Multiplexing Scheme Updates for QUIC
draft-ietf-avtcore-rfc7983bis-00.txt
Abstract
This document defines how QUIC, 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.
This document updates RFC 7983 and RFC 5764.

INTERNET-DRAFT Multiplexing Scheme Updates for QUIC 21 November 2020
1. Introduction
"Multiplexing Scheme Updates for Secure Real-time Transport Protocol
(SRTP) Extension for Datagram Transport Layer Security (DTLS)"
[RFC7983] defines a scheme for a Real-time Transport Protocol (RTP)
[RFC3550] receiver to demultiplex DTLS [RFC6347], Session Traversal
Utilities for NAT (STUN) [RFC5389], Secure Real-time Transport
Protocol (SRTP) / Secure Real-time Transport Control Protocol (SRTCP)
[RFC3711], ZRTP [RFC6189] and TURN Channel packets arriving on a
single port.
This document updates [RFC7983] and [RFC5764] to also allow QUIC [I-
D.ietf-quic-transport] to be multiplexed on the same port. For peer-
to-peer operation in WebRTC scenarios as described in [WEBRTC-
QUIC][WEBRTC-QUIC-TRIAL], RTP is used to transport audio and video
and QUIC is used for data exchange, SRTP [RFC3711] is keyed using
DTLS-SRTP [RFC5764] and therefore SRTP/SRTCP [RFC3550], STUN, TURN,
DTLS [RFC6347] and QUIC need to be multiplexed on the same port.
Since new versions of QUIC are allowed to change aspects of the wire
image, there is no guarantee that future versions of QUIC beyond
version 1 will adhere to the multiplexing scheme described in this
document.
1.1. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
