Abstract: 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.

The particular node also determines a respective path cost from each reachable potential parent node of the particular node to the root node via each potential parent and a respective link metric to each potential parent node. A set of acceptable parent nodes are determined from the potential parent nodes that have a respective path cost that is less than the current path cost plus an acceptable cost increase, and also have a respective link metric that is within an acceptable range. By determining a respective number of child nodes for each acceptable parent node, the particular node may then select a new parent node based on giving preference to those having a greater respective number of child nodes.
