Architecture

before develop modules, you should know how it works

1. Architecture

2. Signal flow

SDK<---grpc--->signal<---nats--->Room/ISLB<---nats--->signal<---grpc--->SDK
                                    ||
                                  [Redis]

• SDK send signals to Signal by grpc (example:join and so on)
• Signal do business handle and send signals/events to Room/ISLB by nats
• Signal get a SFU node from ISLB when SDK join a session
• Signal exchange SDP with SFU by nats
• SDK and SFU start ICE, send/recv video streams after ICE state is connected
• Other Signal will receive events at the same time(example:some one joined/publish stream)

3. Media streams flow

SDK<----webrtc---->SFU<----webrtc---->SDK

Tips:

• keys words see faq
• you must config stun server or nat1v1 in config.toml
