This 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. This document defines a new SDP media-level attribute, 'tls-id'. This document also defines how the 'tls-id' attribute can be used for negotiating and establishing a TLS connection, in conjunction with the procedures in RFC 4145 and RFC 8122.
