Round Robin Load Balancing

Round robin load balancing is an optional SiteMinder user store object setting. Round robin load balancing distributes requests evenly over a set of user stores, which:

Note: Consider the following:

In round robin mode, a Policy Server distributes requests across all user stores that the SiteMinder user store object lists. A Policy Server:

  1. Sends a request to the first user store that the user store object lists.
  2. Sends a request to the second user store that the user store object lists.
  3. Sends a request to the third user store that the user store object lists.
  4. Continues sending requests in this way, until the Policy Server has sent requests to all available user stores. After sending requests to all available user stores, the Policy Server returns to the first user store and the cycle begins again.

Note: Configure load balancing with failover to add the benefit of redundancy in the event of a user store failure. For more information about configuring load balancing and failover, see the Policy Server Configuration Guide.

The following diagram illustrates the user store round robin process:
