Abstract
A method for high-availability operation is provided. The method includes communicating state information from each of a plurality of network elements to at least a first master network controller. The method includes communicating transformed state information from the first master network controller to the plurality of network elements and to each of a plurality of follower network controllers. The method includes continuing the high-availability operation with a new master network controller selected from among the plurality of follower network controllers as a failover, using the transformed state information in the new master network controller and in the plurality of network elements, responsive to a failure of the first master network controller. A network controller system is also provided.
