Ok, this topic has had sufficient "soak time" - having seen no objections, the Atlanta "hum" on Diffserv Classes is confirmed as the rough consensus of the tsvwg WG: > Restating - the sense of the room in Atlanta was that interactive > media (e.g., multi-media conferencing) needs to be broken out of the > existing diffserv media classes into at least one new class. As promised, I will work with James on the next steps: > If the sense of the room in Atlanta is confirmed, the next steps on > Diffserv Classes are that I will work with James to come up with a list > of all the things that he's proposing to change in > draft-polk-tsvwg-rfc4594-update and ask the list whether each one > of them needs attention (single subject/question emails). My preference is to get the answers to those questions before asking whether the tsvwg WG should adopt that draft as a WG draft.
