Abstract
Nodes and methods are disclosed, including, circuitry of a source node in a mesh network retrieving information indicative of network topology; identifying a working path from the source node to a destination node; identifying potential protection segments of the working path, wherein a potential protection segment has at least one disjoint protection path available for the segment; creating a hypothetical network topology comprising the nodes of the working path and hypothetical links between the nodes, wherein the hypothetical links represents potential protection segments identified, and the links are assigned a weight; executing a Shortest Path Algorithm on the hypothetical network topology; identifying as optimal segments the potential protection segments represented by the hypothetical links determined as being in the shortest path by the Shortest Path Algorithm; generating and transmitting a message communicating need for resources in case of failure of the optimal segments.
