Hi, >>> 4) How does trickle ICE work without “relaxing” RFC3264 O/A? It seems >>> like you really want to be able to trickle via updated offers that >>> may be generated prior to the corresponding answer or reject? >> >> One of my comments on the trickle draft was about that. The draft says >> that a new offer can be sent "at any time", but my comment was that it >> should be according to 3264. > >That's not exactly what the draft says. What it does say is: > > At any point of ICE processing, a trickle ICE agent may receive new > candidates from the remote agent. Correct. And, it is of course true in one sense, because STUN requests creating peer reflexive candidates can of course be received at any time :) >> IF we are going to relax 3264 (I really hope we are NOT), it needs to >> be clearly described somewhere. We cannot have a number of I-Ds doing >> it "on the run"... > > I don't see how trickle ICE would require any changes to the O/A model. > Candidate trickling semantics are completely separate from those in 3264. > > Yes, the 3264 offer may, in some cases, contain a first batch of candidates and the the 3264 may have to be delayed until ICE processing yields valid pairs for every component but that's about it. > > Am I missing something? I guess the question was whether one, after the first batch of candidates have been sent in an offer, should be allowed to send the second batch in a new offer - before an answer to the previous offer has been received. That would be against 3264. Regards, Christer
