Abstract
A method and apparatus to bring up a network controller in a network of multiple network elements is described. In an exemplary embodiment, the network controller receives an indication that the network controller is booting up. The network controller is coupled to a plurality of network elements in a network, where the network controller maintains a controller database that supports a network-wide service used by the plurality of network elements. The network controller further receives state information from the plurality of network elements. In addition, the network controller builds the controller database from the state information. Furthermore, the network controller sends updates from the controller database to each of the plurality of network elements, where each of the plurality of network elements incorporates these updates into a respective network element database and the network element database is used to perform the network-wide service.
