摘要:
A method and apparatus for optimizing the resilience of a network using a combination of in-band and out-of-band signaling is disclosed. The metric used in the embodiment's algorithm to determine resilience is the maximum number of protected neighbors. Nodes closer to the controller are assigned a higher weight than those further from the controller because if their connection to the network is interrupted, all their downstream nodes will be affected and disconnected. Therefore, when determining a path to the controller, switches with alternate paths to the controller are preferred. Dedicated connections using out-of-band signaling are assigned to convert unprotected nodes to protected nodes thus improving the resilience of the network.
