The IESG has approved the following document: - 'JavaScript Session Establishment Protocol' (draft-ietf-rtcweb-jsep-24.txt) as Proposed Standard This document is the product of the Real-Time Communication in WEB-browsers Working Group. The IESG contact persons are Adam Roach, Alexey Melnikov and Ben Campbell. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-rtcweb-jsep/ Technical Summary This document describes the mechanisms for allowing a JavaScript application to control the signaling plane of a multimedia session via the interface specified in the W3C RTCPeerConnection API and relates this signaling to the media streams and data channels which are created and managed by the application. It is effectively the core signaling protocol for WebRTC endpoints. Working Group Summary The working group process leading up to this document was quite long and required unusual levels of coordination with the W3C group producing the API and the IETF working groups responsible for the underlying mechanisms (especially those responsible for SDP, ICE, and RTP). During the process, there were some decisions which moved between groups in ways that made consensus difficult to judge because the groups were not completely congruent. The shepherd's evaluation is that the contents of this document do have consensus of the interested parties, and the responsible area director concurs. Document Quality The protocol has various levels of implementation in release versions of at least five major web browsers (Chrome, Safari, Firefox, Edge, and Opera) and in hundreds of applications. Those who contributed significant text and reviews are mentioned in the acknowledgements section. The GEN-ART review was specifically (and by request) conducted by a communications and SDP expert. Personnel Ted Hardie is the document shepherd. Adam Roach is the responsible area director.
