The IESG plans to make a decision in the next few weeks, and solicits final
comments on this action. Please send substantive comments to the

Abstract

This specification defines a new Session Description Protocol (SDP)
Grouping Framework extension, 'BUNDLE'. The extension can be used
with the SDP Offer/Answer mechanism to negotiate the usage of a
single transport (5-tuple) for sending and receiving media described
by multiple SDP media descriptions ("m=" sections). Such transport
is referred to as a BUNDLE transport, and the media is referred to as
bundled media. The "m=" sections that use the BUNDLE transport form
a BUNDLE group.

This specification updates RFC 3264, to allow assigning a zero port
value to a "m=" section without meaning that the media described by
the "m=" section is disabled or rejected.

This specification defines a new RTP Control Protocol (RTCP) source
description (SDES) item and a new RTP header extension that van be
used to correlate bundled RTP/RTCP packets with their appropriate
"m=" section.
