Technical Summary
The Stream Control Transmission Protocol (SCTP) is a
transport protocol originally defined to run on top of the
network protocols IPv4 or IPv6. This document specifies
how SCTP can be used on top of the Datagram Transport
Layer Security (DTLS) protocol, and in turn on top of
User Datagram Protocol (UDP). This line-up allows
RTCWeb/WebRTC applications to use a modern
transport protocol (SCTP) with end-to-end security
(DTLS) while traversing NATs (UDP).
Working Group Summary

plus the WG chair. The work replied to RTCweb requirements.
Feedback was received from RTCweb implementors during
document development. A WGLC ended 28th February 2014,
with some reviews that resulted in an updated document. Since
then discussion has focused on which version of DTLS to
mandate. This discussion concluded in November 2014.
