Balance two video bridge

For example, i have two jitsi videobridge is jvb 1 and jvb 2. Now, i create a new conference on jvb 1, my stream wil go through jvb1. So if new participate want to join my conference, the stream of them go through jvb 1 or jvb 2 ? Thank you.

On a basic install of Jitsi-meet (that is, without octo), load balancing is done by Jicofo, it directs new participants to the appropriate bridge.

In this ordinary instance, the 2nd participant will be placed on JVB1 too.
