• This version completes the rewrite for clarity which was started in the -08 version. There should be no technical changes, only significant editorial clarifications.

• This version is a minor update that includes a number of editorial changes to clarify the scope of the draft, and improve readability. The draft also notes the limitations in using per-packet marking for differential quality of service across flows in a single RTP session.

• This is a keep-alive version, to prevent the draft expiring. The only changes are to update the references.

• The main change in this version is to extract the contents from Section 6.4 of this draft, and incorporate them into the draft on Sending Multiple Media Streams in a Single RTP Session instead.

• This revision adds sections 6.4.1 on Timing out SSRCs and 6.4.2 on Tuning RTCP transmissions, and fixes the use of RFC 2119 normative language in some places, but is otherwise a minor update.

• This version makes the following changes:

  • Note that RFC 3551 mandates that audio and video are run on separate RTP sessions, and so needs to be updated if we are to allow multiple media types in a single RTP session. Section 6.1 is updated to specify this.
  • Update Section 3.3, to clarify what is meant by architectural equality. In particular, note that RTP requires a common session bandwidth, so any flows that are multiplexed together in an RTP session need to have similar bandwidth requirements.
  • Update Section 5.1 to further clarify that all flows that are to be multiplexed together need to have similar bandwidth requirements, due to the requirement for a common RTCP reporting interval.
  • Update Sections 6.3 and 7.2 to clarify use with the RTP payload format for Generic FEC.
  • Update Section 6.4 to discuss the constraints imposed by the single RTCP reporting interval.
  This draft will be discussed in the AVTCORE working group meeting at IETF 85 in Atlanta in November 2012.

• Our draft on Multiple Media Types in an RTP Session was adopted as a work item of the IETF AVTCORE working group during the IETF 84 meeting in Vancouver in July 2012. The -00 working group draft brings the references up-to-date, but is otherwise identical to the last individual submission.
