About Installing Web Conferencing in a Load Balancing Configuration

Load balancing in Cisco Unified MeetingPlace Web Conferencing makes use of a cluster of Web Conferencing servers to spread the active meeting load, allowing you to scale the number and size of meetings that your deployment can support. It also provides failover capabilities for meetings–if one Cisco Unified MeetingPlace Web Conferencing server is unavailable or unreachable, meeting clients will reconnect to another server, even if they are currently connected to a meeting that is in progress when the connection is interrupted.

You can view the amount of web-conferencing load per server from the Web Server administrative page. This information is displayed only on internal web servers.

To configure load balancing, you should understand the following concepts in this section:

•Restrictions for Installing Web Conferencing in a Load Balancing Configuration, page 4-2

•Web Conferencing Clusters, page 4-2

•Web Conferencing Load Balancing and Failover Capability, page 4-4
