Hi all,

We didn't have time for this open issue on Monday meeting so we'll take it here on the list.

While ICE is no longer bound to SIP and SDP offer/answer, the document uses terms "offer" and "answer" heavily, starting in the title ("ICE: A Protocol for NAT Traversal for Offer/Answer Protocols") and abstract ("ICE can be used by any protocol utilizing the offer/answer model [...]").

I think we need to update the title and abstract so that it's more clear that protocols that don't follow the o/a model are not excluded. Text suggestions are welcome. Maybe in title we call this just "ICE: A Protocol for NAT Traversal".

Then, throughout the text we need to refer to the exchange of candidates somehow. Originally this was referred to as the "SDP offer" and "SDP answer". Currently we use "ICE offer" and "ICE answer". My suggestion would be to keep the "(ICE) offer/answer" terminology here but clarify in the beginning of the document that with the offer and answer we refer to the ICE candidate exchange.

Opinions?


Cheers,
Ari
