For additional information please contact the Area Directors or the WG Chair. DiffServ Applied to Real-time Transports (dart) ------------------------------------------------ Current Status: Proposed WG Chairs: Ben Campbell Technical advisors: Martin Stiemerling Assigned Area Director: Richard Barnes Mailing list Address: dart@ietf.org To Subscribe: https://www.ietf.org/mailman/listinfo/dart Archive: http://www.ietf.org/mail-archive/web/dart/ Charter: 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, CLUE, RTCWEB, and RMCAT.
