Subject: [tsvwg] 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:

draft-ietf-tsvwg-rsvp-app-id-vv-profiles
draft-ietf-mmusic-traffic-class-for-sdp
 
The intent of these drafts is to allow for fine-grained classification of traffic flows by introducing a "traffic class label" such as "conversational.video.immersive" or "broadcast.video.surveillance" 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.

Thanks,
--David
