Title : A Framework for SDP Attributes when Multiplexing
Author : Suhas Nandakumar
Filename : draft-ietf-mmusic-sdp-mux-attributes-07.txt
Pages : 90

Abstract:
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. Typically media associated with individual media
descriptions ("m=" lines) represent seperate RTP Sessions and thus
carried over individual underlying transport layer flows. For
scenarios where SDP is used to negotiate the usage of single 5-tuple
for sending and receiving media associated with multiple media
descriptions, it is required to understand the semantic implications
of the SDP attributes associated with the RTP Media Streams
multiplexed over a single underlying transport layer flow.
The purpose of this specification is to provide a framework for
analyzing the multiplexing characteristics of SDP attributes. This
specification also categorizes the existing SDP attributes based on
the framework described herein.
