RFC 7657 Title: Differentiated Services (Diffserv) and Real-Time Communication Author: D. Black, Ed., P. Jones Status: Informational Stream: IETF Date: November 2015 Mailbox: david.black@emc.com, paulej@packetizer.com Pages: 26 Characters: 67721 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-dart-dscp-rtp-10.txt URL: https://www.rfc-editor.org/info/rfc7657 DOI: http://dx.doi.org/10.17487/RFC7657 This memo describes the interaction between Differentiated Services (Diffserv) network quality-of-service (QoS) functionality and real- time network communication, including communication based on the Real-time Transport Protocol (RTP). Diffserv is based on network nodes applying different forwarding treatments to packets whose IP headers are marked with different Diffserv Codepoints (DSCPs). WebRTC applications, as well as some conferencing applications, have begun using the Session Description Protocol (SDP) bundle negotiation mechanism to send multiple traffic streams with different QoS requirements using the same network 5-tuple. The results of using multiple DSCPs to obtain different QoS treatments within a single network 5-tuple have transport protocol interactions, particularly with congestion control functionality (e.g., reordering). In addition, DSCP markings may be changed or removed between the traffic source and destination. This memo covers the implications of these Diffserv aspects for real-time network communication, including WebRTC. This document is a product of the DiffServ Applied to Real-time Transports Working Group of the IETF. INFORMATIONAL: This memo provides information for the Internet community.
