Re: secdir review of draft-ietf-simple-msrp-sessmatch

2010-09-03 Thread Gonzalo Camarillo
Hi Ted,

 Thanks for your message and your consideration of the points I raised.
  Given the
 scope of changes below, my first suggestion is that the author team actually
 go ahead with a draft incorporating these changes, so that we can discuss
 based on the actual text.  I also suspect that a second last call will
 be necessary as
 a result.

the plan is to give the authors some time to discuss with all of you who
sent comments on the draft so that the authors understand how to address
them. Depending on the nature of the changes needed, we may need to IETF
LC it again (as you suggest above) or even let the WG have an additional
look at it.

But for now, thanks for following this up.

Cheers,

Gonzalo

2010-09-03 Thread Thomas Walsh


-Original Message-
From: ietf-announce-boun...@ietf.org [mailto:ietf-announce-boun...@ietf.org] On 
Behalf Of NomCom Chair
Sent: Friday, September 03, 2010 10:49 AM
To: IETF Announcement list
Subject: Nomcom 2010-2011: Timeline and Nominations Update 


Hi Folks,

The call for nominations has been open now for just under a week and 
this is a good time for an update.  

Nominations:

The nominations are arriving at a good pace and remember nominations 
remain open until October 1.  Full details on the call may be found in 
https://datatracker.ietf.org/ann/nomcom/2468/

2010-2011 NomCom Timeline:
--
* Nominations period: August 27 - October 1, 2010
* Feedback collection: Starts September 7, 2010 (projected date)
* Questionnaire responses deadline: October 8, 2010
* Deliberations: October 1 - November 6, 2010
* Final deliberations and Interviews: November 7 - December 17, 2010
   o 3rd IETF: November 7-12, 2010
* Write-ups and other preparations: December 20 - January 7, 2010
* Send to confirming bodies: January 10, 2010
* Announce confirmed candidates:
   o 1st IETF: March 27 - April 1, 2011

Questionnaires
--
Nominees are requested to fill out the questionnaires related to their 
nomination and return them no later than October 8.  The IESG 
questionnaire is already on the NomCom wiki.  For the IAB, IAOC and 
IETF-Chair positions, the NomCom members have been updating the 
questionnaires and these will be available on the wiki in the next few 
days.  I will notify the IAB/IAOC/Chair nominees directly when their 
respective questionnaires are available.

Open List:
--
As you already know, NomCom 2010-2011 will follow the policy for Open 
Disclosure of Willing Nominees described in RFC 5680. The first 
posting of the open list should be available in the next few days, 
followed by regular updates. I will send another announcement once it 
is publicly available along with a request for feedback on the 
nominees.

Feedback Collection:

Once the open list is available, the entire community will be invited 
to provide feedback. I will send a further announcement requesting 
feedback on the nominees, describing how to submit feedback, and how to 
view the open list of nominees.  As this is dependent on the 
availability of the first posting of the open list of willing nominees, 
I am moving the projected start date for feedback from September 3 to
September 7.

Thank you,

Thomas Walsh

Re: Tools logins -- Aaaargh!

2010-09-03 Thread Henrik Levkowetz
Hi Dale,

On 2010-08-31 18:08 Worley, Dale R (Dale) said:
 There is probably a better place to complain about this, but...
 
 There are various IETF tools web pages.  But I have a devil of a
 time using them because they do not identify themselves usefully when
 asking for a login.  There are multiple login databases in the whole
 IETF tools suite, and experienced users know which database controls
 access to which tool.  But for us unwashed masses, there is no way to
 guess which web pages demand which password because they are named
 inconsistently.
 
 Let me propose:
 
 * Each password database has a *single* name which is the only name
 that it is ever referred to by, such as IETF tools login and IETF
 datatracker login.
 
 * Each login prompt gives the *single* name of the password database
 that it is driven by.

Thanks for the suggestion, it's good.  However...

I went ahead and changed the AuthName directive in the Apache config
files to specify IETF tools login instead of IETF a moment ago.
I then tested logging in, and couldn't, and then realised that since
the tools servers are using digest authentication, the digest will
change when the realm changes and all the passwords in current use
(2508 at the moment) will be invalidated.

So I had to revert it back to the old setting :-(

We've had as a goal for some time to move to having the same login/pw
for both the datatracker and the tools pages; I think we'll have to
try to move forward with that plan in order to handle the situation,
rather than the quick fix proposed above.


Best,

Henrik

2010-09-03 Thread Phillip Hallam-Baker
There is a fundamental problem with the way that Internet services are sold.

At present I have two companies that would like to sell me 'higher
speed' Internet service but I have absolutely no way to evaluate their
claims. In particular I have no way to know if changing provider or
paying my current provider more would make my existing applications
run any faster or better.

What I do know is that my Vonage service was fine when I first
subscribed but is now unusable. I have no way to know if changing
provider would change that. If I could be sure that one of the
carriers did not have a vested interest in sabotaging my VOIP service
from competing providers, that would be reason enough to switch.

One would like to sell me higher speed but will not raise their 250Gb
monthly bandwidth cap even if I pay more for the service.


I am quite willing to pay for higher bandwidth Internet. But at the
moment I have no idea what the value proposition that is being
presented to me in those offers. And if I don't know I am pretty sure
that Mrs B. Muggins has not got a clue.


So in my view the problem here is that when I pay for an X Mb/sec
connection at the moment I have no real way of knowing whether that is
really X Mb/sec all the time or X/n Mb/sec when I am using a service
that competes with my carrier.

There are two ways that this can get sorted. The first is that the
carriers can work out a way to address the issue and explain to the
customer what they are really offering. The second is regulation.

I really don't see why a regulation need amount to anything more than
the fairness in pricing rules that have been applied to other
industries who have proved to be unable to get it together on their
own. If I pay for X Mb/sec thats what I should get.

2010-09-03 Thread Michael Richardson

Thank you for your review.

 Pekka == Pekka Savola pek...@netcore.fi writes:
Pekka In S 11 on Packet Forwarding:

Pekka1.  This specification only covers how a successor is
Pekka selected from the DODAG Version that matches the

Pekka ... How is RPLInstanceID marked in the IPv6 header of the
Pekka packet being forwarded?  Are you modifying IPv6 packet
Pekka forwarding and processing algorithms here (must look into the
Pekka packets)?  That would be a major change. (You're really
Pekka referring to the hop-by-hop header processing here.)

So, this is a signficant but as yet unsolved problem.
No details of the RPL protocol itself depend upon how in, the end, the
packets are marked.

At the beginning, many of us thought that the FlowLabel was the right thing
to use.   And it works very well as long as the RPL network does not
need to interact with other networks.  

Applications that run on RPL nodes that need a non-default behaviour
need to be aware of what RPLinstanceID to pick (and this is a
provionsing issue), and thus it will in fact be the application setting
the flow label, not an intermediate node. 

Pekka It is a bit strange to see that S 17 on manageability does
Pekka not mention security management, because one of the key
Pekka problems there (as argued in the draft as well) is how do you
Pekka manually configure and maintain shared keys on all these
Pekka devices.

I agree that it is a concern --- most of the deployment scenarios (which
are in a series of RFCs published by the WG last fall) are installed by
a single contractor into a single
  commercial-building/house/factor/power-transmission-system
They initialize all the devices in the test lab, and then deploy them.

I think this is because 90% of the participants in the group think that
link-layer security provided by Zigbee is going to solve all of their
problems.I am very skeptical about this.

It might tell you something about customer service and might tell you if
there is a pattern of promising more than is delivered, but the last
mile of the connection is highly variable. Depending on the
carrier technologies, there may be distance issues and/or issues
re. folks the link is shared with, etc.

The only way to know is to make parallel installations and test them
using carefully constructed methodologies to try to factor out other
variables like origin server load, backbone load, etc. Then there
is all the automatic stuff most users aren't aware of which uses
up bandwidth and is almost impossible to identify. Close to a no
win situation for consumer class services.

I know from repeated experience that my installed speed will be downrated
from the promised speed. It has never not happened with multiple
providers and locations.

Well first .. I do want to congratulate Russ for actually injecting a bit of

a individual. I'm personally +1 on his comments. The problem we collectively
have is that there is very little or no technical clue in the NN discussion,
a problem some of us that inhabit the orbit of the 495 DC beltway see quite
often.

Brian is equally correct in noting that being quoted out of context is par
for the course in DC circles, however it is vitally important that those of
us who can, point out to our National Regulatory Authorities the reality of
how the Internet actually operates and what we are doing to address ongoing
issues of network management and congestion control. 

This is extremely important in the ongoing discussions among NRA's on how to
transition classic PSTN and Emergency services from Analog POTS to a IP

How Neutral Is The Internet?: Existing Limits Are In The Spotlight As
ATT And A Consumer Advocacy Group Squabble Over Net Traffic
by Eliza Krigman
Thursday, Sept. 2, 2010

Whether the Internet is truly a democratic forum was called into
question this week in a dispute about Internet traffic management
between ATT and the consumer advocacy group Free Press.

The feud boiled down to what it means to have paid prioritization, a
phenomenon viewed as anathema by advocates of Internet openness, and to
what extent preferential treatment of content already takes place. The
issue is at the very heart of a broader debate about what regulatory
steps are necessary, if any, to ensure the Internet remains an engine of
economic growth and a platform of equal value to people across the
socioeconomic spectrum.

ATT, in a letter filed with the Federal Communications Commission on
Monday, argued that paid prioritization of Internet traffic, contrary to
claims made by Free Press, is already a common practice of Web
management and consistent with protocols set by the Internet Engineering
Task Force. Largely unknown to people outside the technology field, IETF
is a professional organization composed of engineers that develop
standards for the Internet; for over two decades, it has played an
integral role in the management of the Internet.

The current chair of the IETF, Russ Housley, disagrees with ATT's
assessment.

ATT's characterization is misleading, Housley said. IETF
prioritization technology is geared toward letting network users
indicate how they want network providers to handle their traffic, and
there is no implication in the IETF about payment based on any
prioritization.

Dedicated lines of service, according to ATT, are examples of current
paid prioritization schemes, a concept Free Press flatly disagrees with.

ATT constructed bogus interpretations of 'paid prioritization' that
reflect no arguments or statements made by the FCC or any proponents of
net neutrality, said S. Derek Turner, research director of Free Press.
The group calls paid prioritization an anti-consumer practice where
third-party content owners can pay an Internet service provider to cut
to the front of the line in Web traffic. It's a practice that would
lead to a pay-to-play scenario where only big business could afford the
premium channels needed to compete, net neutrality advocates say,
thereby squeezing the little guys out of the market.

But ATT dismisses those assertions, saying Free Press' acceptance of
dedicated lines of service as a management practice is hypocritical
given its stance against paid prioritization.

2010-09-03 Thread Richard Bennett
 Thank you for replying Brian. I've not only read the requisite RFCs, 
I've also implemented DiffServ over 802.11e. My implementations, like 
those of everyone else who has done this, invoked the prioritization 
mechanisms in 802.11e. This is a very common case. Another common case 
implements DiffServ using 802.1d priorities.


If you want to say that DiffServ is not itself a priority scheme but 
rather a system for selecting the use of priority schemes at the Data 
Link (or comparable facilities,) you're making a distinction that's too 
fine for the press. As Russ is now invoking your message to support his 
view that payment for premium service is contrary to the wishes of IETF, 
that's a problem.

Re: My comments to the press about RFC 2474

2010-09-03 Thread Richard Bennett


  
  
Brian's paper on DiffServ confirms the fact that prioritization is
part of the standard. Here are the two relevant quotes:

"In the original design of IP [33], a byte known as the “type of
service (TOS) octet” was reserved in the header of every packet.
This was defined to contain two important fields: a three-bit
“precedence” value and three TOS bits. The precedence was intended
as a simple priority marker, where priority 0 got the worst
treatment and priority 7 got the best." (p. 1480) 

"The Diffserv working group has taken the approach that a few
fundamental PHBs should be standardized early. These should derive
from some existing experience (primarily from limited deployment and
experimentation with use of the IP precedence field to select
forwarding behaviors) and might be implemented using a variety of
specific mechanisms. The PHBs standardized so far are as follows...

"• Class selector behaviors: here seven DSCP values run from 001 000
to 111 000 and are specified to select up to seven behaviors, each
of which has a higher probability of timely forwarding than its
predecessor. Experts will note that the default behavior plus
  the class selectors exactly mirror the original eight IP
  Precedence values." (p. 1487)

This is very straightforward.

Diffserv is about layer 3 queuing mechanisms. It isn't about mapping
to primitive layer 2 prioritisation.

We did keep backwards compatibility with IP Precedence in diffserv,
and I suppose one could implement those particular PHBs by mapping them
to layer 2 prioritisation. But the more subtle PHBs like EF and AF
simply cannot be mapped to preemptive priority queues without
destroying their defined semantics.

 If you want to say that DiffServ is not itself a priority scheme but
 rather a system for selecting the use of priority schemes at the Data

No, I am not saying that. That is IMHO a faulty interpretation
of the intent of diffserv. In particular, I don't see how one can
read RFC 2597 and RFC 3246 and imagine that they can be mapped to
layer 2 priority.

He's not saying that. He's effectively saying what I'm saying: payment
models are outside the scope of the standards, which don't require any
particular payment model in order to perform their job.

Re: My comments to the press about RFC 2474

2010-09-03 Thread Richard Bennett
 Let's go back to your original comment, the one that Russ has quoted 
elsewhere. You said: It has been consistently hard to explain that 
diffserv is not a prioritisation scheme, even within the technical 
community, let alone to the regulators and the media. Your 
clarification is that DiffServ deals with multiple queuing disciplines, 
which may or may not be priority based and you get into EF and AF that 
in most implementations will end up using dedicated facilities of some 
sort, although service providers may be able to use these dedicated 
facilities for generic traffic if there's no EF or AF to send.


I can see why it's hard to explain this subtle distinction. You're 
saying here on the list that DiffServ is a higher level abstraction than 
prioritization that neither requires nor precludes prioritization to 
implement premium services. That's fine, but if you want to say that 
DiffServ is *completely removed from the realm of prioritization,* you 
have to explain away the grandfathering of IP Precedence into the 
standard. I think that you mean to say that DiffServ is *more than* a 
prioritization scheme, it's a general architecture for Internet QoS.


But even that's not correct. In fact, DiffServ is an Internet QoS 
architecture that explicitly offers priority-based services by design, 
and may also offer other types of assured or expedited services, except 
nobody really knows how that might actually work in a real scenario (or 
maybe they do, and it's just us humble developers who don't.)


Russ said to the press that he considers ATT's belief that the RFCs 
envisioned payment for premium services implemented over DiffServ or 
MPLS to be invalid. I find this puzzling as there are numerous 
references to payment for premium services in the RFCs ATT cites, such 
as RFC 2638:


At the risk of belaboring an analogy, we are motivated to provide
services tiers in somewhat the same fashion as the airlines do with
first class, business class and coach class. The latter also has
tiering built in due to the various restrictions put on the purchase.
A part of the analogy we want to stress is that best effort traffic,
like coach class seats on an airplane, is still expected to make up
the bulk of internet traffic. Business and first class carry a small
number of passengers, but are quite important to the economics of the
airline industry. The various economic forces and realities combine
to dictate the relative allocation of the seats and to try to fill
the airplane. We don't expect that differentiated services will
comprise all the traffic on the internet, but we do expect that new
services will lead to a healthy economic and service environment.

I can't speak for those who have implemented EF and AF queuing algorithms;

I don't see the gap. There are a few references to possible differential
payments in some of the informational documents concerning diffserv, and nobody
denies that differential pricing is possible. There are no elements in the
normative specifications of diffserv that serve in any way to support
accounting, pricing or charging. We can't control what choices the carriers
in one particular country such as the USA adopt; and it's not our business.

The fact that journalists don't read the bit at the beginning of each
RFC that defines its status is something that we've been used to for
many years.

 Diffserv deals with multiple different queuing disiplines, which
 may or may not be priority based.

Brian's paper on DiffServ confirms the fact that prioritization is

 standard. Here are the two relevant quotes:

 In the original design of IP [33], a byte known as the “type of
 service (TOS)
 octet” was reserved in the header of every packet. This was defined
 to contain
 two important fields: a three-bit “precedence” value and three TOS
 bits. The
 precedence was intended as a simple priority marker, where priority 0
 got the
 worst treatment and priority 7 got the best. (p. 1480)

 The Diffserv working group has taken the approach that a few
 fundamental PHBs
 should be standardized early. These should derive from some existing
 experience
 (primarily from limited deployment and experimentation with use of

2010-09-03 Thread Richard Bennett
 With respect, Brian, I don't think this is simply the failure of 
journalists to discern the distinction between Informational RFCs and 
Standards Track RFCs. Nobody has made the claim that the IETF produced a 
standard for accounting and billing for QoS or anything else. 
Informational RFCs are a perfectly fine record of what certain people in 
the IETF community may be envisioning at a given time, as long as 
people understand that envisioning is not the same as requiring, 
which is basic English literacy.


This debate was also not started by ATT throwing the name of IETF in to 
the regulatory stew as Russ was quoted as saying to CNET's Declan 
McCullagh. (We didn't foresee ATT throwing our name into this 
discussion, the IETF's Housley said. He added: This characterization 
of the IETF standard and the use of the term 'paid prioritization' by 
ATT is misleading.)


The immediate debate was started by a letter filed with the FCC by a 
group called National Organizations on Aug. 2nd addressing DiffServ and 
IntServ. This letter drew a reply from Free Press invoking the name of 
IETF and interpreting DiffServ. ATT's letter offering their view of 
DiffServ was a reply to the Free Press letter, which said:


Second, it is nonsensical to portray DiffServ as something that a 
third-party content provider could pay an ISP to use for 
paid-prioritization. Either an ISP respects DiffServ flags as outlined 
by IETF and chosen by the application or they do not -- and if they do 
not, then it isn’t DiffServ. By way of analogy, an individual customer 
cannot pay a restaurant to obey the health code -- they either do or 
they don’t. If an ISP is using DiffServ, but not respecting application 
flags, then that is not the standard as outlined by the IETF. Similar to 
how Comcast was improperly using RST packets to block BitTorrent, such a 
nonstandard use of DiffServ would be entirely new, improper, and not at 
all in line with that outlined by the IETF.


So there was a chain of throwings of the name of IETF into this 
discussion before ATT jumped into to it. It would have been pretty 
damn hard for them to address the arguments that had already been made 
by Free Press without referring to IETF, so Russ' remark is, well, not 
very well informed. Perhaps he's not a professional FCC-watcher.


So what we have at the FCC at the moment is a number of people arguing 
about the meaning of RFCs because they think the RFCs (even the 
Informational ones) hold the key to understanding the spirit of the 
Internet. I think this is wonderful, because it's much more productive 
-- potentially -- than a bunch of law professors invoking end-to-end 
arguments as the First Commandment, a binding law that bans anything 
beyond best efforts as far as the eye can see.


I can see how technical people would find this whole process 
distasteful. Journalists don't understand what they're told, they don't 
ask the right questions, and they don't repeat the right comments. 
Regulators are even worse. It's no wonder that Dave Clark used his time 
addressing the FCC after me at the Harvard hearing on Comcast in 2008 to 
talk about economics. These are hard questions for the network 
engineering community to resolve, and even harder for regulators. No 
doubt about it.


But you can't blame people for trying, and you can't say go regulate 
the Internet however you want but keep the IETF's name out of it. That 
would lead to a result you really don't want to see.

I can't speak for those who have implemented EF and AF queuing algorithms;
they will have to speak for themselves.


Am I missing something when I find a gap in the dialog?

I don't see the gap. There are a few references to possible differential
payments in some of the informational documents concerning diffserv, and nobody
denies that differential pricing is possible. There are no elements in the
normative specifications of diffserv that serve in any way to support
accounting, pricing or charging. We can't control what choices the carriers
in one particular country such as the USA adopt; and it's not our business.

The fact that journalists don't read the bit at the beginning of each
RFC that defines its status is something that we've been used to for
many years.

Internet providers say the high cost of running wire or fibre to the 
house or neighborhood is prohibitive.  Telephone service used to be 
considered a regulated monopoly, and I have wondered if this model 
could work with outside plant, as a separate facility from Internet 
service.  The idea being that a regulated or even municipal entity 
builds and maintains the outside plant, with any Internet provider 
able to use it to offer service.  That way all details of the service 
are open to competition.

Questionnaires
--
Nominees are requested to fill out the questionnaires related to their 
nomination and return them no later than October 8.  The IESG 
questionnaire is already on the NomCom wiki.  For the IAB, IAOC and 
IETF-Chair positions, the NomCom members have been updating the 
questionnaires and these will be available on the wiki in the next few 
days.  I will notify the IAB/IAOC/Chair nominees directly when their 
respective questionnaires are available.

Open List:
--
As you already know, NomCom 2010-2011 will follow the policy for Open 
Disclosure of Willing Nominees described in RFC 5680. The first 
posting of the open list should be available in the next few days, 
followed by regular updates. I will send another announcement once it 
is publicly available along with a request for feedback on the 
nominees.

Feedback Collection:

Once the open list is available, the entire community will be invited 
to provide feedback. I will send a further announcement requesting 
feedback on the nominees, describing how to submit feedback, and how to 
view the open list of nominees.  As this is dependent on the 
availability of the first posting of the open list of willing nominees, 
I am moving the projected start date for feedback from September 3 to
September 7.

Protocol Action: 'Spatial Composition of Metrics' to Proposed Standard

2010-09-03 Thread The IESG
The IESG has approved the following document:
- 'Spatial Composition of Metrics'
  draft-ietf-ippm-spatial-composition-16.txt as a Proposed Standard

This document is the product of the IP Performance Metrics Working Group.

The IESG contact person is Lars Eggert.

A URL of this Internet Draft is:
http://datatracker.ietf.org/doc/draft-ietf-ippm-spatial-composition/



Technical Summary
 
This memo utilizes IP Performance Metrics that are applicable to both
complete paths and sub-paths, and defines relationships to compose a
complete path metric from the sub-path metrics with some accuracy
w.r.t. the actual metrics. This is called Spatial Composition in RFC
2330. The memo refers to the Framework for Metric Composition, and
provides background and motivation for combining metrics to derive
others. The descriptions of several composed metrics and statistics
follow.
 
Working Group Summary
 
The normal WG process was followed and the document has been discussed for
several years. The document as it is now, reflects WG consensus, with
nothing special worth noticing.
 
Personnel

Henk Uijterwaal (h...@ripe.net) is the document shepherd. Lars Eggert
(lars.egg...@nokia.com) reviewed the document for the IESG.
