Jitsi Meet setup to scale single meeting over multiple videobridges

TimmiORG · December 3, 2022, 11:29am

Hi all,
looks like I need some help.
I want to create a setup which allows multiple videodriges to be used for the same meeting. I understood that OCTO is used that. But I’m not able to find recent documentation for that.

The setup from the link above is working for me. But I understood that this is not solving the resource issue for bigger conferences.

I guess it is related to this:

Existing bridge does not have a relay, will not consider other bridges

Beside that basic setup I have added into the sip-communicator.properties of the JVBs:
org.jitsi.videobridge.REGION=vbr
Means vbr1 and vbr2.

More less what is written here: This is tutorial to configure octo feature on jitsi. · GitHub

Would be great if I could get some pointers to look into.

Best regards
Christoph

Hi all,
I guess I manage to find the missing bit in my setup:

github.com

jitsi/jitsi-videobridge/blob/master/doc/relay.md

# Setting up relays (cascaded bridges)

### Relays
Relays (aka secure octo) use ICE and DTLS/SRTP between each pair of bridges, so a secure
network is not required. It uses and requires colibri websockets for the
bridge-bridge connections (endpoints can still use SCTP).

Relays are only usable with version 2 of the colibri protocol.

## Jitsi Videobridge configuration

### Relay configuratioon
Relays can be configured with the following properties in `/etc/jitsi/videobridge/jvb.conf` (also see
[reference.conf](https://github.com/jitsi/jitsi-videobridge/blob/master/jvb/src/main/resources/reference.conf#L132)).
```
  videobridge {
    relay {
      enabled=true
      region="region1"
      relay-id="unique-id-of-the-jitsi-videobridge-instance"

Currently it is looking quite promising.
