Message Session Relay Protocol over Data Channels
RFC 8873, “Message Session Relay Protocol over Data Channels”, is a Proposed Standard document published in January 2021 by JM. Recio, C. Holmberg. It updates RFC 4975. The canonical text is published by the RFC Editor.
Abstract
This document specifies how a Web Real-Time Communication (WebRTC) data channel can be used as a transport mechanism for the Message Session Relay Protocol (MSRP) and how the Session Description Protocol (SDP) offer/answer mechanism can be used to negotiate such a data channel, referred to as an MSRP data channel. Two network configurations are supported: the connection of two MSRP data channel endpoints; and a gateway configuration, which connects an MSRP data channel endpoint with an MSRP endpoint that uses either TCP or TLS. This document updates RFC 4975.
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.
