If you have deployed stand-alone Community Server multiplexers, you have two choices for setting up the load balancing mechanism.
- Set up a rotating DNS system to accomplish load balancing. Use rotating DNS to associate the IP addresses of the Community Services multiplexer machines to a single DNS name.
For example, associate the IP address of Multiplexer Machine 1 (22.214.171.124) and Multiplexer Machine 2 (126.96.36.199) to the DNS name cscluster.sametime.com.
- Set up a WebSphere® Edge Server (Network Dispatcher) in front of the Sametime® servers that you intend to cluster. Use the WebSphere Edge Server Network Dispatcher to distribute connections to the multiplexer machines. For more information, see the WebSphere Edge Server documentation, available at the website www.redbooks.ibm.com (and also provided with the WebSphere Edge Server).
The diagram below shows the Community Services multiplexers with the rotating DNS system in place. Note that the WebSphere
Edge Server can be used in place of the rotating DNS system.
