Re: [rtcweb] SDP Offer/Answer draft-jennings-rtcweb-signaling: Glare handling

Speaking strictly as an individual (I'm in the same organization as 
Magnus, so if that means that this input has less weight so be it):

I think this discussion got a bit off track.

In the ROAP draft glaring is resolved by backing off and waiting in the 
order of seconds.

Magnus proposes another solution that resolves glaring immediately (no 
need to wait). I think this is a really good idea, especially in the 
light of that the current API proposal allows each endpoint to 
asynchronously add streams (for transmission to the other endpoint) at 
any time. This means that glaring conditions could be quite common.

Why should we design something that delays the start of those streams 
quite some time when it easily can be avoided?

Then there could (or not) be situations where the back-off resolution 
does not work at all, but I think a more efficient glaring resolution 
mechanism makes sense regardless.

(NB: If there are other ways to resolve glaring without delay I'm all 
for it, I just want to avoid that glaring would delay steam set up 
unnecessarily)
