A New Internet-Draft is available from the on-line Internet-Drafts directories.
 This draft is a work item of the DiffServ Applied to Real-time Transports Working Group of the IETF.

        Title           : Differentiated Services (DiffServ) and Real-time Communication
        Authors         : David Black

Abstract:
   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 Code Points (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 (e.g., reordering) have transport protocol
   interactions, particularly with congestion control functionality.  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.
