Chapter 21 Load Balancing Table 80 Load Balancing FIELD DESCRIPTION Dissociate station when overloaded Select Enable to "kick" connections to the AP when it becomes overloaded. If you set this option to Disable, then the AP simply delays the connection until it can afford the bandwidth it requires, or it shunts the connection to another AP within its broadcast radius. The kick priority is determined automatically by the NWA and is as follows: • Idle Timeout - Devices that have been idle the longest will be kicked first. If none of the connected devices are idle, then the priority shifts to signal strength. • Signal Strength - Devices with the weakest signal strength will be kicked first. Apply Reset Note: If you enable this function, you should ensure that there are multiple APs within the broadcast radius that can accept any rejected or kicked wireless clients; otherwise, a wireless client attempting to connect to an overloaded NWA will be kicked continuously and never be allowed to connect.

The first one is to "delay" a client connection. This means that the AP withholds the connection until the data transfer throughput is lowered or the client connection is picked up by another AP. If the client is picked up by another AP then the original AP cannot resume the connection. For example, here the AP has a balanced bandwidth allotment of 6 Mbps. If the red laptop (R) attempts to connect and it could potentially push the AP over its allotment, say to 7 Mbps, then the AP delays the red laptop's connection until it 268 NWA-3160 Series User's Guide
