Using jitsi on multiple servers

Hi,
I want to know if a guide exists to install and configure jitsi to use multiple servers.

Thank you very much
Angelo

Do you mean load balancing ?
here’s a tutorial about it https://www.youtube.com/watch?v=LyGV4uW8km8

thanks for the link. I saw it and I’ve noticed that a conference is not splitted among the videbridge servers.
is it possible to use multiple videobridges in the same conference?
I want to increment the number of the participants.
Thank you very much
Angelo

Actually, I think the current load balancing algorithm is based on number of conferences only, which is not enough in my opinion.

I quickly read that Jitsi supports geographical bridge cascading but I’m not sure whether it’s related to load balacing or not. Maybe someone from Jitsi team could confirm this.

it’s quite new.
so, it’s possible to split the conference.

# Setting up Octo (cascaded bridges)

## Jitsi Videobridge
Add these properties to `/etc/jitsi/videobridge/sip-communicator.properties` to
enable support for Octo:
```
org.jitsi.videobridge.octo.BIND_ADDRESS=10.0.0.1 # the address to bind to locally
org.jitsi.videobridge.octo.PUBLIC_ADDRESS=1.2.3.4 # the address to advertise (in case BIND_ADDRESS is not accessible)
org.jitsi.videobridge.octo.BIND_PORT=4096 # the port to bind to
org.jitsi.videobridge.REGION=region1 # the region that the jitsi-videbridge instance is in
```

You need to make sure that all of the bridges can communicate via the socket
addresses described in the properties above, and that the network is secure.

## Jicofo configuration
To enable the use of Octo in jicofo, you need to set the "selection strategy" by
setting this property in `/etc/jitsi/jicofo/sip-communicator.properties`:
```
org.jitsi.jicofo.BridgeSelector.BRIDGE_SELECTION_STRATEGY=RegionBasedBridgeSelectionStrategy

We still don’t use it for balancing, but plan to do so.

I try to setup octo according to your link.

the jicofo log shows that the participant is directed to different jvb, but allocate channels failed.

net.java.sip.communicator.service.protocol.OperationFailedException: Creator thread has failed to allocate channels on: jitsi-videobridge.myserver, msg: Failed to allocate colibri channels: response is null. Maybe the response timed out.```

I have checked the jvb log.
