[SIPForum-discussion] ICE - Connectivity check Algorithm

Hi Rahul,
As per the RFC, I understand, Connectivity Checks for each candidate are paced out at certain rate, called as TA timer. This TA can be 20 ms minimum.
And so , if there are 2 media streams with higher to lower priority . THe high priority check will be done at say TA1 timer and the check for next priority stream
will be done at TA2 timer. And so in this case, the response for first connectivity check is not a criteria to decide on sending the next connectivity check.
it is based on periodic timers.
Regards,
Manoj Raju

Hi Manoj,Thanks for the
reply.My question was whether connectivity checks
for the media streams will begin simultaneously or one after
the other.For Eg:If I have 2 streams
say Audio and Video and Audio has highest priority. The
connectivity checks for video will start after completion of
Audio or it will start when Audio checks are still going
on.

Hi,
As per rfc 5245, the candidate pairs are sorted
based on
Priority. And
checks are done in sequence from high priority to low
priority. so connectivity checks for all pairs won't
begin at same time.

Hi , In ICE rfc 5245, it is
mentioned that connectivity checks will start for the first
media stream(as mentioned in SDP) . There is
also a mention that each media stream will have independent
timers which decides the interval between connectivity
checks and RTO for those candidates,
I have a doubt here.
Connectivity checks will begin at the same time
for all media stream
ORconnectivity checks will begin for the second
media stream only after first media stream's
connectivity checks are over.
