Patent ID: 8861488

Claim:
A method of selecting access points of a wireless network as redundant aggregation devices, the access points providing clients with access to the wireless network, comprising: monitoring, by M access points that are available as redundant aggregation devices, parameters of the access points; selecting, by the M access points, a plurality of N access points as redundant aggregation devices based upon the monitored access point parameters, wherein each redundant aggregation device is connected to a wired network, and wherein a process of the selecting the redundant aggregation devices is distributed among the M access points, wherein N is greater than two but less than M; wherein each of the redundant aggregation devices stores redundant client information for access when a client device roams to a new access point; sensing, by the M access points, when one of the selected N aggregation devices fails; selecting a replacement access point as a replacement redundant aggregation device based upon the monitored access point parameters, wherein a selection process for selecting the replacement access point is run by access points that are connected to the wired network, and that are not selected as redundant aggregation devices.
