WebRTC Data Channel server to clients UDP communication. Is it currently possible?

Question

Is it possible to use WebRTC Data Channels on Node.js in a way that mimics the functionality of WebSockets except using UDP?

In essence I want to have a server runni

Answer 1

We have implemented the exact same thing: a server/client way of using WebRTC. Besides we also implemented data port multiplexing, so that server would only need to expose one data port for all rtcdata channels.

A quick summary of how it is achieved:

• We implemented in nodejs, using wrtc library. But the same principal could be applied to other implementations.
• The server exposes a control port, so that the client will exchange SDPs with the server for establishing their data channel.
• To support data port multiplexing, At the server, we modify both peer's SDK, so that
  1. Client will always connect to the same server ip:data_port
  2. We implement a UDP data proxy inside the server, so that it can be the bridge between the server webrtc engine and the client.
