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,
