Abstract
A system is described that includes a first network controller and a second network controller. The first controller operates as a master controller and the second controller operates as a standby controller for a set of access points. Using a set of VRRP advertisements between the first and second controllers, the second controller may (1) determine that the first controller has failed independent of any determination by the access points and (2) send a failover request to the access points. The failover request may cause the access points to use previously established tunnels between the second controller and each of the access points. By transmitting a failover request message from the second controller to the access points upon the detection by the second controller that the first controller has failed and independent of any determination by the access points, the system reduces network access downtime for the access points.
