Load balancing
Overview
Load balancing dynamically adjusts loads among APs to ensure adequate bandwidth for clients. It is
mainly used in high-density WLAN networks.
Requirement of load-balancing implementation
As shown in Figure 60 , Client 6 wants to associate with AP 3. AP 3 has reached its maximum load, so
it rejects the association request. Then, Client 6 tries to associate with AP 1 or AP 2, but it cannot receive
signals from these two APs, so it has to resend an association request to AP 3.
Therefore, to implement load-balancing, the APs must be managed by the same AC, and the clients can
find the APs.
