Abstract

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.
