Hi,

Based on the input from Roman, I’ve updated the pull request.

https://github.com/cdh4u/draft-dtls-sdp/pull/26

I used separate commits for the ‘connection attribute clarification’ and the ‘TLS justification’.

Regards,

Christer

Now, I think we do need some text on WHY we also cover TLS connections since, as far as creating new connections is concerned, the ‘connection’ attribute can be used. We know that it would be needed for draft-thomson-avtcore-sdp-uks (https://datatracker.ietf.org/doc/draft-thomson-avtcore-sdp-uks/). But, AFAIK that work has not been adopted yet, so I don’t think we can use it as justification at this point?


I was thinking that we should include something like:

The pair of newly defined SDP 'tls-id' attribute values from the offer and the corresponding answer can be used to uniquely identify TLS or DTLS association. This unique identifier can be used by TLS protocol extensions to differentiate between multiple TLS and DTLS association and correlate these associations with specific offer/answer exchanges.
