Abstract:
This document describes a means of multiplexing RTP streams having
different media types within a single transport connection and a
means of representing this multiplexing option in SDP so that network
nodes can easily identify groups of RTP streams and their associated
RTCP packets for differential treatment as necessary. This mechanism
can be used to complement the BUNDLE multiplexing scheme, which uses
the grouping framework to identify all media lines associated with a
single transport connection, but provides no means for network nodes
to group RTP streams and their RTCP packets for differential
treatment. RTP subsessions is an alternative to the SHIM
multiplexing proposal; it clearly partitions packets associated with
different media lines without changing the format of individual RTP
and RTCP packets, but it does not maintain a completely independent
SSRC space for each media line, as does SHIM. RTP subsessions avoid
SSRC conflicts by construction and can be used in all RTP topologies
in which all systems implement RTP subsessions, although SSRC mapping
might be needed when forwarding RTP streams from an unpartitioned RTP
session into an RTP subsession.
