WebRTC in workers

[tidoust]

Idea discussed during the last WebRTC F2F meeting, see summary of discussion.

As described in the summary, main benefits would be:

• Having a single and more persistent WebRTC connection if done in service worker
• Having a more flexible connection than WebSocket
• Processing data out of the main thread

First step would probably be to enable data channel support in workers. Support for media channels requires more study.

Discussed during June 2018 WebRTC F2F, and planned investigation happening in the WG

there is active work in that direction in the WebRTC Working Group:

• Support for data channel in workers
• Support for MediaStreamTrack in workers
• Support for RTCPeerConnection in workers

moving to evaluation

The desire to expose data channels in worker was brought up again recently as part of a discussion on enabling P2P mesh networks on top of WebRTC - an explainer is expected to emerge from these discussions
