switchboard

Switchboard is a scalable webrtc server built in rust!

The overall architecture is as follows:

• JSONRPC/Websocket signaling protocol
• webrtc.rs based routing engine
• pluggable coordination for multi-node operation
• Deep integration with gstreamer for multimedia processing (planned)

Roadmap

This project is currently a work in progress, and very early stages.

Phase 0 (Current)

Single node operation that can host multiple call sessions & routing between peers

Phase 1

Multi-node clustered operation with single node routing

This will likely start with redis/etcd coordination (comparable to how ion-cluster works). Cluster will support many call servers but any single session will only span a single node.

Phase 2

Multi-node sessions that can span multiple call servers & support different distribution topoligies (ie fan out trees for broadcast).

This will involve replacing MediaTrackRouter/MediaTrackSubscriber's current tokio implementation. I'd like this interface to be pluggable with different backends supported (UDP Unicast Relay, UDP Multicast groups, etc).
