This draft is a work item of the Datagram Congestion Control
Protocol Working Group of the IETF.
Title : RTP and the Datagram Congestion Control Protocol
(DCCP)
Author(s) : C. Perkins
Filename : draft-ietf-dccp-rtp-02.txt
Pages : 16
Date : 2006-11-16
The Real-time Transport Protocol (RTP) is a widely used transport for
real-time multimedia on IP networks. The Datagram Congestion
Control
Protocol (DCCP) is a newly defined transport protocol that provides
desirable services for real-time applications. This memo
specifies a
mapping of RTP onto DCCP, along with associated signalling, such
that
real-time applications can make use of the services provided by
DCCP.
A URL for this Internet-Draft is:

The changes since -01 are as follows:
- Clarify The "DCCP" protocol identifier MUST NOT be used to signal RTP
sessions running over DCCP..."
- In section 4.4 "systems must assume that multiple synchronisation
sources
may be observed" -> "systems SHOULD assume..." with an explanation
that
out of band signalling may be used to override the SHOULD.
- Reference SIP when first mentioned.
- Clarify signalling of RTCP ports (end of section 5.1)
- Clarify use of service codes in the SDP example.
- Change signalling to use "a=rtcp-mux" and update references.
Any further comments are appreciated.
