Abstract

In some embodiments, an apparatus includes a first controller configured to be operatively coupled within a network having a set of network nodes, a forwarding gateway and a configuration entity. The first controller is configured to manage session state and node state associated with the set of network nodes independent of the forwarding gateway. The first controller is configured to fail over to a second controller when the first controller fails, without the forwarding gateway failing over and without the configuration entity failing over.
