Subject: WG Review: WebRTC Ingest Signaling over HTTPS (wish)
The WebRTC Ingest Signaling over HTTPS (wish) WG in the Applications and
Real-Time Area of the IETF is undergoing rechartering. The IESG has not made
any determination yet. The following draft charter was submitted, and is
provided for informational purposes only. Please send your comments to the
IESG mailing list (iesg@ietf.org) by 2023-12-11.

Charter: https://datatracker.ietf.org/doc/charter-ietf-wish/
The WISH working group is chartered to specify a simple, extensible,
HTTPS-based set of signaling protocols to establish one-way WebRTC-based
audiovisual sessions between broadcasting tools, media players and real-time
media broadcast networks.
Background:
WebRTC defines a set of wire protocols for real-time media transmission, as
well as a profile of the Session Description Protocol (SDP) for setting up
and controlling the associated media streams. Because of its typical use
cases, and to increase overall flexibility, WebRTC did not specify a wire
protocol for exchanging SDP messages, leaving the creation of such protocols
up to the applications that use WebRTC. This works well when WebRTC clients
are vertically integrated with the servers they communicate with, as it
allows for rapid iteration of new features.
At the same time, the use of WebRTC as a mechanism for large-scale media
broadcast is gaining popularity, and unlike more vertically integrated uses
of WebRTC, WebRTC-based media distribution networks would benefit immensely
from being able to re-use the several broadcasting tools that have been
developed over time.
To date, these media distribution networks have employed their own
proprietary signaling protocols to establish the connection between
broadcasting tools and the network, generally requiring either bespoke
software or customized modifications to existing tools.
With the large number of available tools and the growing number of real-time
media distribution networks, this ad-hoc approach to creating custom
protocols for establishing sessions clearly does not scale. The real-time
broadcasting ecosystem would benefit immensely from a set of common protocols
to meet this goal.
Deliverables:
The product of this working group will be a specification for a simple,
extensible, HTTPS-based signaling protocol set to establish one-way
WebRTC-based audiovisual sessions between broadcasting tools and real-time
media broadcast networks, and between those networks and the media players.
This working group will use existing HTTPS, WebRTC, and SDP mechanisms to the
extent possible. While no extensions to those core protocols is expected, the
working group may consider such extensions if they are necessary to meet the
requirements of broadcasting tools and networks. Any such work will be
coordinated with the HTTPBIS, MMUSIC, and/or MOPS working groups, as
appropriate. Additionally, this working group will coordinate with HTTPBIS
and HTTPAPI to assure that the HTTP protocol is being used according to
current best practice.
While there may be other problems that the proposed mechanism may solve or
nearly solve, such as general purpose bidirectional realtime communication
(telephony, video conferencing etc), adding explicit protocol support for
those use cases is not in scope for the WISH working group.
Milestones:
Dec 2024 - Submit WebRTC-HTTP egress protocol to IESG for publication
