This specification defines a new Session Description Protocol (SDP)
Grouping Framework extension called '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 defines a new RTP Control Protocol (RTCP) Source
Description (SDES) item and a new RTP header extension.

This specification updates RFCs 3264, 5888, and 7941.

This document is a product of the Multiparty Multimedia Session Control Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
