Why need `ice-pwd` and `ice-ufrag` when we have DTLS #305

I don't know, but this is a question I had when reading about these.

UPD: it's later touched here so maybe at least say it.

WebRTC does not use DTLS for communication for UDP hole punching. STUN Req/Res is used directly.

I think it is better to use Discussions instead of Issues for questions about the WebRTC mechanism itself, and I prefer to use Issues as a place to exchange written issues.

What I mean is that I think this should be reflected in the book. Or does it still hold?

Ice-pwd and ice-ufrag are still used in WebRTC, where peers send STUN Req/Res to each other to realize UDP hole punching.

Does this answer your question?

I'm sorry, I meant the point about using discussions XD Thanks for the answer!
