How does an XMPP cluster work?

Note: The XMPP server component is not supported from version 3.0, and has been removed from the Cisco Meeting Server software.

Clustered XMPP servers within a deployment are loaded with the same configuration. Each knows the location of the others and they establish links between them. They use keep-alive messages to monitor each other and elect a primary. XMPP messages can be sent to any server. Messages will be forwarded to the primary XMPP server. The XMPP servers continue to monitor each other, if the primary fails then a new primary is elected and the other XMPP servers forward traffic to the new primary.

For more information on configuring an XMPP cluster, see the Cisco Meeting Server Scalability and Resilience Deployment Guide. (Versions earlier than 3.0.)
