The Session Description Protocol (SDP) provides mechanisms to
describe attributes of multimedia sessions and of individual media
streams (e.g., Real-time Transport Protocol (RTP) sessions) within a
multimedia session, but does not provide any mechanism to describe
individual media sources within a media stream. This document
defines a mechanism to describe RTP media sources, which are
identified by their synchronization source (SSRC) identifiers, in
SDP, to associate attributes with these sources, and to express
relationships among sources. It also defines several source-level
attributes that can be used to describe properties of media sources.
This document is a product of the Multiparty Multimedia Session Control Working Group of the IETF.
This is now a Proposed Standard Protocol.
STANDARDS TRACK: This document specifies an Internet standards track
protocol for the Internet community,and requests discussion and suggestions
