Re: [Ice] ICE PAC: When to start the timer waiting for possible peer reflexive candidates? - discussion restart

Hi,

Ok, let's assume we DO have remote candidates, and the timer expires. We discard the fact that the timer expires, and go on checking the remote candidates, as you suggested.

Then, at some point we have checked all remote candidates, but we have NOT found successful pairs for all streams. So, since the timer already expired, we declare ICE failure.

I thought the whole idea was to still wait for some time after we have tried all remote candidates, in case we will receive peer reflexive candidates, before we declare ICE failure.

But, as I said earlier, I am fine doing as you and others suggest. All I am saying is that the draft needs to describe what to do if the timer expires while there are still untested remote candidates. If the solution is to discard the timer expiration, then it needs to be documented.
