The IESG has received a request from the Audio/Video Transport Core Maintenance WG (avtcore) to consider the following document: - 'Sending Multiple Media Streams in a Single RTP Session: Grouping RTCP Reception Statistics and Other Feedback' <draft-ietf-avtcore-rtp-multi-stream-optimisation-08.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2015-11-24. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract RTP allows multiple media streams to be sent in a single session, but requires each Synchronisation Source (SSRC) to send RTCP reception quality reports for every other SSRC visible in the session. This causes the number of RTCP reception reports to grow with the number of SSRCs, rather than the number of endpoints. In many cases most of these RTCP reception reports are unnecessary, since all SSRCs of an endpoint are co-located and see the same reception quality. This memo defines a Reporting Group extension to RTCP to reduce the reporting overhead in such scenarios. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-avtcore-rtp-multi-stream-optimisation/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-avtcore-rtp-multi-stream-optimisation/ballot/ No IPR declarations have been submitted directly on this I-D.
