7.6.3 Disassociating and Delaying Connections

When your AP becomes overloaded, there are two basic responses it can take. 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 laptop R connects and
it pushes the AP over its allotment, say to 7 Mbps, then the AP delays the red laptop's connection
until it can afford the bandwidth or the laptop is picked up by a different AP with bandwidth to
spare.
Figure 59 Delaying a Connection
The second response your AP can take is to kick the connections that are pushing it over its
balanced bandwidth allotment.
Figure 60 Kicking a Connection
Connections are kicked based on either idle timeout or signal strength. The NXC first looks to
see which devices have been idle the longest, then starts kicking them in order of highest idle time.
If no connections are idle, the next criteria the NXC analyzes is signal strength. Devices with the
weakest signal strength are kicked first.
