The turn-density is described as following in draft: "a turn-density parameter that indicates how many times each TURN server should record itself in the overlay."
I think when the number of turn servers is certain, a turn server registers in the network more times, which will help peers to find it. Conversely, when the number of turn servers is certain, if a turn server registers in the network only few times, it is more difficult that the turn server resource-id generated by the peers randomly equals to the turn server resource-id that a real turn server registered. So peers have to probe more reource-ids. So, I think if turn-density is high, peers are easy to find a turn server.

I believe this is correct. The higher turn-density the more candidate resource-id names there are, which means that the likelihood of there being a server at each resource-id (holding the actual number of servers constant) decreases. Thus, if turn-density (which, remember, is your estimate) is too high, then you have to probe a lot of resource-ids -Ekr 2010/11/2 <[email protected]> The text is as follow in the draft: If turn-density is too high, then the process of finding TURN servers becomes extremely expensive as multiple candidate Resource-IDs must be probed. But I think this sentence is incorrect, and it should be "If turn-density is too low". Do you think so?
