3.8 Load balancing of requests

Load balancing is a function that improves overall system availability by equally distributing processing to parallel J2EE servers (typically seen in a cluster configuration). Load balancing can distribute create and invoke requests from clients to servers, processes, and threads.

The following table shows the structure of this section.
