Abstract
During a synchronization technique, states of a primary cluster in the computer system with multiple primary controllers that provide controllers for access points and a backup cluster in the computer system with multiple backup controllers that independently provide controllers for the access points may be dynamically synchronized. In particular the primary cluster may receive configuration requests with configuration information for the access points on an input node of the primary cluster. In response, the primary cluster may store the configuration requests in a replay queue in the computer system. Then, the primary cluster may playback the configuration requests in the replay queue for the backup cluster to synchronize the states of the primary cluster and the backup cluster. For example, the configuration requests may be played back within a time interval associated with a service level agreement of a service provider of a service for the access points.
