Technical Summary This document defines how Datagram Transport Layer Security (DTLS), Real-time Transport Protocol (RTP), RTP Control Protocol (RTCP), Session Traversal Utilities for NAT (STUN), Traversal Using Relays around NAT (TURN), and ZRTP packets are multiplexed on a single receiving socket. It overrides the guidance from RFC 5764 ("SRTP Extension for DTLS"), which suffered from four issues described and fixed in this document. Working Group Summary There has been good consensus in the AVTCORE WG. However, due to potential impact on the other protocols (TLS and STUN/TURN), this document was also last called in TLS and TRAM WG. This resulted in some changes to ensure the solution was mutually acceptable. Document Quality There are not yet any known implementations of this fix. The document has been well reviewed and last called in several WG to ensure that the protocol impacts was acceptable by the different main responsible WGs. Personnel Magnus Westerlund is the Document Shepherd. Ben Campbell is the Responsible Area Director.
