the following document:
- 'Experiences from Cross-Area Work at the IETF'
  draft-arkko-iesg-crossarea-02.txt as Informational RFC

Hi Jari,

Thanks for your draft.
A couple of points.

1.

   Cross-area work does present some challenges, however.  Apart from
   the advisor model there are no established practices and the
   processes and division of responsibility differs from case to case
   [RFC2026  http://tools.ietf.org/html/rfc2026].

Regarding there are no established practices, I would stress the 
directorate process. Not really processes in the sense of RFC 2026, but 
pretty useful for cross area work.


For example, for MIB doctors, see 
http://www.ietf.org/iesg/directorate/mib-doctors.html


   All MIB documents will be passed by a MIB doctor reviewer before
   they will be approved by the IESG. The MIB doctor review must be
   done after the Working Group Last Call and before the IETF Last
   Call. ADs and WG chairs responsible on I-Ds that include MIB
   documents should ask the OPS ADs for a MIB review as soon as the
   document completed WGLC.

For example, for the YANG doctors, see 
http://www.ietf.org/iesg/directorate/yang-doctors.html


   All YANG documents will be passed by a YANG doctor reviewer before
   they will be approved by the IESG. The YANG doctor review must be
   done after the Working Group Last Call and before the IETF Last
   Call. ADs and WG chairs responsible on I-Ds that include YANG
   documents should ask the OPS ADs for a review as soon as the
   document completed WGLC.

For example, the performance metrics directorate, see 
http://www.ietf.org/iesg/directorate/performance-metrics.html
Note that this directorate is a relatively new directorate, so the 
process is still debated


Etc... I can tell you that that IPFIX doctors is about to be put in place.

As an OPS AD, I'm trying to make sure that the OPS-related directorates 
have a clear documentation containing: the directorate goal, the 
process, the benefits, the guidelines, etc...

2.

  part of the problem here is
  that IESG does not normally develop a master plan, but rather
  individual documents and charter proposals are brought to the IESG
  in a piecemeal fashion, one by one.  This makes it hard to see
  bigger trends and possibilities for colliding work.

I'm not sure if the master plan is the primary problem. At the time of 
the charter creation, discussions regarding the work division between 
different WGs take place. However, along the time, different WGs take 
different directions. And there, the master plan might fall apart. So I 
would say the problem is the lack of revisiting the existing charters/WG 
new directions on regular basis.

Somehow, my comment relates to a sentence I see later in the draft:

  Periodic review and re-assessment is healthy and encouraged.


3.
Jari, you mentioned in one of the emails: The document has been mostly 
aimed at ADs and WG chairs
Out of the 10 recommendations, some don't give me a clear advice. I can 
only say: sure, that is common sense!


   7.   The best examples of successful cross-area work involve
combining two pieces of expertise, with both parties having an
incentive to complete the work.

4.
Potentially, out of the 10 recommendations, you could flag the ones that 
might require some sort of process improvements.

For example:

   10.  In general, the ability to associate work with all the areas
that it relates to will be helpful not just for scheduling, but
also for participants following an area of work, review teams,
and so on.

Musing on draft-resnick-on-consensus-01

2013-02-14 Thread SM

Hi Pete,

I was musing on draft-resnick-on-consensus-01.  In the Section 1:

 We don't require full consensus; that would allow a single
  intransigent person who simply keeps saying No!  to stop
  the process cold.  We only require rough consensus: If the
  chair of a working group determines that a technical issue
  brought forward by an objector has been truly considered by
  the working group ...

The above is about working group consensus.  I suggest adding some 
text in the Introduction Section which mentions that it is about 
that.  The We only require rough consensus can be misunderstood as 
being the bar in an IETF-wide call.


 Participants ask, Why are we bothering with this 'humming'
  thing?  Wouldn't a show of hands be easier?

The IAB recently had a discussion about bottom-up organizational 
modes.  If I am not mistaken (please correct me) the IETF is the 
only organization that uses humming.  I would say that it works in 
the IETF as it is part of the culture; it cannot be grafted on an 
organization.  There are cases when a show of hands can be used.  The 
sentence that follows the quoted text explains when to use humming.


In Section 2:

  The key is to separate those choices that are simply unappealing
   from those that are truly problematic.

I leave it to you to see whether you want to use the following:

   Any attempt to determine consensus is difficult if the issues 
are technical,
economic and political. Impassioned discussion, with little 
technical content,
leads to an impass. It is up to the chair to tease apart the 
points and find

out how to reduce the amount people disagree on. Find the bounds of the
conversation. Separate out the technical issues.

Credits to Ralph Droms for the above.

  'This also brings up an important point about reaching consensus:
   Consensus does not really involve compromising.  Compromising
   implies that there remains something wrong with the outcome, but
   that the objector has simply given up.'

I read compromise as something intermediate between two 
things.  Consensus is used for conflict resolution.  It's not 
possible to resolve an issue if the two sides are not ready to 
compromise.  If you have two sides you end up with a King Solomon 
scenario.  It is very difficult to resolve the issue then.  Maybe 
conciliatory may be a better term to express the idea (see text 
quoted above).


The draft uses objection and objector in discussing about 
consensus.  That works in a formal or legalistic context.  In an IETF 
context you end up being the person standing out as you raised an 
objection.  Arguments do not have to be for or against 
(objection).  It's difficult for me to find the words to explain 
this.  I see that you used the word concerns in Section 4.


In Section 3:

  If the chair finds, in their technical judgement, that the issue
   has truly been considered, and that the vast majority of the working

Is it technical judgement or the technical issue has been 
considered?  For the former, the chair ends up taking a technical 
decision.  For the latter, the chair only has to use judgement.


  that the vast majority of the working group has come to the conclusion
   that the tradeoff is worth making

If you consider the arguments instead you don't have to get into 
majority and minority.


 Now, a conclusion of only rough consensus relies heavily on the good
  judgement of the consensus caller...

I like that paragraph.

RFC 3929 broaches consensus from a different angle.  I'll highlight 
the following: There must be a clear statement of the decision to be 
reached.  The decision process used to get there is based on 
consensus.  However, it is not easy to attain consensus.  Rough 
consensus is the lesser barrier when consensus is not possible.  In 
other words rough consensus is not the default choice (re: rough 
consensus and running code).  The draft explains that by using 
single intransigent person as an example.  Section 2 discusses 
about lack of disagreement.  Lack of disagreement can also be a sign 
that the working group has not carefully considered the question.


It is not possible to reach consensus on the musings in the 
draft.  I'll pick a sentence: it is a good solution to a real 
problem, even if the non-experts don't have the ability to fully 
judge the details.  There is a theory that the good solution would 
be chosen by a group which includes a significant number of 
non-experts.  If the questions being asked are too complex, it can 
end up with the wrong decision being taken.  If the group is 
segmented (e.g. multishareholder :-)), it can lead to a biased decision.


There are different types of consensus; e.g. the consensus of the 
girls, which is unappealable.

back by popular demand - a DNS calculator

2013-02-14 Thread Joe Touch

Hi, all,

By popular request, I've restored the DNS calculator function as an
operational service. See:

http://www.isi.edu/touch/tools/dns-calc.html

(this was designed for a Sigcomm OO session, but it's been used several
places as an example why the DNS should NOT be anything more than a
mapping service)

Joe

PS - if you do happen to use it as an example, please do drop me a note;
I'd be very glad to track that info. and/or include a pointer to any
classes that use it.

 There are cases when a show of hands can be used.  The sentence that
 follows the quoted text explains when to use humming.

It seems to me that this kind of misses the point.  Consensus-
based decision making is not simply not voting, but it's processy
and a mechanism for reaching a decision collaboratively.  Unfortunately
it's been the case for a very long time that the IETF does not
actually do that, that participants don't understand what it
means to use rough consensus for reaching decisions, working
group chairs often don't understand, IESG members often don't
understand, etc.  So if people in the process tend to see it
as a particular variant on voting, and they're incorrect, it's
probably a mistake to use mechanisms that tend to support the
incorrect view.  Hand raising looks so much like voting that
it's confusing.

 It's not possible to resolve
 an issue if the two sides are not ready to compromise. 

This is probably *the* principal problem in consensus
decision-making.  The participants have to be invested
in making the process work, and in having a mutually
satisfactory outcome.  That's very, very often not the
case in the IETF, and I'm enthusiastic about Pete's draft
as a result - as much about culture transfer as about
process normativity and improvement.

In some sense what's under discussion actually exists in
the IESG, with DISCUSSes being blocking, etc.  The difference,
of course, is that at some level there's an expectation of
altruism from IESG members but not of IETF participants.

There's a huge issue here with education.  And again, kudos to
Pete for taking this on.  It's a very steep hill.

 There are different types of consensus; e.g. the consensus of the girls,

Whut?

Hi Jari, although I was asked to complete an AppsDir review of this
document, on reading it several times I realized that my feedback is
more personal and less from the Apps Area perspective, so I am sending
a more general message.

On 2/6/13 4:49 PM, The IESG wrote:
 
 The IESG has received a request from an individual submitter to
 consider the following document: - 'Experiences from Cross-Area
 Work at the IETF' draft-arkko-iesg-crossarea-02.txt as

Section 3 begins:

   From an IETF participant's point of view, it is important that there
   is a working group where the technical topic that he or she is
   interested in can be discussed.

I'm not convinced that IETF participants really care whether the
institutional machinery of WG formation has been put in place. In my
experience, a fair amount of interesting work has happened outside of
any WG (e.g., Jeff Hodges and I worked on RFC 6125 on a
special-purpose IETF mailing list, not in a WG). As long as there's
some kind of venue, discussion can occur.

A related note on the following sentence in Section 1:

   If the work is
   interesting, the necessary people come to the meetings and work on
   the specifications.

Well, meetings (in the sense of WG sessions, or even IETF meetings)
aren't truly necessary if there is some other appropriate venue available.

IMHO, Section 2 could benefit from examples of cross-area work
involving RAI and Apps. Current and recent WGs include PRECIS (with
involvement from Apps, RAI, Security, and Ops/Mgt), ALTO (straddling
Apps and Transport), OAUTH (straddling Apps and Security), CORE (in
Apps but with close connections to 6lowpan in Int), PAWS (it was an
open question whether it would end up in Apps or Ops/Mgt), and current
efforts to define multi-stream support in MMUSIC, CLUE, and RTCWEB.
The Apps and RAI AD can probably provide further insight here.

In Section 3:

   Cross-area work is needed,
   of course, in any situation where a particular technical problem does
   not cleanly map to one organization.

Is an IETF area truly an organization? Isn't the organization here
the IETF?

In Section 4:

  But it
  is also possible that concerns raised in one forum are not
  understood in another, and this can lead to an effort going
  forward after finding the lowest bar forum to take it up.

By forum you seem to mean IETF area.

OLD
  Similarly, requests for cross-area review are relatively
  infrequent or sent only to a particular subset of people in an
  area (such as a directorate).
NEW
  Similarly, requests for cross-area review are relatively
  infrequent or sent only to a particular subset of people in an
  area (such as a directorate or related working group).

I tend to agree with Benoit that the scope of, and audience for, the
suggestions in Section 4 are not particularly clear. Unfortunately, I
do not yet have actionable suggestions for improvement.

Well-known web servers such as Apache and web proxies like Squid
support event logging using a common log format.  The logs produced
using these de facto standard formats are invaluable to system
administrators for troubleshooting a server and tool writers to craft
tools that mine the log files and produce reports and trends.
Furthermore, these log files can also be used to train anomaly
detection systems and feed events into a security event management
system.  The Session Initiation Protocol (SIP) does not have a common
log format, and, as a result, each server supports a distinct log
format that makes it unnecessarily complex to produce tools to do
trend analysis and security detection.  This document describes a
framework, including requirements and analysis of existing
approaches, and specifies an information model for development of a
SIP common log file format that can be used uniformly by user agents,
proxies, registrars, and redirect servers as well as back-to-back
user agents.

This document is a product of the SIP Common Log Format Working Group of the 
IETF.

This is now a Proposed Standard.

The SIPCLF working group has defined a Common Log Format (CLF)
framework for Session Initiation Protocol (SIP) servers.  This CLF
mimics the successful event logging format found in well-known web
servers like Apache and web proxies like Squid.  This document
proposes an indexed text encoding format for the SIP CLF that retains
the key advantages of a text-based format while significantly
increasing processing performance over a purely text-based
implementation.  This file format adheres to the SIP CLF information
model and provides an effective encoding scheme for all mandatory and
optional fields that appear in a SIP CLF record.  

This document is a product of the SIP Common Log Format Working Group of the 
IETF.

This is now a Proposed Standard.
