Session Description Protocol Offer/Answer Considerations for Datagram Transport Layer Security and Transport Layer Security
RFC 8842, “Session Description Protocol Offer/Answer Considerations for Datagram Transport Layer Security and Transport Layer Security”, is a Proposed Standard document published in January 2021 by C. Holmberg, R. Shpount. It updates RFC 5763, RFC 7345. It has since been updated by RFC 9725. The canonical text is published by the RFC Editor.
Abstract
This document defines the Session Description Protocol (SDP) offer/answer procedures for negotiating and establishing a Datagram Transport Layer Security (DTLS) association. The document also defines the criteria for when a new DTLS association must be established. The document updates RFCs 5763 and 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 Transport Layer Security (TLS) connection, in conjunction with the procedures in RFCs 4145 and 8122.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
