Abstract:
This document describes a model for the lightweight use of SDP Offer/
Answer in WebRTC. The goal is to minimize reliance on Offer/Answer
exchanges in a WebRTC session and provide applications with the tools
necessary to implement the signalling that they may need in a way
that best fits their custom requirements and topologies. This
simplifies signalling of multiple media sources or providing RTP
Synchronisation source (SSRC) identification in multi-party sessions.
Another important goal of this model is to remove from clients
topological constraints such as the requirement to know in advance
all SSRC identifiers that they could potentially introduce in a
particular session.
The model described here is similar to the one employed by the data
channel JavaScript APIs in WebRTC, where methods are supported on
PeerConnection without being reflected in SDP.
This document does not question the use of SDP and the Offer/Answer
model or the value they have in terms of interoperability with legacy
or other non-WebRTC devices.
