Multiplexing Scheme Updates for Secure Real-time Transport Protocol
(SRTP) Extension for Datagram Transport Layer Security (DTLS)
draft-ietf-avtcore-rfc5764-mux-fixes-01
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),
Traversal Using Relays around NAT (TURN), and Stream Control
Transmission Protocol (SCTP) over UDP 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.
