Abstract
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 specification obsoletes RFC 8843.
