Load Balancing

The Professional Access Point allows you to balance the distribution of wireless client connections across multiple access points. Using load balancing, you can prevent the performance degradation that results when a single access point handles a disproportionate share of the wireless traffic.

The following sections describe how to configure Load Balancing on your wireless network:

•Understanding Load Balancing

•Identifying the Imbalance: Overworked or Under-utilized Access Points

•Specifying Limits for Utilization and Client Associations

•Load Balancing and QoS

•Navigating to Load Balancing Settings

•Configuring Load Balancing

•Updating Settings

Understanding Load Balancing

Like most configuration settings on the Professional Access Point, load balancing settings are shared among clustered access points.

Note

In some cases you might want to set limits for only one access point that is consistently over-utilized. You can apply unique settings to an access point if it is operating in standalone mode. (See “Under- standing Clustering” on page 44 and “Navigating to Access Points Management” on page 44.)

Identifying the Imbalance: Overworked or Under-utilized Access Points

Comparison of Sessions data for multiple access points allows you to identify an access point that is consistently handling a disproportionately large percentage of wireless traffic. This can happen when location placement or other factors cause one access point to transmit the strongest signal to a majority of clients on a network. By default, that access point will receive most of client requests while the other access points stay idle much of the time.

Imbalances in distribution of wireless traffic across access points will be evident in Sessions statistics, which will show higher utilization rates on overworked APs and higher Idle times on under-utilized APs. An access point that is handling a disproportionate amount of traffic might also show slower data rates or lower transmit and receive rates due to the overload.

Specifying Limits for Utilization and Client Associations

You can correct for imbalances in network access point utilization by enabling load balancing and setting limits on utilization rates and number of client associations allowed per access point.
