Technical Summary

The document defines the SDP offer/answer procedures for negotiating and establishing a DTLS association.  The document also defines the criteria for when a new DTLS association must be established.  The document updates RFC 5763 and RFC 7345, by replacing common SDP   offer/answer procedures with a reference to this specification. The document defines a new SDP media-level attribute, 'dtls-id'.

Working Group Summary

There was originally no controversy or anything else to note. Version 22 of this draft underwent 
IETF Last Call. Subsequently, the working group elected to add support for TLS, which was a 
material change. Therefore the IETF Last Call was repeated with version 26.

Document Quality

There are existing implementations of the protocol, and a number of vendors have indicated that they intend to implement it.
