The extension can be used with the S= DP offer/answer mechanism to negotiate the usage of a single transport (5-t= uple) for sending and receiving media described by multiple SDP media descr= iptions ("m=3D" sections). Such transport is referred to as a "BUNDLE trans= port", and the media is referred to as "bundled media". The "m=3D" sections= that use the BUNDLE transport form a BUNDLE group.=20 This specification defines a new RTP Control Protocol (RTCP) Source Descrip= tion (SDES) item and a new RTP header extension. This specification updates RFCs 3264, 5888, and 7941.=20 This specification obsoletes RFC 8843. This document is a product of the Multiparty Multimedia Session Control Wor= king Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protoc= ol for the Internet community, and requests discussion and suggestions for = improvements.
