  Multiplexing Scheme Updates for Secure Real-time Transport Protocol
     (SRTP) Extension for Datagram Transport Layer Security (DTLS)
                draft-ietf-avtcore-rfc5764-mux-fixes-04

Abstract

   This document defines how Datagram Transport Layer Security (DTLS),
   Real-time Transport Protocol (RTP), Real-time Transport Control
   Protocol (RTCP), Session Traversal Utilities for NAT (STUN), and
   Traversal Using Relays around NAT (TURN) packets are multiplexed on a
   single receiving socket.  It overrides the guidance from SRTP
   Extension for DTLS [RFC5764], which suffered from three issues
   described and fixed in this document.
