giving "common guidelines for policies and operations" (2026, sec. 5), so I don't really think that's right, and instead this should be offered for Proposed Standard. Either way, I think Informational is not correct. Importantly, I think there is a good likelihood that this document has not received the appropriate amount of review; people tend to ignore Informational "use case" documents, and there have been no Last Call comments beyond Joel's RTG Area Review. Even in IESG review, an Informational document only takes the sponsoring AD to approve; every other AD can summarily ignore the document, or even ballot ABSTAIN, and the document will still be published (though that does not normally happen).

We may have to invest some more time and text then. I personally don't object to "informational" as an aim, but if that means removing major parts of the content, I'd be rather unhappy. Thanks for considering this. IMO, I don't see why doing this as PS would require removing anything; lots of PSs have informational content in them. Pete, also Alvaro gave us a routing AD review on Friday, 16. June (and he had comments). Bruno's shephard review as part of the WG Last Call resulted in better structuring and definitions in the document. So far, no AD or reviewer "tends to ignore [this] Informational "use case" document".

I'm not sure what to do about that; perhaps register it here and make the reference both 5640 and this document. However, when someone goes to update 5640 some day, they're going to have to put into the IANA considerations to update both the OSPF and BGP registries. I'm not sure how to keep track of that. Perhaps saying that this document "Updates: 5640"? That doesn't seem great either.

I don't understand what the intent was there - whether it was a mistake or was trying to express something that I am missing. I believe it was entirely intentional. The first instance allows to add new trace header fields (which should be kept together in groups), the second allows adding other types of header fields. Correct, that was the intention. In 5322, optional-field is a catchall for any new header field, so you need one for new trace fields and one for other fields. Otherwise, there's no way to put a new field between two trace fields. This was a fix in 5322 from 2822. This really needs some further discussion. (E.g., should the valid values for as used with trace be distinct from those in its later appearance? Yes. It would have been better to have 2 separate productions, like trace-optional-field and other-optional-field, but what Pete did seems to be Ok. Yes, that might have been nice, but putting extensibility syntax throughout the grammar starts to get ugly. (Imagine resent-optional-field, originator-optional-field, etc.) I think just one is fine. This needs to be thrashed out with mail experts before this fix is finalized. I don't know what forum is appropriate for that. I am not sure. Pete? Probably ietf-822, but (a) I personally haven't read the list in a very long time, and (b) I don't think there's anything terribly controversial about the change. Ignoring that, I agree this change to 5536 would achieve the goal without requiring a change in 5322, which is progress.

t with the mentioning of accessibility in the first paragraph of the same section. Conformance with local accessibility laws and regulations may not be identical with actual accessibility. This simply says that IASA should take that into account. 7. Section 3.2.3 - the second bullet seems to be redundant with the last bullet in section 3.1 (Mandatory Criteria). In any case, this 'need' seems to be mandatory, not only 'important'. I tend to agree, particularly if 3.1 is rewritten as you suggest. Unless someone sees a subtlety both of us are missing, that can probably be deleted. 8. Section 4: 'It is anticipated that those roles will evolve. The IASA is responsible for keeping the community informed in this regard, and MAY do so without updating this memo.' I would be a little concerned if some of the key roles would change without this document being updated. I understand the need to be flexible, but we need to put some limits. Maybe at least emphasize the need to inform the community by a MUST. For example: 'It is anticipated that those roles will evolve. The IASA MUST keep the community informed in this regard, and MAY do so without updating this memo.' I don't think the MUST significantly changes the meaning, so I'm ambivalent about the change. Since this text was put in to address a comment in AD Evaluation, I'm inclined to hear from Alissa. 9. Section 4.3 - be clear that by 'Secretariat' what is meant is 'IETF Secretariat'. Yes, I believe the first occurrence of "Secretariat" moved in an edit, thereby dropping the "IETF". It probably wouldn't hurt to put "IETF" in front of all of them. 10. Two statements about the responsibility on setting the meetings dates seem to be contradictory or at least confusing: in section 4.4: 'It (DR - the IAOC) approves the IETF meetings calendar.' in section 5.1: 'The IASA selects regions, cities and dates for meetings' 4.4 is the approval. 5.1 is the selection. I don't think that's a problem. Perhaps change "approves" to "gives final approval of"? But I'm not sure that's necessary. Is really the IASA responsible with setting or proposing dates? I thought that the calendar is set years in advance taking into account different criteria (avoiding conflicts with other SDOs calendars, avoiding major holidays, etc.) Ah, so you're saying that the dates are first researched by the Secretariat. Is that true? If so, it could be clarified. 11. I am not sure that it is clear what is meant by 'travel risks' in 5.2 and 5.4. In any case, wherever we are talking about sharing with the community information about 'travel risks' we need also to mention if there are any exceptions from the Important Criteria detailed in Section 3.2 I always read "travel risks" as identical with the "economic, health, and safety risks" mentioned in 3.2.1. Do you think we should change the text? Nits/editorial comments: 1. In Section 1, expand SSID Sure, pending your above comment on section 1. 2. In Section 2: 'We meet to pursue the IETF’s mission [RFC3935]' - RFC 3935 is also BCP 95, the other BCPs are indicated by both BCP and RFC numbers, this should be the same 3. also in Section 2: s/Meeting attendees need unfiltered access to the general Internet and our corporate networks./Meeting attendees need unfiltered access to the general Internet and their corporate networks. 4. also in Section 2: "Bar BOF" can be referred by RFC 6771 (also include in Informational References) 5. section 3.2.3 - unless there is a special reason I suggest to delete the double-dashes before and after -- or at an acceptable -- 6.

The only "issue" I have here might end up being an editorial issue, but I list it as a Minor issue because it might be substantive. Major issues: None. Minor issues: In the paragraph after Figure 3, it says, "and subsequent values are monotonically increasing". I'm not sure I understand what that means. If 0 is the highest priority, then 1 is a *lower* priority than 0, not an increasing priority. If you are trying to say that the numeric value of the priority field is increasing by 1 for each subsequent value, then "monotonically increasing" is wrong; the sequence "0 2 5 36" is monotonically increasing. You'd say instead, "and subsequent values increase by one". If all you mean is that values start at 0 and go up from there, I think you should just delete the entire phrase; it doesn't add anything and strikes me as confusing. Nits/editorial comments: Why are RFC 4086, RFC 8018, and ietf-ippm-metric-registry Informative References instead of Normative? The uses appear to be normative. I'm not clear why the examples were split between Section 6 and Appendix A; seems like you could just use the long one in section 6 and explain only the important bits. I also note that neither of them make any claims about normativity: That is, most examples in documents I see always say something like, "If there is a conflict between anything here and the syntax in the model, the model wins." Is that not the case in these sorts of model documents? Pet peeve: Except in Acknowledgements, I really don't like the use of "we" in IETF documents (even though it's becoming more and more common). It's not clear to whom it refers (the WG? the authors? the IETF?). In most places, it can be replaced with "This document", or using passive voice (e.g., s/We define X as/X is defined as). There are only 4 occurrences: Abstract, 1.1, 3, and 3.1. Easy enough to change. Note to shepherd: In the shepherding writeup, question 1 is not answered correctly. This document is going for *Proposed* Standard, not *Internet* Standard. Further, there is no explanation for why this should be a standards track document (though I believe the answer is pretty straightforward). You should go correct that. While you're at it, you can update answer 15, as that nit was corrected. ___ Gen-art mailing list Gen-art@ietf.org https://www.ietf.org/mailman/listinfo/gen-art

of copy editing.
Major issues:
None.
Minor issues:
I don't think there are any issues here. However, some of the things I've got

which MUST be identical (Unless you mean something really weird that I don't

something else? I just had a bit of trouble understanding what you meant.

Yes, sorry about that. Section 3.1 has a similar problem:

That's not quite right. You are giving a list of fields (as you say,
"Primary configuration fields include:"), so you don't want something in
that list that is a rule. The field is "the test session name", and that
field MUST be identical to the client name.
When you say, "the test session name that MUST be identical with...", it
sounds like there is more than one test session name, and you're talking
about the one that MUST be identical with the client name. Similarly
with the above, it sounds like there's one test session name which
uniquely identifies it, and one that doesn't uniquely identify it.

Document: draft-ietf-extra-imap-objectid-03
Reviewer: Pete Resnick
Review Date: 2018-07-14
IETF LC End Date: 2018-07-13
IESG Telechat date: Not scheduled for a telechat
Summary:
I've got a few concerns about the document, but it is almost ready. I hope
these can be addressed easily. (Also, my apologies for being a day late, though
hopefully not a dollar short. I also apologize for being a GenART reviewer who
happens to know the topic area, but hasn't been following the WG; you would
have had an easier time with someone else. ;-) )
Major issues:
§4 ¶2
I don't believe this ought to be a SHOULD. While the document explains that
this allows for disaster recovery, I don't understand what sort of disaster
would allow the server to preserve UIDVALIDITY and name, yet not be able to
preserve MAILBOXID. If you're talking about things like re-building a crashed
disk, that doesn't justify downgrading the MUST: Even though 5321 says that the
server MUST take responsibility for the message after delivering the 200, if
lightning strikes immediately after writing the message to disk and scrapes
just those sectors, that's not something that an implementer SHOULD anticipate.
This sort of softening also has the horrible side-effect (as do many other
things in IMAP) of not allowing a client to properly depend on the feature: If
a server is permitted, for whatever reasons it believes are really strongly
justified, reset MAILBOXIDs, clients will have to keep using name +
UIDVALIDITY, even if the capability is advertised. That's bogus.
Please either explain the justification for this SHOULD better, or simply
change it to a MUST and remove the bit about disaster recovery.
§4 ¶5
Why would this be allowed? If you can't preserve MAILBOXID across RENAMEs,
there's no point in advertising this capability.
§5.1 ¶2
See above on §4 ¶2.
Minor issues:
§5.1 ¶3&4
I think you need to add an explanation here that there is no way to use
MAILBOXID with a STORE command or other similar ones, and there never will be a
way (unless you really want to be able to all occurrences of a message across
all mailboxes). Maybe this goes in §9.
§8.2 ¶2
Why isn't it advisable (or even RECOMMENDED) that *all* object identifiers (not
just MAILBOXID) be globally unique? Seems like the recommendation applies to
all of them.
In the example, it is plausible that an OBJECTID proxy could rewrite
identifiers to avoid conflicts (e.g., append "-from-servername" to each
identifier). So I think it would be clearer to say:
OLD
the backends will not use the same identifiers for different objects
NEW
different objects never use the same identifiers, even if backend system
have identifiers that collide
§8.3
I'm not clear on the SHOULDs in this section. These seem like perfectly good
operational guidance statements, but not interoperability requirements. I say
lowercase them.
Nits/editorial comments:
§1 ¶3
s/If a mailbox is successfully renamed, the client knows/If a mailbox is
successfully renamed by a client, that client will know
§5
No need for the sentence at the top of this section. Just go right to 5.1.
§5.2 ¶5
The sentence is ungrammatical ("to in all")

In particular, *most* of the MAYs are just goofy and wrong, and many of the SHOULDs shouldn't be there. When you're putting in a 2119 keyword, they should point out a place where an implementer needs to look to make sure they get their implementation correct. A lot of these aren't helpful in that regard. A few examples: In 8.2: In addition to the set of EID-Prefixes defined for each ETR that MAY register, That's not a protocol option being described. (such as those indicating whether the message is authoritative and how returned Locators SHOULD be treated) That's not a piece of implementation advice. In 8.3: This MAY occur if a Map Request is received for a configured aggregate EID-Prefix for which no more- specific EID-Prefix exists; If "MAY" can be replaced with "might or might not", you probably want "may" or "can". Unless also acting as a Map-Resolver, a Map-Server SHOULD never receive Map-Replies; That's a statement of fact, not an implementation instruction. Please go through and get rid of the bogus ones. If it's not an indication of an implementation option (or lack thereof), it shouldn't be 2119ed. ___ Gen-art mailing list Gen-art@ietf.org https://www.ietf.org/mailman/listinfo/gen-art

[Gen-art] Preliminary Qs for Genart review of draft-ietf-detnet-use-cases
Hi Lou, I've got a preliminary question about draft-ietf-detnet-use-cases that isn't answered in the intro to the document or in your shepherd writeup. I've Cced the WG just to make sure they're in the loop, and I've Cced the gen-art list and the responsible AD just in case Deborah or any of my Genart colleagues wish to say, "Pete, stop worrying your pretty little head and go finish your Genart review!" And I swear, I'm not asking this just to delay having to read 79 pages. (OK, maybe a little.) What's the motivation behind publishing this document? From the intro, it looks like it's purpose was to document the use cases so that the WG could do its work. Is there a reason that it needs to be published for posterity? Will people in the future need to reference this document? It would help me to review the document if I understood why it is being published instead of simply being a tool that the WG used and now no longer needs. I promise, in the meanwhile I'll continue to read the document and get the rest of my review finished, but I'd like to understand more about the purpose of the document.

I think the document serves a number of purposes: - It has been the document that has been guiding the scope of the solutions being worked in the WG this is the one that I think you are keying off of. - It also serves a long lived purpose to help those learning / new-to detnet, to understand the types of applications that can be supported by DetNet. Again this is about DetNet scope, but learning about it in the future rather defining it now. - The final value I think about (I'm sure others have their own list) is that it allows those WG contributors who are users ensure that their concerns are addressed by the WG. For them, this document covers both their contribution and provides a long term reference to the problems they expect to be served by the technology, both in the short term deliverables and as the technology evolves in the future. If you think the Shepherd write up needs to say more, I'm very open to suggestions. Actually, better than just saying these things in the shepherd writeup, I think it's worth saying in the intro of the document. I'll make sure that's in my editorial comments in the review.

I reviewed the diff with 4583. The changes were easily understandable and the improvements were obvious. Well done. No major issues at all. I think section 13 isn't as clear as it ought to be, but not a showstopper. A couple of nits noted. Major issues: None. Minor issues: 13: I found this section confusing. You could just explain this interactively with IANA, as I suspect they will find it confusing too, but I'd suggest: - Where you need to have IANA do something new, identify that to IANA as "IANA is requested to register...", replacing "This document defines" in 13.6. - For the remainder, identify those with "IANA has registered...", replacing "This document defined" in 13.2 through 13.5. You can put a parenthetical note next to each one that says, "No new IANA action requested here" This all gets cleaned up by the RFC Editor anyway, but the whole idea of the IANA Considerations is to make it clear what IANA needs to do, not format the section for what it should look like when published. Finally, I don't see a need for the "contact i...@ietf.org" bit. This is going to be a standards track document, and that is always the case for standards track documents. Nits/editorial comments: 5.1: - Table 1 contains "c-s", but it has not yet been explained.

Major issues: In 3.1: I get worried when I see this: SID/Label: If length is set to 3, then the 20 rightmost bits represent a label. So, the Length is not a length, but rather a flag. This seems like it has the potential for an interop problem. If a general implementation treats it as a length, it's going to get the left-most 24 bits when the value is 3. Even if the implementation chooses the right-most 24 bits, it's only supposed to take the right-most 20 bits and mask off the extra 4 bits. Or are you going to specify that implementations must always set the extra 4 bits to 0? Maybe this sort of thing is the way things have always been done for TLVs, and if so feel free to ignore me, but from an code implementation perspective, this seems like an accident waiting to happen. (Known sometimes as a "foot-gun".) Minor issues: In 4.4: The SRMS Preference TLV MAY only be advertised once in the OSPFv3 Router Information Opaque LSA and has the following format: You mean MUST, not MAY there. In 7.1 and 7.2: If SID/Index/Label is a label, is it using the low 20 bits of the first 3 bytes of the field (i.e., bits 4-23)? Is there a requirement that the high 4 bits and the low 8 bits must be cleared by the implementation? Some clarification would be useful. In 8.1: You talk about setting the IA-flag, but this version of the document doesn't define the IA-flag anymore. Is it defined elsewhere? Nits/editorial comments: In 3.1: Ignoring the issue stated above, I also found this text a bit confusing: Length: Variable, 3 or 4 octets Obviously you mean that the value of Length is either 3 or 4. At first I read it as the value of Length was variable, and that it took up 3 or 4 octets in the Sub-TLV. If this is the way you've always written these things, fine, but it seems to me it would be clearer to say. Length: Either 3 or 4 In 5: s/we need a single advertisement/a single advertisement is needed Just being pedantic. If you like it, use it.

The document editor notes that similar sorts of things have been done in previous OSPF document without problems, but they still make me nervous. Thanks to the editor for quickly addressing all of the issues in my previous review. Major/minor issues: In 3.1: Length: Either 3 or 4 octets SID/Label: If length is set to 3, then the 20 rightmost bits represent a label. If length is set to 4, then the value represents a 32-bit SID. This sort of mechanism worries me. The Length is not a length, but rather a flag. This means you can't have a general parsing implementation, as it would treat the field as a length and get the left-most 24 bits when the value is 3. Even if the implementation chooses the right-most 24 bits, it's only supposed to take the right-most 20 bits and mask off the extra 4 bits, which are not required to be zeroed. I understand that similar things have been done before without problems, but this seems like an implementation accident waiting to happen. In 7.1 and 7.2: When the V-flag is set (making SID/Index/Label is a label), the value is in the low 20 bits of the first 3 bytes of the field (i.e., bits 4-23). As with the comment regarding 3.1, this seems like it has the potential for implementation problems. You could explicitly say to mask of bits 0-3 and 24-31 (since there is no requirement for producing implementations to clear those bits) and shift the value 8 bits to the right, but this just seems like a bad way to design this. That said, I again understand that similar things have been done before without problems.

[...] Historically Internet standards have generally been concerned with the technical specifications for hardware and software required for computer communication across interconnected networks. However, since the Internet itself is composed of networks operated by a great variety of organizations, with diverse goals and rules, good user service requires that the operators and administrators of the Internet follow some common guidelines for policies and operations. That sounds like what this document is doing. It also sounds like this document is unlike to advance to Internet Standard, as there's not the kind of iterative implementation that protocols go through. It's not a big deal either way, but this does seem better suited to a BCP. Nits/editorial comments: Abstract: s/draft/document/g Introduction: "Many Service Providers (SPs) who...". You don't use "SP" anywhere else in the document, and other places where you use the phrase it isn't capitalized.

Agreed. I've entered these as RFC Editor notes. Fixed. Section 7 recommends that all IMAP clients be modified to display a clear error when the server advertises UTF8=ONLY. What's the expected behavior of existing, unmodified clients? Such clients will not be using the UTF8 parameter to SELECT/EXAMINE (mailbox opening) commands, so they will fail to do anything useful. But this is to be expected. No change. Nits/editorial comments: Section 2 ought to introduce what's being added to the protocol. Adaptations of the first two sentences in Section 10 (IANA Considerations) would suffice. Done. While not strictly a security consideration, it would be useful for section 11 to point out the potential for user confusion caused by SEARCH command match strings that have different UTF-8 representations but display identically or similarly (strings that look like they should match don't).

Re: [Gen-art] Gen-ART review of draft-gellens-mime-bucket-bis-05.txt
this section. It says
that IANA has already added "codecs" and "profiles" as optional
parameters the media types... but honestly, I haven't found evidence
of it. Can you please point to what IANA has already done?
Additionally, I noticed in the I-D tracker that IANA has added this
draft as references to a selection of media types. Is this what was
requested by this draft? Honestly, I think not. I suspect this is
totally different from what this draft is requesting.
Nits:
- Section 3.1, at the top of page 8, the word "REQUIRES" is
capitalized. Since this is not an RFC 2119 word, I would suggest to
write it in lower case.
An element MAY include an octet that [RFC2045] REQUIRES to be
encoded.
- Section 3.1, same paragraph as the previous comment, towards the
end. For the sake of clarity, I would suggest to refer to "percent
encoded", which I believe is the common terminology for special
characters that are encoded with a percent symbol. That would make the
text:
and single quote characters have special meaning and
so MUST themselves be percent encoded.
^^^
This comment also applies to the last paragraph in Section 4.2.
- I don't understand why Sections 3 and 4 have different structure.
They should be equal in structure. For example, take the BNF
definitions. We have Section 3.2 titled "Generic Syntax", while
Section 4.2 is not a BNF. Ok, it is Section 4.5, but why is it titled
"Profiles Parameter BNF definition"? I agree more with the latter
title, but should also be applied to the codec BNF definition.

If that doesn't fall within the 2nd paragraph of RFC 2026 section 5, I don't know what does. Just to be disagreeable... I think "requirements for the operation and administration of a type of device" puts it squarely into the "Applicability Statement" range, in part of permit testing of those requirements and advancement along the standards track. Of course, the precedent is RFCs 1122 and 1123 which requirements for operation and administration as well as for protocol conformance and are clearly applicability statements (and more or less the prototype for that category). Just to be somewhat agreeable... ;-) Normally, I would be right with you and say, "This should be on the standards track." However, this document is about CGNs. It's about things that are almost by definition not nice interoperable players on the Internet. They are messy local devices for (albeit large) local networks. Indeed, there are many folks who think that horrific plagues be visited upon those who deploy CGNs and that they should be dismantled as soon as humanly possible, if not before. But in any event, this is not really a spec "for hardware and software required for computer communication across interconnected networks", but rather is a document for "networks operated by a great variety of organizations, with diverse goals and rules" to provide "operators and administrators of the Internet follow some common guidelines for policies and operations". Or at least I think a strong case can be made for that. I think that's why several other behave documents ended up being BCPs. I could make an argument for standards track, but I think BCP is a reasonable alternative conclusion to come to as well for this particular document. pr -- Pete Resnick<http://www.qualcomm.com/~presnick/> Qualcomm Incorporated - Direct phone: (858)651-4478, Fax: (858)651-1102 ___ Gen-art mailing list Gen-art@ietf.org https://www.ietf.org/mailman/listinfo/gen-art

d add a forward pointer to mptcp in 8.3 as another mechanism (in addition to BGP) to deal with the problem. My suspicion is that section 7.3 underestimates the availability (current and future) of multipath transport. Apple is using it now in production, and Linux already has it in their implementation. I think this is actually a reasonable possible solution in the future, and I would be a little more optimistic than the WG in this section. I've added "(even if new releases of operating systems get multipath protocols support there will be a long tail of legacy hosts)." to clarify my lack of optimism.. You can have the half empty glass; I'll take the half full one. ;-) Nits/editorial comments: Two editorial bits in section 1: This document defines routing requirements for enterprise multihoming using provider-assigned IPv6 addresses. We have made no attempt to write these requirements in a manner that is agnostic to potential solutions. Instead, this document focuses on the following general class of solutions. Is that second sentence right? If you are giving a general class of solutions, that seems agnostic to the particular solution. Just a bit confusing. Updated.

Hi Jen, Thanks for the additional updates. A few comments inline. On 3 Jul 2019, at 20:07, Jen Linkova wrote: Again, hosts pick default addresses for applications to use, and applications pick the addresses that packets will use. OK, I guess we are just using different terminology here... For me 'a host' is a whole element connected to the network, including all subsystems and applications running. Until your email I was thinking about an application as an element of a host. If I got you right, when the draft says 'host' you read it as 'network stack on a host', right? Well, yes, to a certain extent. But my point here was a bit different: Even if we call it "the network stack on a host", it isn't picking the addresses that packets will use, at least not on a packet-by-packet basis. That gets back to the point about dynamic updates: Even if the host stack were to change its mind about which the correct address is, that host isn't using that new address for packets unless/until currently running apps shut down their existing connections and make new ones. They're using the old address until doing so actually fails, and then only if they reinitiate communications. The "stack" can't change that, it can only suggest to the upper layers that they stop using what they're currently using. (You've talked about this in the new paragraph in 6.) How about this? : "It should be noted that [RFC6724] only defines the behavior of IPv6 hosts to select default addresses that applications and upper-layer protocols can use. Applications and upper-layer protocols can make their own choices on selecting source addresses. The mechanism proposed in this document attempts to..." I've updated that paragraph: "It should be noted that [RFC6724] only defines the behavior of IPv6 hosts to select default addresses that applications and upper-layer protocols can use. Applications and upper-layer protocols can make their own choices on selecting source addresses. The mechanism proposed in this document attempts to ensure that the subset of source addresses available for applications and upper-layer protocols is selected with the up-to-date network state in mind. The rest of the document discusses various aspects of the default source address selection defined in [RFC6724], calling it for the sake of brevity "the source address selection". I hope that the last sentence makes the rest of the document less confusing. What do you think? Yes, that'll be OK. I'd also suggest taking a look through the rest of section 6 for use of the word "host" and see if the word "default" needs to be inserted somewhere after it (like "...hosts to choose the correct *default* source address"), or if it needs to be changed to "application". I've updated a number of places as well. There are still quite a few places that I would change in section 6, but I'll leave it to Alissa to decide which (if any) are really worth diving into. I think now you understand what I'm trying to get at. Nice. If it were me, I'd add a forward pointer to mptcp in 8.3 as another mechanism (in addition to BGP) to deal with the problem. It is there: https://tools.ietf.org/html/draft-ietf-rtgwg-enterprise-pa-multihoming-11#section-8.3 Sorry, I wasn't clear: I meant it would be nice if there reference in 6.7.1 to section 8.3, or a mention in 6.7.1 of MPTCP in addition to its mention of BGP. My suspicion is that section 7.3 underestimates the availability (current and future) of multipath transport. You can have the half empty glass; I'll take the half full one. ;-) As per Magnus's suggestion, I've updated the text to mention that PA-based multihoming and MP transport could benefit from each other: https://tools.ietf.org/html/draft-ietf-rtgwg-enterprise-pa-multihoming-11#section-8.3 Fair enough.

That seems to me to be stylistic - I'm not at all sure what makes "(1)" more readable than "one". I'm making the change, but I can't begin to fathom how it improves the document. Yes, it is completely stylistic and I'm sorry I was not more explicit about that earlier: It was mostly that it was inconsistent (sometimes using the digit in parens, sometimes using the word), but in at least one instance I read "set to one" too quickly and parsed it as "set to one of" something or other. Just using the digit as you had in your second message is perfectly fine. Section 3 is in an odd place. I'd say either move it up to the top, or put it down in section 7. Moved to section 1. Yeah, that's fine. Again, just a stylistic thing. 4.2 mentions virtual reassembly. Virtual reassembly applies to 4.1, 4.3, and 4.4 as well. Perhaps moving the discussion of virtual reassembly up to the top of 4 would make more sense. I think you're inferring the applications to 4.1, 4.3, and 4.4. 4.1, for example, makes rather a point that in the absence of virtual reassembly the router will make different routing decision. (I could say "incorrect", but the issue is that it is in fact making a correct decision in what could be argued to be the wrong context). I'll see what I can do with this, but I'm going to have to ask you to look at the diff and see whether you agree with the change. Yeah, that's exactly what I was thinking of. I like the new 3.1, though I would change "It can be useful in" to "It could be useful to address the problems in". That is, it doesn't really address those problems, because you couldn't really use it in those contexts. In 4.5, insert "duplicate IDs resulting in" after prevent. It took me a bit to figure out what this was referring to. Also, change "are not easily reproducible" to "do not occur as frequently"; I think it reads better. Ack And just to yell into the wind: Section 7.3 seemed a little wimpy to me, but I can't for the life of me figure out how to make it any stronger or more likely to be listened to. End of pointless yelling. Ron started out with "let's just deprecate Internet Layer Fragmentation entirely." Good luck, great way to create an RFC that will be completely ignored.

Regarding an overview statement, how about changing OLD TEXT the set of Rules is browsed to identify which Rule will be used to compress the packet header. The Rule is selected by matching the Fields Descriptions to the packet header. The detailed steps are the following: NEW TEXT the general idea is to find in the Rule set a Rule that has a matching Field Descriptor (given the DI and FP) for exactly each and every header field of the packet being compressed. The detailed algorithm is the following: I would use "all and only those header fields that appear in the packet" instead of "each and every header field of the packet". The phrase "each and every" is so idiomatic in English that I think the native English speakers might misread it. But otherwise I think this is fine. Section 7.5.2: This encoding seems to use more space than needed. I assume you kept the size in multiples of 4 to make it on nibble boundaries, but I don't understand why you'd want 28 bits instead of 24. The larger sizes could simply be 0xFF followed by the 16-bit value. [DB] I don't quite understand his proposal. Is it a two-sized approach (4 bits and 24 bits), or a three-sized approach (4, 12 and 24 bits). In the former case, we pay a high cost for value sizes 15 and upward. In the latter case, the intermediate size (12 bits) is only applicable to value size 15 (or 15-31?). I like the three-sized approach and suggest we don't change our current spec. We expect the 4 and 12 bits encodings to be used most of the time, and added the 24 bits encoding as a safety net. Three sizes is fine, but I thought that you should have: - 0 to 14 : 4 bits - 15 to 254 : 12 bits, 0b followed by the value in 8 bits - 255 to 65535 : 24 bits, 0xff followed by the value in 16 bits Why do you need the 4 extra bits? 8.2.4: "The W field is optional" - Is OPTIONAL not appropriate here? If so, this appears in many places in section 8. DB: True. I haven't paid enough attention to the use of capital OPTIONAL, overall. I will give it another pass.

That said, the IPR declaration for this document still shows, "Licensing Declaration to be Provided Later"; perhaps everybody is fine with RAND for this case. The extension in this draft requires signaling and coordination between multiple routers; the dynamic nature of agreeing on which router is the GDR is what requires interoperability between the different routers. This type of load balancing can be useful wherever multiple PIM DRs exist, so I don’t think it can be considered a private extension, or applicable only in single-vendor deployments.

Hi Randy, We probably at some core level disagree about whether "informational text that explains how it is expected to be used" is in-and-of-itself "normative"; I think in IETF documents, that's really all that it means. But that might be moot: If the NENA document is going to be updated to describe the how clients and servers are to use the tag, why not simply remove sections 3 & 4 from this document and put in a reference to the NENA document as "Work In Progress"? If the IETF is not defining how the tag is going to be used, then point to the document that will. In its current state, the document reads like protocol to me and therefore worthy of standards track. If you truly want simply a registration, make the reference and it will be a perfectly reasonable Informational document. pr On 8 Mar 2020, at 15:22, Randall Gellens wrote: Hi Pete, The document adds a tag.

Looks to me like it is complaining about long lines once unwrapped. Nothing to fix here AFAICT. 1. It'd be good to state the reasons why this document updates 3864 earlier than in §6.1. [1] recommends using the intro section for that. Given that 3864 and 4021 are purely about IANA considerations, it seemed silly to call them out in the Abstract or Section 1 since they are not of technical import to the document. 2. Any reason for using the .test TLD rather than .example? RFC2606 says: ".test" is recommended for use in testing of current or new DNS related code. ".example" is recommended for use in documentation or as examples. [1] https://authors.ietf.org/required-content, Introduction checklist Two reasons: First, we needed enough easily distinguishable example addresses and using only .example and example. seemed like it would be too easily confused visually. But second, we were having problems keeping the examples to 72 characters for the text versions of the document. Using .test seemed the safest way to address the problem given that 2606 reserves it. Any downside you can see in using it?

I only noted those that caused me confusion or seemed useless. All of these are either minor issues or nits. Either way, the document is generally ready. Major issues: None. Minor issues (or might be nits): In 2.3: The validity interval of this trust anchor SHOULD reflect the anticipated period of stability... Are there cases where it wouldn't reflect the period of stability? If so, it would be good to give an example. If not, then s/SHOULD reflect/reflects. Similarly for: Thus, the entity that issues the trust anchor SHOULD issue a subordinate CA certificate that contains... In this case, that SHOULD might even be a MUST. In section 4, in the last full paragraph and the bullets, I'm not at all clear why these are RECOMMENDEDs and SHOULD [NOT]s. If they're not MUSTs, it seems like you should explain circumstances (at least in general terms) where an implementation would choose to do deviate from these. Nits/editorial comments: In the introduction, the "SHOULD" seems superfluous; it doesn't indicate some important implementation advice that someone wouldn't otherwise notice in the protocol. But it's a nit if ever there was one. ___ Gen-art mailing list Gen-art@ietf.org https://www.ietf.org/mailman/listinfo/gen-art

For more information, please see the FAQ at <https://trac.ietf.org/trac/gen/wiki/GenArtfaq>. Document: draft-ietf-rtgwg-enterprise-pa-multihoming-08 Reviewer: Pete Resnick Review Date: 2019-06-04 IETF LC End Date: 2019-06-04 IESG Telechat date: Not scheduled for a telechat Summary: Almost Ready. I found this overall to be an excellent document with clear technical explanations that even an upper-layer knucklehead like me could understand. However, there a couple of issues could use more discussion. I put them as "Minor issues", in that they're not showstoppers, but I do think they're important and hope you'll be able to address them. Major issues: None. Minor issues: Throughout, but particularly in section 5, this document refers to "hosts" doing address selection. To be fair, so does RFC 6724, but 6724 is referring to *default* address selection. In reality, *applications* do address selection on a host; the host stack will only do address selection if the application requests a default address. That works well for the scenarios in 6724, but in this document, for example section 5.2.3, I'm not so sure. The idea that a host would receive an ICMP destination unreachable and re-arrange its address selection seems at least an incomplete picture: An application with a (normal, non-multi-path) TCP connection to a remote application is not able to "try another source address to reach the destination"; the source address is already set for that TCP connection, so the only choice is to close the connection entirely. If the application chooses to re-establish the connection with a default address, yes, the host stack could then give a new default address back to the application, but this is hardly the dynamic and quickly adjusting process that the document seems to be envisioning. I don't think the above invalidates the core of the document or requires some grand rewrite. But I do think some clarification is in order, saying that the mechanisms described help with the *default* address selection, and some short discussion of the limitations for what applications can (and more importantly cannot) do with these mechanisms would be useful. My suspicion is that section 7.3 underestimates the availability (current and future) of multipath transport. Apple is using it now in production, and Linux already has it in their implementation. I think this is actually a reasonable possible solution in the future, and I would be a little more optimistic than the WG in this section. Nits/editorial comments: Two editorial bits in section 1: This document defines routing requirements for enterprise multihoming using provider-assigned IPv6 addresses. We have made no attempt to write these requirements in a manner that is agnostic to potential solutions. Instead, this document focuses on the following general class of solutions. Is that second sentence right? If you are giving a general class of solutions, that seems agnostic to the particular solution. Just a bit confusing. A host SHOULD be able respond dynamically... Do you mean "is expected to" instead of "SHOULD"? "SHOULD" seems overdone. ___ Gen-art mailing list Gen-art@ietf.org https://www.ietf.org/mailman/listinfo/gen-art

Major issues: None Minor issues: None Nits/editorial comments: In Section 2.1 and 2.2, Instead of "set to one" and "set to zero", it would read easier with "set to (1)" and "set to (0)", or some similar construction. Section 3 is in an odd place. I'd say either move it up to the top, or put it down in section 7. 4.2 mentions virtual reassembly. Virtual reassembly applies to 4.1, 4.3, and 4.4 as well. Perhaps moving the discussion of virtual reassembly up to the top of 4 would make more sense. In 4.5, insert "duplicate IDs resulting in" after prevent. It took me a bit to figure out what this was referring to. Also, change "are not easily reproducible" to "do not occur as frequently"; I think it reads better. And just to yell into the wind: Section 7.3 seemed a little wimpy to me, but I can't for the life of me figure out how to make it any stronger or more likely to be listened to.

My apologies for this very late review. I hope these comments are useful, but none of these are showstoppers in my opinion. Major issues: None. Minor issues: Section 5: If the SCHC Packet is to be fragmented, the optional SCHC Fragmentation MAY be applied to the SCHC Packet. Don't you mean: If the SCHC Packet is to be fragmented, the OPTIONAL SCHC Fragmentation is applied to the SCHC Packet. or even just: SCHC Fragmentation is applied if the SCHC Packet is to be fragmented. I think it's confusing to say that using SCHC is optional if the SCHC Packet is to be fragmented. If you're fragmenting, it's not optional, is it? Section 7.1 or 7.3: It took me a while to get that what you're looking for is a Rule in the list of Rules that has a function for *all* of the header fields given the DI and FP. It would be good to say some sort of overview thing like this explicitly, either in 7.1 or at the top of 7.3. It's possible this is obvious to someone versed in this topic, but it wasn't for me. Section 7.3: Question: Is it possible for multiple Rules to match a given packet? What happens if you find more than one? That should probably be specified. Section 7.5.2: This encoding seems to use more space than needed. I assume you kept the size in multiples of 4 to make it on nibble boundaries, but I don't understand why you'd want 28 bits instead of 24. The larger sizes could simply be 0xFF followed by the 16-bit value. Nits/editorial comments: Section 7.3: In the last bullet of the Rule selection algorithm, it says: Sending an uncompressed header may require SCHC F/R. Sending a compressed header may also require F/R, couldn't it? Seems to me this sentence is superfluous. Section 8.1, second paragraph: It seems like you'd want one or both occurrences of "optional" to be "OPTIONAL", in the 2119 sense. Is there a reason they're not? I'm not sure I understand the last sentence of that paragraph. Do you simply mean, "You can ignore the rest of section 8"? That seems unnecessary to say. Section 8.2.2.2: Change: o their numbers MUST increase from 0 upward, from the start of the SCHC Packet to its end. to: o their numbers MUST increase by 1 from 0 upward, from the start of the SCHC Packet to its end. in order to avoid someone being inordinately cute (or stupid). 8.2.4: "The W field is optional" - Is OPTIONAL not appropriate here? If so, this appears in many places in section 8. ___ Gen-art mailing list Gen-art@ietf.org https://www.ietf.org/mailman/listinfo/gen-art

However, there are some things in the document which could use clarification or editing. Major issues: The first paragraph of section 8 really has too little useful comment. There is no reference for 802.1ak, the reference to 802.1Q is inline instead of in the references section, and the content of neither of these standards is explained in this document. The paragraph doesn't really lay out what the topic of discussion is, at least for someone like myself who is not versed in the topic. I really think this needs to be addressed. Minor issues: (Some of these issues are more or less "minor".) Section 3.1.4 seems a little thin to this non-expert. It is certainly true that "every station has to be configured to wake up to receive the multicast", but it seems like only a poorly designed protocol would create the situation where "the received packet may ultimately be discarded" on any kind of regular basis. If there are a class of packets that the receiver will ultimately discard, that sounds like they should be on a separate multicast address, or the sender should be determining if the packet will be discarded before sending it. Perhaps what this section is driving at is that multicast protocols are often designed without taking power-saving considerations into account, but then *that's* what this section should probably talk about. As it is, it sounds like the old joke about saying to the doctor, "My arm hurts when I do this" and the doctor replying, "The stop doing that". In section 3.2.1, the last paragraph is missing a bunch of information: "It's often the first service that operators drop": What is "it"? "Multicast snooping" is not defined. In what scenario are devices "registering"? Section 3.2.2: "This intensifies the impact of multicast messages that are associated to the mobility of a node." I don't understand why. Are you simply saying that as the number of addresses goes up, more discovery packets must be sent? Section 3.2.4: This seems like more of general problem than a multicast-specific one, and as described it sounds like an attack rather than a poor outcome of a protocol design decision like the rest of the examples. Perhaps framing it that way would make the section clearer. Section 4.4: Which problem in section 3 is 4.4 supposed to address? Section 5.1: "...and sometimes the daemons just seem to stop, requiring a restart of the daemon and causing disruption." What a strange thing to say. Does this simply mean "and the current implementations are buggy"? Also section 5.1: "The distribution of users on wireless networks / subnets changes from one IETF meeting to the next". This document doesn't seem to be about the IETF meeting network. This sentence seems inappropriately specific. The "NAT" and "Stateful firewalls" sections are also overly specific to the IETF meeting network. Generalizing would help. 7: This section seems quite thin, and perhaps unnecessary. The recommendations are implicit in the previous sections. Nits/editorial comments: Section 3.2.4: The mention of the face-to-face (probably better: "plenary") meeting seems unnecessary. Section 5.1: Numbering the subsections would probably be useful. ___ Gen-art mailing list Gen-art@ietf.org https://www.ietf.org/mailman/listinfo/gen-art

Major issues: None. Minor issues: In 5.1, the SHOULDs regarding the default hash masks seem a bit odd: Usually SHOULD means that bad things are likely to happen if you choose otherwise, but if you know what you are doing, you might choose something different. Is there any real harm to choosing some other hash masks, or are you simply saying that these are perfectly reasonable? Not a big deal one way or the other, but if there is harm, you should probably say something about that. In 5.1: "The hash value computed will be the ordinal number of the GDR Candidate that is acting as GDR." I'm not sure what that sentence means, but then again, this entire document is way outside my area of expertise, so perhaps this is obvious. Nits/editorial comments: The IDNITS tool reports: == There are 4 instances of lines with non-RFC6890-compliant IPv4 addresses in the document. If these are example addresses, they should be changed. == There are 1 instance of lines with non-RFC3849-compliant IPv6 addresses in the document. If these are example addresses, they should be changed. Are those the addresses in 5.2.1? Are they kosher? In 5.3.2, why is it "RECOMMENDED that the addresses are sorted in descending order."? Is that what's mentioned in 5.4? If so, perhaps a forward reference would be helpful. Finally, my "interesting note": I see in the shepherd report: (7) Has each author confirmed that any and all appropriate IPR disclosures required for full conformance with the provisions of BCP 78 and BCP 79 have already been filed. If not, explain why. Yes, there is IPR and it has been declared with #1713. (8) Has an IPR disclosure been filed that references this document? If so, summarize any WG discussion and conclusion regarding the IPR disclosures. Yes, IPR has been declared and the WG has been notified. That seems to indicate that nobody had any comment about the IPR declaration. But I also see noted in the shepherd report, "Cisco has an implementation of this protocol. No other vendors have indicated plan to implement the specification". That leads to a pretty obvious question: Are other vendors not implementing this because of the IPR (which you'd think would be a concern), or are other vendors planning on implementing this in the future, or is this just a Cisco-private extension that requires no interoperability? It seems curious that there was no discussion at all. ___ Gen-art mailing list Gen-art@ietf.org https://www.ietf.org/mailman/listinfo/gen-art
