Therefore, this document is now submitted as an individual submission to TSVWG. To provide some context ... during the Atlanta IETF, it became clear that having this document in RTCWEB (where it was a WG draft) was confusing on at least 2 counts: (1) TSVWG is the place in the IETF where we should be making any recommendations about use of DiffServ; it would get crazy if every WG had its own set of guidance about this. (2) It seemed to be advocating using multiple 6-tuples (address pairs, port pairs, protocol, and DSCP) that differ only in their DSCP, for distinguishing the QoS desires of individual packets within an RTCWEB flow that's muxing potentially lots of different things (voice, video, bulk, and interactive data) with different QoS desires. This was potentially not going to interact well with things we have been talking about in RMCAT, like allocating congestion responses between elastic and inelastic sub-flows. If those sub- flows are on separate 6-tuples, this may not make any sense, as they'd be seeing different queues within the network. So, in summary, TSVWG is the right place to talk about this draft, though I'm not sure it's technically a very good idea, myself, given other work being done in the IETF currently. -- Wes Eddy MTI Systems
