See sections Load balancing and Rebroadcasting of a stream to another WCS server via WebRTC.
Example 1. Configuring the load balancer:
<loadbalancer mode="FEWESTCALLS" randomize="false">
<node id="1">
<ip>192.168.1.11</ip>
</node>
<node id="2">
<ip>192.168.1.12</ip>
</node>
</loadbalancer>
Example 2: Configuring static CDN for rebroadcasting of a stream:
<loadbalancer mode="roundrobin" stream_distribution="webrtc">
<node id="1">
<ip>edge1.mydomain.com</ip>
<wss>443</wss>
</node>
<node id="2">
<ip>edge2.mydomain.com</ip>
<wss>443</wss>
</node>
</loadbalancer>
Parameters description:
Element | Default value | Description |
|---|---|---|
mode | FEWESTCALLS | FEWESTCALLS - select the server with the least active calls. RANDOM - select the server at random. ROUNDROBIN - select servers consequentially one by one (used in case of static CDN). LESS_LOADED_NODE - select the server with minimum CPU load. |
randomize | false | If both servers do not have active calls and mode is set to FEWESTCALLS, the balancer will select the server at random if this parameter is set to true. |
stream_distribution | webrtc | Technology to use to rebroadcast the stream in case of static CDN |
node id | empty | WCS server numeric identifier |
ip | empty | IP address or FQDN of the WCS server that responds via HTTP and provides information about load and calls. |
wss | empty | Port for data exchange via Secure Websocket |
