Differentiated Services (DiffServ) and DiffServ code points (DSCP) can be
used in some situations to provide quality of service (QoS). Packets with
different markings can be reordered, which can cause poor interaction with a
transport protocol that is sensitive to reordering. When RTP streams or other
real-time media (sub-)flows are used with different DSCP values with the same
transport 5-tuple, there may be transport protocol interactions. There are also
environments where the DSCP markings are removed or remarked.

This WG will write a document that explains the limitations that exist with
DiffServ when used with RTP in general as well in the specific RTCWeb cases.
The WG will coordinate with relevant WGs, including TSVWG, AVTCORE, MMUSIC,
