As promised, here's the -00 dart WG draft.  I think I incorporated almost
everything that was discussed in the meeting, but I've surely missed a
few things - please comment (on list, or send me editorial changes directly).

I want to call attention to this Editor's Note on draft organization:

   [Editor's Note: Current section structure skips around topics
   somewhat.  The editor suggests restructuring to put real-time/RTP
   material first (new section 2, consisting of current sections 2, 2.1
   and 3), then DiffServ Background (new section 3, consisting of
   current sections 2.2, 2.3, 2.6 and 2.7, followed by discussion of
   interactions (new section 4, consisting of current sections 2.4, 2.5
   and 5) and guidelines (current section 4, renumbered to new section
   5).]

If this change is made, I will submit a version that only contains the
text rearrangement before making any other changes.  The "game plan" that
I've discussed w/Ben (WG chair) is to revise the draft over about the next
week with the resulting version going to WG Last Call, so reading this
draft sooner rather than later might be a good idea.

Thanks,
--David

> Abstract:
>    This document 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).  As a
>    result, use of different DSCPs within a single traffic stream may
>    cause transport protocol interactions (e.g., reordering).  In
>    addition, DSCP markings may be changed or removed between the traffic
>    source and destination.  This document covers the implications of
>    these DiffServ aspects for real-time network communication, including
>    RTCWEB.
