Please see the mail attached below that I just sent to avtcore announcing a personal ID I just submitted on the topic of media multiplexing. I am sending this notice to rtcweb since this is the group that triggered recent work on RTP multiplexing. I also request the rtcweb chairs consider giving me some time to present this work at next week's interim meeting if there is time on the agenda. It might be useful to discuss the ideas in the ID before avtcore meets in Vancouver.

There are superficial similarities with an expired draft from last year in http://tools.ietf.org/id/draft-rosenberg-rtcweb-rtpmux-00.txt, but my draft has a different take on the use of SSRC as the basis for multi session multiplexing that I think is superior and worthy of consideration as a potential replacement for BUNDLE and/or SHIM. Please comment. Richard -----Original Message----- From: internet-drafts@ietf.org [mailto:internet-drafts@ietf.org] Sent: Sunday, June 03, 2012 5:16 PM To: Ejzak, Richard P (Richard) Subject: New Version Notification for draft-ejzak-avtcore-rtp-subsessions-00.txt A new version of I-D, draft-ejzak-avtcore-rtp-subsessions-00.txt has been successfully submitted by Richard Ejzak and posted to the IETF repository. Filename: draft-ejzak-avtcore-rtp-subsessions Revision: 00 Title: Media multiplexing with Real-time Transport Protocol (RTP) subsessions Creation date: 2012-06-04 WG ID: Individual Submission Number of pages: 9 Abstract: This document describes a means of multiplexing RTP streams having different media types within a single transport connection and how to represent this multiplexing option in SDP. This mechanism is an alternative to the BUNDLE and SHIM proposals currently under active consideration in AVTCORE. Instead of adding an extra multiplexing header as in SHIM to allow multiple RTP sessions within a single transport connection, or using the payload type field to separate different media streams within a single RTP session, this document describes how to partition the existing SSRC space to create RTP subsessions from a single RTP session. A filter can be used to identify each RTP subsession for different QoS handling as necessary. RTP subsessions can be treated like RTP sessions with a few restrictions. In particular, SSRC mapping may be needed when forwarding RTP streams into an RTP subsession to avoid SSRC conflicts, but there are few use cases in which this limitation is a concern and RTP subsessions can be disabled if necessary.
