Hi Everyone,

I believe this version has closed all of the WGLC open issues, and fixed most or all of the reported editorial nits. I'm going to request publication.

If anyone discovers additional issues, please continue to report them. We can address those as part of the IETF last call.

> 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.  Use of different DSCPs
>   to obtain different QoS treatments within a single network 5-tuple,
>   the results (e.g., reordering) may cause 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.
