(TURN) relayed candidates MUST NOT be prioritized as it is always possible to other high priority candidates succeed for the WebRTC session. Also, TURN candidates is not required to be allocated for all the session. Hope trickle ICE solve these problems as the allocation shall happen.

 

IMO, it is very much possible to implement in the WebRTC network (server/endpoint) without TURN server and with reduced WebRTC session setup time.

 

Thanks

Partha

Does this mean that we should allocate v6 candidates from all v4 interfaces (for compat with v6-only endpoints), as well as allocate v4 candidates from all v6 interfaces (for compat with v4-only endpoints), and if so, which path (v6-to-TURN or v6-from-TURN) should be prioritized?

You must always allocate both v4 and v6 relayed candidates, irrespective
of what other candidates you have.

 

I am fine with that - this needs to be added to the transports document though.

 

Any thoughts on the prioritization question?
