Abstract

See full text

A method for network controller initialization that includes identifying a controller connected to a network as a primary controller that manages switches in the network. One or more other controllers connected to the network are identified as secondary controllers. A failover priority table is created. The failover table indicates an order that the one or more other controllers will replace the controller as the primary controller in the event that the controller enters a failure mode. The failover priority table is broadcast to the switches in the network.
