Interesting... that could be the case. Have we even tried to identify and advertise those architectural principles since the early days? It may no longer be achievable, as pressure from vendors for new features and functionality drives new protocols and protocol additions, and while saying no sounds good in theory, the reality is that it probably doesn't really prevent the efforts, as much as cause them to be done as via private vendor=specific efforts... What's necessary, I think, is to respond to pressure for new features and functionality differently. Rather than saying yes or no, say we have noticed that the existing architecture fails to meet needs X, Y, and Z; and we propose to change the architecture in such a way to accommodate those needs while still safeguarding other important features or interests Keith, having been one of the progenitors and the editor of RFC 1958, I hear what you're saying. On the other hand, I have observed with horror the whole clean slate Internet exercise of the last few years. I am not optimistic that we could ever reach consensus. In fact I have been pessimistic about this for years (ever since RFC 2775 in fact). It's rather like trying to design a new global architecture for the road system. Brian there have indeed been many proposals which diverged in all directions, so I can understand the horror feeling about some of them (which, I am afraid, reflects that we have not been doing that well in architecture education). I am optimistic, however, that a right new architecture will emerge. I am not sure whether the road system analogy fits well since we build info highway, not physical highway. Did the old telco system look like the road system many years back? Internet as a different global infrastructure has largely subsumed it, isn't it? Lixia

Re: History of protocol discussion or process in WG
got several quick replies! a few points: 1/ there seem 2 separable issues: - whether AB's suggestion is something worth considering doing - whether one believes it is feasible to do it. Lets not mix the two. 2/ there seems an implicit assumption that, if a history record is written, it'd only document one view (hence all the concerns about not being able to agree)? Maybe it is best to document different opinions if different opinions exist? Some time down the road IETF can look back, not only see which opinion has a better match to the reality (or even none of them), but also (hopefully!) understand better where our thought has gone right/wrong. 3/ no question that doing this would take time and effort, just like anything else that is worth doing. So the real question is: would this be worth trying?

Even getting consensus on a summary of where you ended up is quite tricky. Because of who I'm responding to I'm imagining getting consensus on a summary of where the RRG ended up on the discussion of well whatever it is that they were discussing regarding id/loc split and all that stuff. WGs aren't particularly easier in this regard. You could probably get consensus on which set of documents a WG published in most cases, but if you added any context, say a discussion about whether those documents are still good ideas, it becomes a lot harder. This has value. I've supported certain aspects of the ISD proposals, of some things coming out of newtrk, etc. One aspect I've always disagreed with is proposals of this type that proposed to be generally applicable across the IETF. I agree that writing down where we were, where we are, what happened in between can be valuable. However it is quite expensive, and we need to balance that.

Re: voting system for future venues?
top posting to make a small point: for the many IETF meetings I've gone to over the years, reserving hotel room took less than 10min in general. For this Taipei meeting however, because the primary hotel price is way above US federal allowance (that's how my employer reimburses me), and the only overflow host is about equally pricy, for the first time I have to find lodging myself--this has taken me hours and still not settled yet (even with a local helper from Taiwan).

For example: http://www.ietf.org/mail-archive/web/renum/current/msg00060.html This appears to be due to MHonArc's use of the PRE tag, which tells the web browser to display the literal text exactly as given, in a fixed-width font. The MHonArc FAQ suggests a couple of solutions to this problem: Can long lines be wrapped in converted messages? http://www.mhonarc.org/MHonArc/doc/faq/mime.html#lineclip Can the PRE tags be removed from converted messages? http://www.mhonarc.org/MHonArc/doc/faq/mime.html#removepre Can we consider using either of these options? Using maxwidth=xxx would solve this problem, though of course it opens the debate about what's the right value for xxx. Using nonfixed has the nice property of letting the web browser wrap the text to the window width, but might break ASCII-art diagrams. Perhaps that could be fixed by making the default font a fixed-width one (e.g. via style sheet) and using the keepspace option, which would give us monospaced text while still allowing the web browser to wrap the text to the current window width.

We (the MIT crew at the time) did various trials of NETBLT after the RFC998's publication, and collected a list of issues for further investigation. For example, one issue I can still recall clearly is NETBLT's congestion control design and the interaction with TCP traffic (I cannot recall the whole list on top of my head now after all these years, though there may still be old notes around).

A number of us have been developing a set of recommendations designed to adapt the Nomcom process to better match current realities of the IETF community.

They can be adopted immediately, possibly by the current Nomcom, should it so choose. Others require a formal development and approval cycle.

Please feel free to discuss the proposal with any of the authors or folks listed in the Acknowledgments section, or on this list. I read the summary version of it: seems to me a timely effort in improving our process. it'd be great if we could do this for next nomcom:) One comment, then one new suggestion for you to consider. The comment: I support the idea of having a second 'expertise' pool of volunteers, but I wonder where comes this suggestion of selecting *3* members from this pool. A few random questions: - Do we know what is this number for the last several NOMCOMs? - Assuming ISOC keeps the records of NOMCOM volunteers over time: what percentage of volunteers that would fall into this second pool? - Did this number 3 come from a rough expectation on how many NOMCOM members should have this direct involvement in the process of IETF leadership (IAB/IESG/WG chair)? e.g. say you expect total 5 people with experience, you pick 3 from 2nd pool first, then expect 2 more from the bigger pool ... Personally I feel (1) there should be a expected low threshold of NOMCOM member with this direct IETF leadership experience, and (2)this threshold should be higher than 3. Now the suggestion: Since some of the suggested enhancements would require modifications to 3777, I'd like to bring up another thought I've had for a long time: the current NOMCOM eligibility requirement (3 of the last 5 IETF meetings) seems a bit low, I feel that a longer experience with IETF process than 2 years (as minimum) requirement could help NOMCOM's decision process, as IETF is already over 24 years old now with a pretty long and rich history.

As I recall, Joel actually ran some of these kinds of numbers. I don't remember the details he produced, but they were part of our consideration and we definitely all haggled quite a bit about the number to recommend. If Joel already got the numbers, it seems useful to know. What about my other question, what percentage of volunteers over the last few years that would fall into this second pool? This would help understand the feasibility of the idea (i.e. the 2nd pool still needs to be large enough) There was a remarkable amount of support for 3, bordering on unanimity. (Exercise to the reader: take a guess who was the odd one out...) The reason for preferring 3 was balancing a desire to ensure a /minimum/ level of knowledge but also to limit the amouont of /dominance/ of old-timers. So the feeling was that two was not enough to meet the minimum, but requiring four would start feeling like dominance among the voting members. four is still less than half of voting members, not dominance? Take into account the fact that many people probably do not attend all IETF meetings, as a strawman for a longer IETF experience, what about attending 5 of the last 8 or 10 meetings? Speaking only for myself, I'll say that it's quite easy to go to many IETF meetings, but never learn anything about IETF process. the above statement applies in general, independent from the NOMCOM eligibility criteria. When someone has the responsibility for choosing the people who manage the process, we ought to focus on ensuring that level of knowledge. Hence the second pool. and I support the second pool idea I've been on 3 Nomcoms. Some of the folk who did not know much IETF process were nonetheless very strong contributors. Some weren't. The key argument for retaining this less experienced criterion is that it tends to add some fresh perspective (along with the naivete... so it's a mixed benefit.) - definitely people can all be strong contributors, with or without much IETF knowledge. - I think an effective NOMCOM does require some minimal IETF knowledge from its members. - fresh blood is always important.

Re: Comment on draft-iab-ipv6-nat-00
Christian, I want to say thank you for the comments! In fact I wondered whether people noticed this draft as there had been no comment till this msg showed up. On Mar 18, 2009, at 9:44 AM, Christian Vogt wrote: Lixia, David, and all - I think it is very useful that IAB is taking position on the issue of NAT in IPv6. And it is great that you, Lixia and David, have documented this position. Below I have one comment on the document. I admit that the comment is a bit hypothetical, but I do believe it is worthwhile to be considered in the discussion around IPv6 NAT. On page 9, you state, based on a citation from RFC 4924: We believe that providing end-to-end transparency [...] is key to the success of the Internet. I think this statement needs elaboration. Let me first quote the RFC4924 text here so people can see the context of this discussion: As [RFC4924] states: A network that does not filter or transform the data that it carries may be said to be transparent or oblivious to the content of packets. Networks that provide oblivious transport enable the deployment of new services without requiring changes to the core. It is this flexibility that is perhaps both the Internet's most essential characteristic as well as one of the most important contributors to its success. To me this essentially stated that network, please let users data go end-to-end and stay intact End-to-end transparency is not a reason for the success of the Internet. Instead, it is a requirement that follows from the overloading of identification and location semantics onto IP addresses: It is exactly those applications that pursue this overloading, in form of address referrals, which have difficulties with the lack of end-to-end transparency. I believe that people in general agree that applications should not use IP address for referrals. As RFC1958 Architectural Principles of the Internet (June 1996) stated: 4.1 Avoid any design that requires addresses to be hard coded or stored on non-volatile storage (except of course where this is an essential requirement as in a name server or configuration server). In general, user applications should use names rather than addresses. Maybe it's too late so my brain got foggy, however between these two issues, (1) keeping user packets intact as they transit through the network, and (2) applications using address for referral I do not see that (2) is a consequence of (1), as you seem to believe. Since the comments below seem trying to justify for IPv6 NAT, I would also like to point out the following text in draft-iab-ipv6-nat-00: If we accept the view that some, but not all, parties want IPv6 NAT, then the real debate should not be on what benefits IPv6 NAT may bring. As every coin has two sides, it is undeniable that network address translation can bring certain benefits to its users. However the real challenge we should address is how to design IPv6 NAT in such a way that it can hide its impact within some localized scope. If IPv6 NAT design can achieve this goal, then the Internet as a whole can strive for (re-installing) the end-to-end reachability model. The draft did not take any position on 1:1 NAT; it simply stresses the importance to strive for (re-installing) Internet's end-to-end reachability model, if/when one designs IPv6 NAT. And I believe you too agree with this. Lixia (no hat on) Of course, this is not to mean that NAT, as used in IPv4 today, would be a harmless technology if we had a clean identifier-locator separation. But this is because IPv4 NAT does more potentially harmful things apart from removing end-to-end transparency. The reason for the harmfulness of IPv4 NAT is not the address rewriting by itself; it is that IPv4 NATs multiplex multiple internal addresses onto a single external address. This address overloading is causing problems that wouldn't go away even if we had a clean identifier-locator separation -- problems in terms of reduced host reachability, reduced network robustness, and a limitation to connection types with en-route-modifiable port numbers. The reason why address overloading causes these problems is that it (a) makes addresses ambiguous and, for the purpose of disambiguation, (b) adds per-connection state to the network. Now, assuming we had a large enough number of addresses for a one-to- one mapping between the internal and external addresses of a NAT, the NAT could do simple address rewriting without address overloading, hence avoiding aforementioned problems. If we further assume that we had a clean identifier-locator separation, then why would it matter that simple address rewriting causes a loss of end-to-end transparency? Why would it matter if a locator changes en route for a packet if both the old and the new locator map unambiguously to the same identifier? I

Once we have established a session then how the packets are labeled for network layer purposes doesn't matter much (modulo security) but how do we get communications set up in the first place? Suppose I want to reach foo. Who do I ask to find a locator for him? Split DNS works fine when there are just two states, inside and outside -- a DNS server can be configured to know how to respond in each case.

Re: Daily Dose version 2 launched
Hi Henrik, here is my 2 cents: every time when I go to tools page is because I'm looking for some tools, but not news. Assuming others go there for the same purpose, then one main goal is to ease the tool searching, right? instead of daily dose being the front page, what about treating the daily dose just as an item (that's a tool in some sense:), and make the content of http://tools.ietf.org/tools/ the front page? for me that can be a speedup Lixia Hi Joel, On 2007-11-02 18:00 Joel M. Halpern said the following: I second John's note. When I saw Pasi's note, I had assumed that he was referring to a link off of the tools page. Replacing the tools page with an activity summary is quite surprising. Joel Hmm. I'm not sure exactly what's the issue here, so let's try to explore this and see what we can find out. Essentially, the change is two-fold: 1. The old lefthand list of links have been replaced by the same lefthand list of links which appear on all the WG and other tools pages, making for one less list of links to keep up-to-date manually. This has been in the works for quite some time; I've tried to poll people on it, and most people seem to be happier with the lefthand menu on the WG pages than the front page menu. 2. Replacing the static text on the first page with a news item page. The static text that was replaced was as follows: -- - Welcome to the IETF Tools Pages These pages are maintained by the IETF Tools Team. The aim of these web-pages is to help the IETF community as follows: * Make it easy to find existing tools * Provide means of feedback on existing and new tools (wiki and mailing list) * Provide information on new and updated tools If you have comments on these pages, or ideas for new tools or for refinement of current tools, please send them to tools- [EMAIL PROTECTED] For current tools, there may also be a page in the IETF tools wiki (in addition to the tools page you can reach through the menu to the left) which summarises proposals and known deficiencies - feel welcome to check this out, and contribute your information! -- - The way I see it, replacing that with a news summary would be a good idea. The text above was appropriate when the tools pages were being established; they are now used by a lot of people, and the text above seems to be a bit superfluous. I could be wrong about that, and if so, an indication of how you feel about the old and new page would be good. Some options are: - You would specifically like to keep the text above (or some modification of it). - You agree that it's time for a re-working of the front page, but you don't want to have the latest happenings on the front page, you want them as a separate news page. - You don't care too much what's at the front page, as long as it's not too heavy-weight -- the major objection isn't to the news page as such, but to the increased size of the page *for you personally as a consumer of the page* - Some other option which I haven't understood the importance of yet, which you will be able to formulate better than I can here :-) Please speak up and indicate as specifically as you can what's good and bad about the change, and how we can improve it; and we'll try to make it so!

However as Jari already pointed out, whatever label one puts on a prefix may not correspond to what is done with it, *especially* as time goes. (a motto I heard from my high school son, the only thing that does change in life is change :-) and I would not attempt to bundle opinions regarding UCL-C and PI (I saw Ted already showed an example). Furthermore, we are all in this continuing process of understanding their implications in this complex, exciting, and constantly changing Internet. The people that are fighting having ULA-C are the same ones that don't want PI, and they are trying to force ULA-C == PI so they can turn that argument around and say 'we told you PI was a bad idea' when there is no way to filter out what would have been ULA-C. If you really believe there is going to be a routing system problem, then you absolutely have to support ULA-C because it is the only way to enforce keeping private space private.

The question on the table (and also part of 6man charter) is whether we need an additional type of ULAs, one that is centrally allocated. Such addresses might be useful for a couple of reasons. One reason is that we could guarantee uniqueness, which might be important, e.g., for a company that is running a lot of small company networks as a business, and wants to ensure the address spaces do not collide. But another, more important stated reason was that we should have a way give people address space that is different from PI in the sense that those addresses are not recommended to be placed in the global routing table. Arguments against such address space relate to the following issues: - The costs for any centrally allocated space are likely going to be the same, so what is the incentive for the customers to allocate ULA-C instead of PI? - There is no routing economy that would push back on advertising more than the necessary prefixes, so what is the incentive that keeps the ULA-C out of the global routing table as years go by? (When the companies that allocated ULA-C grow, merge, need to talk with other companies, etc.) The end result of our discussions was that we clearly do not have agreement on the way forward, and we settled for writing a draft about the issues instead. That is still in the works.

Re: on the value of running code (was Re: Do you want to have more meetings outside US ?)
.. I think we've seen several examples of where the IETF has spent significant amount of energy, ranging from heated discussions to specification work, on solutions that simply won't fly. It would be useful if that energy waste could be reduced. Having 'running code' as a barrier for serious consideration within the IETF may be one approach. I agree that running code should be given extra weight, but I am not sure that running code should be a requirement for something which is not well understood yet (some Lemonade WG documents come to mind). forgive me for jumping into the middle of a discussion (and I did not know which of the lemonade doc's the above referred to), but my past experience seems suggesting that an attempt to implement a not well understood idea is a good way towards a better understanding of how to make the idea work, or what can be potential issues. IMHO, running code gets more credit than is warranted. While it is certainly useful as both proof of concept and proof of implementability, mere existence of running code says nothing about the quality of the design, its security, scalability, breadth of applicability, and so forth. running code was perhaps sufficient in ARPAnet days when there were only a few hundred hosts and a few thousand users of the network. It's not sufficient for global mission critical infrastructure. it seems to me the above argues that running code is necessary, but not sufficient as evidence of a sound design. (well, that is the interpretation; I have not seen anywhere a claim that running code is sufficient, but rather simply to filter out the weed) Lixia ___ Ietf mailing list Ietf@ietf.org https://www1.ietf.org/mailman/listinfo/ietf

Whiteboard sounds good idea to me, but maybe new undesirable things come with it (variable RTT per user is one). As Joel mentioned below, wb was in use for a few years back in early/ mid 90's. In addition to IETF we used it extensively in research discussions among remote collaborators. Variable RTT did not seem to be an noticeable issue. Back when things were being multicast with vic and vat we used wb as well though as far as I recall it was used almost eclusively by the remote participants (though that does predate the significant use of wireless at the IETF). the display device at the meeting location might be the issue. Sitting in the office individual can use his/her desktop/laptop to draw/type/input PS files to the wb, but the meeting room needs a big size display that everyone can see (this was before the day of projectors).

I missed Ohta Son's original post, thanks to Valdis for catching this incorrect statement. IP packets can flow anytime. If/when deployed, the existence of an RSVP reservation is expected to improve the delivery quality of those IP packets, and the lack or breakdown of that reservation simply leaves the packets with their regular best effort delivery. It is just a minor engineering decision to allow optional circuit switched service over a best-effort-capable network. 1) I wasn't aware that RSVP caused packets to be routed according to a flow ID contained in the packet rather than the IP address in the packet. 2) If an intermediate router handling an RSVP connection decides to die an interesting death, packets can still be sent (assuming things like multihoming and BGP convergence) and successfully arrive before a new RSVP setup completes. It doesn't sound like a circuit-switching scheme, it sounds like a resource reservation scheme to guarantee sufficient bandwidth. -- Valdis Kletnieks Computer Systems Senior Engineer Virginia Tech

Hmm, wonder if QOS here might imply different things ... Put aside the history where it came from, MPLS finally did find a need for it: as the Internet topology gets more and more richly connected, there is a need to spread out traffic over all existing connectivities in some controlled way. There is the adm-control and BW reservation side of QOS, but in case of MPLS, it also helps with the above issue. Note I am not saying MPLS is the right solution for the problem. To me the right solution to the above mentioned problem should be a multi-path routing protocol. My 2 cents (and stop, don¹t mean to join another round of MPLS bashing) Lixia
