The referenced draft is a start for discussion on the implicat ions of using different DiffServ treatments for packets in the same IP flow (that is, share the same IP 5-tuple.) This will likely be of interest to RTCWEB, MMUSIC, AVTCORE, CLUE and possibly other groups that contemplate the bundling of multiple media streams on a single IP flow. 

Please take discussion to the DART working group list (copied.)

> 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 flow may cause
>   transport protocol interactions (e.g., due to 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
