Abstract

Section 5.1.2 of "Datagram Transport Layer Security (DTLS) Extension to Establish Keys for the Secure Real-time Transport Protocol (SRTP)" [RFC5764] defines a scheme for a Real-time Transport Protocol (RTP) [RFC3550] receiver to demultiplex DTLS [RFC6347], Session Traversal Utilities for NAT (STUN) [RFC5389], and Secure Real-time Transport Protocol (SRTP) / Secure Real-time Transport Control Protocol (SRTCP) [RFC3711] packets that are arriving on the RTP port. Unfortunately, this demultiplexing scheme has created problematic issues:

Abstract

   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.

   This document updates RFC 5764.
