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>
