Session Description Protocol Offer/Answer Procedures for Stream Control Transmission Protocol over Datagram Transport Layer Security Transport
RFC 8841, “Session Description Protocol Offer/Answer Procedures for Stream Control Transmission Protocol over Datagram Transport Layer Security Transport”, is a Proposed Standard document published in January 2021 by C. Holmberg, R. Shpount, S. Loreto, G. Camarillo. The canonical text is published by the RFC Editor.
Abstract
The Stream Control Transmission Protocol (SCTP) is a transport protocol used to establish associations between two endpoints. RFC 8261 specifies how SCTP can be used on top of the Datagram Transport Layer Security (DTLS) protocol, which is referred to as SCTP-over-DTLS.
This specification defines the following new Session Description Protocol (SDP) protocol identifiers (proto values): "UDP/DTLS/SCTP" and "TCP/DTLS/SCTP". This specification also specifies how to use the new proto values with the SDP offer/answer mechanism for negotiating SCTP-over-DTLS associations.
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.
