This draft was replaced by draft-ietf-rtcweb-rtp-usage

• Colin Perkins, Magnus Westerlund, and Jörg Ott, RTP Requirements for RTC-Web (.txt|.pdf), Internet Engineering Task Force, August 2011, Work in progress (draft-perkins-rtcweb-rtp-usage-03.txt).

• 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.

• This version of the RTP requirements for RTC-Web draft includes a greatly expanded discussion of the requirements for multiplexing RTP sessions on different UDP ports. This is intended for discussion at IETF 81 in Quebec City.

• This is our contribution to the RTC-Web interim meeting.

• This is an initial draft discussing which RTP features and extensions are appropriate for use in the RTC-Web context. The idea is to stimulate discussion, and (hopefully) to ensure that the RTC-Web solution uses a modern RTP protocol stack.

This document discusses usage of RTP in the context of WebRTC work. It discusses important factors of RTP to consider by other parts of the solution, it also discusses which RTP profile to support and which RTP extensions that should be supported.
