draft-ietf-tsvwg-rsvp-app-id-vv-profiles - interest?

The tsvwg and mmusic WGs have two related drafts that have expired.  Noting a dearth of community
engagement, the authors have raised the question as to whether interest still exists in these drafts and
whether the work should continue.  The drafts are:


The intent of these drafts is to allow for fine-grained classification of traffic flows by introducing a
"traffic class label" such as "" or ""
that can be signaled to various entities in the network.  Within SDP, the labels can be used by certain
network elements like SBCs to assist in prioritization of media flows or DSCP marking at network edges,
identification of various types of flows active in the network, to give instructions to endpoints on how
to signal traffic classification to network elements (e.g., via RSVP), or to instruct endpoints as to
which DSCP value to apply to traffic flows (assuming a local mapping is defined), etc.  The companion work
in tsvwg is targeted at use of the traffic class label concept within RSVP, allowing a network router or
switch to better determine how to handle RSVP requests, to map a given traffic classes label to a specific
DSCP value (facilitates proper remarking of flows), etc.

If there's interest in pursuing this work, please post to the list or let the WG chairs know.  Absent
interest, draft-ietf-tsvwg-rsvp-app-id-vv-profiles will likely be removed from the tsvwg WG's list
of planned work sometime after the Prague meeting.

New draft: draft-khademi-alternativebackoff-ecn-00.txt

A group of us have been working together to get better than current ECN
using a simple sender side change (this is not intended to compete with
work on Accurate ECN) and only the existing router ECN marking.

Please see the draft below, and do send comments and questions to this
list. In particular we'd like to know if others have interest in this work
being presented to the TSV WG.

Finishing: draft-ietf-tsvwg-sctp-failover


There is some editorial work needed to prepare
draft-ietf-tsvwg-sctp-failover for IESG review. The RFC 2119 usage
generally now looks good. Can I encourage you (Karen) as the document
editor to take the XML and provide the final edits needed to finish this.

I believe the WG was promised it would be sent to the IESG before IETF-93,
which means starting a WGLC in a week or two.

Best wishes,

Gorry & David
(tsvwg co-chairs)


As I recall the proposed next steps from the last IETF meeting were:

•  All technical issues raised including standards language, are (believed
to have been) resolved. &#8232;
•  BUT... some re-structuring would still be beneficial, given PS &#8232;
•  Next step would be a -11 revision:
&#8232; – Implement the agreed technical resolutions&#8232; – Still
improve language and some restructuring

Extract from notes of meeting:

            send these faster. If not, then follow the user. If you make the

Fw: [apps-discuss] James Polk

For the benefit of those not on the apps-discuss list...

------ Forwarded Message ------
From: "Alissa Cooper" <alissa <at>>

Subject: [apps-discuss] James Polk

I wanted to let you know that our colleague and friend James Polk passed 
away last week. James participated in the IETF for over a decade. Over 
the years he made many valuable contributions that spanned the areas, 
with particular focus on SIP, emergency services, geolocation, and 
differentiated services. Beyond his technical work, he sought to make 
improvements in the role of WG chair and the IETF overall. I think we 
all knew him as a fierce defender of the solutions he believed in who 
also had a softer side. He will be missed at the IETF and at Cisco.

Please keep James' family in your thoughts.
