Hi Martin, >It is really hard following these threads, but it looks like this is being over-thought. > >"This document defines what it takes to obtain, maintain, and lose consent to send. Consent >to send applies to a single 5-tuple. What applications choose to do with this information is not >described in this document." > >Add that to the introduction perhaps. We run the risk of expanding scope otherwise. I agree that we don't need to specify application behaviour. But, I think we do need to be clear regarding the impacts on the transport/ICE layer, when/if/how it can be later re-used etc. >As for the question of re-acquisition of consent, I think that we should keep it simple. For this: > >"After consent is lost for any reason, the same ICE credentials MUST NOT be used on the affected 5-tuple again. >That means that a new session, or an ICE restart at least, is needed to obtain consent to send." My question is how/if the consent lost impacts "normal" ICE (STUN keep-alives etc), transport layer heartbeats etc. Also, as the entity may still receive media on the 5-tuple, that also means it still have to respond to incoming STUN requests etc. I think that should be clear in the draft. >I think that we should consider a keep alive as application data, and subject to rules of consent. >The text should note that firewall and NAT bindings could be lost, instead. I am ok with such approach, as long as we document it :) What about DTLS heartbeats, and other information sent on the transport layer? I ASSUME the entity will maintain those, as it still may receive media Regards, Christer
