Abstract
The present disclosure discloses a system and a method for providing radio frequency based access point load balancing in a controller cluster. Specifically, a network device detects a long-term network topology change in a network having a controller cluster, wherein the controller cluster comprises a plurality of controllers, and automatically reassigns one or more of a plurality of access points that are managed by a first controller to a second and different controller in the controller cluster without interrupting network traffic to and from client devices associated with the one or more of the plurality of access points. The access points are located within a particular radio frequency neighborhood. Also, the one or more of the plurality of access points provide adequate coverage in the particular radio frequency neighborhood in the event that the first controller and its corresponding access points after the reassignment become unavailable.
