This is a tiny media server for WebRTC SFU. It is designed for testing and optimizing WebRTC at high user scale, and will be applied to atm0s-media-server.
The project is kept simple and easy to understand, making it easy to test with different runtimes and optimization techniques like AF_XDP and Io-Uring.
Everything is SAN-I/O.
- Controller: init workers, bridge between shared I/O (http-server) and workers
- Worker: handle media packets, and send/recv to/from other workers
- Bus: crossbeam channel for inter-worker communication
- Whip protocol
- Whep protocol
- Single port UDP
- Io-Uring
- AF_XDP
Default build release: cargo build --release
