About SFU

WebRTC communicates, basically not via server, but directly in P2P. In multi-person conversation, it is common to use a method called “full-mesh connection” which employs multiple P2P connections simultaneously, while ECLWebRTC provides a media server called SFU to realize stable conversation with more persons.

As image and voice streams are sent to all participating members, terminal load will increase if the number of the members increases.

As image and voice streams are sent only to the server (SFU), terminal load can be reduced compared with full-mesh connection.

How to use

You can use SFU from JavaScript SDK, iOS SDK and Android SDK. RoomAPI provided by ECLWebRTC has two modes, SFU and Full-Mesh, which can be switched easily. Please refer to API Reference for details on how to use.
