of the ap referring to fig2 an exemplary diagram of a flowchart illustrating a process of reassigning a client device from a first primary controller to a second primary controller when redundancy is incorporated is provided to further assist in the explanation of the process fig3 a 3c are provided in the embodiment discussed with fig2 and fig3 a 3c three controllers comprise the cluster of controllers controller_ 1 controller_ 2 and controller_ 3 referring to fig3 a an exemplary diagram illustrating an initial state of an ap to controller configuration table prior to beginning the process of reassigning an ap is provided column 300 represents the index value computed from the hash value computed from the mac address of an ap herein after u201c corresponding index value u201d that denotes the entry within the ap to controller configuration table in which the ap is to access column 310 represents the primary controller of the corresponding index value column 320 represents the standby controller of the corresponding index value a standby controller of a corresponding index value is not currently managing any ap mapped to that index value the standby controller of a first corresponding index value is the primary controller for one or more aps of a second index value referring to fig2 in.
