RTP Requirements for RTC-Web (-03)

Posted on 03 September 2011 in category rtcweb

This version makes the following changes relative to the -02 draft:

• Removed discussion of multiplexing for RTP sessions entirely, pending submission of a proposal for multiplexing audio and video within an RTP session (as discussed at IETF 81).
• Added a reference to draft-ietf-avtcore-srtp-vbr-audio-03 in Security Considerations.
• Added a recommendation that draft-ietf-avtcore-srtp-encrypted-header-ext-00 be used when the client-to-mixer and mixer-to-client audio level indication RTP header extensions are in use in SRTP encrypted sessions.
• Added Slice Loss Indication and Reference Picture Selection Indication messages as OPTIONAL loss tolerance mechanisms.

These are intended to address the comments and discussion during the IETF 81 meeting in Quebec City.
