SCTP Negotiation Acceleration Protocol

WebRTC Data Channels use the Stream Control Transmission Protocol (SCTP) over a Datagram Transport Layer Security (DTLS) association. The standard SCTP connection establishment requires a handshake that introduces latency. This document specifies a method to accelerate the datachannel establishment by embedding the SCTP initialization parameters within the Session Description Protocol (SDP) offer/answer exchange. This reduces the time required to open a data channel by up to two network round-trip times.
