A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : Real-Time Transport Protocol (RTP) Topology Considerations for Offer/ Answer-Initiated Sessions. Author(s) : Jonathan Lennox Filename : draft-lennox-avtcore-rtp-topo-offer-answer-00.txt Pages : 11 Date : 2012-03-05 This document discusses a number of considerations related to the topologies of Real-Time Transport Protocol (RTP) sessions initated using the Session Description (SDP) unicast Offer/Answer Model, especially as applied to source-multiplexed sessions. The primary observation is that certain topologies cannot be created by unicast SDP Offer/Answer. Notably, the it is not possible to negotiate the topology that RFC 5117 calls Topo-Transport-Translator (or "relay"). As a consequence of this limitation, certain topological assumptions can safely be made for RTP sessions initiated using unicast SDP Offer/Answer; and therefore, certain optimizations to RTP are possible in such sessions. This document also describes the optimizations that these assumptions make possible.
