Embodiment Construction

[0015] In some embodiments, an apparatus comprising a first control and configuration of wireless access point (CAPWAP) module embodied in at least one of memory or processing means, the first control and configuration of wireless access point configuring becomes a backup control module designated as a wireless access point during the first time period. The first CAPWAP control module is configured to receive, during the first time period, status information associated with the wireless access point from a second CAPWAP control module designated as the wireless access point's during the first time period. Primary control module. The first CAPWAP control module is also configured to receive status information associated with the second CAPWAP control module from the second CAPWAP control module during the first time period. The first CAPWAP control module is configured to be automatically designated as the primary of the wireless access point during a second time period after ...

Abstract

In some embodiments, an apparatus comprises of a first Control And Provisioning of Wireless Access Points (CAPWAP) module implemented in at least one of a memory or a processing device that is configured to be designated as a backup control module for a wireless access point during a first time period. The first CAPWAP control module is configured to receive state information associated with the wireless access point during the first time period from a second CAPWAP control module. The second CAPWAP control module is designated as a primary control module for the wireless access point during the first time period. The first CAPWAP control module is configured to be automatically designated as the primary control module during a second time period after the first time period and in response to the second CAPWAP control module not operating according to at least one predefined criterion.
