Abstract: Systems and methods for accessing network configuration data identifying one or more working path(s) configured to transport data between source and destination nodes, wherein multiple working paths are prioritized, and including at least one first diversity weight of a first value indicative of at least one communication link in the working path(s), and at least one second diversity weight of a second value indicative of at least one communication link outside of the working path(s); calculating a disjoint protection path with the network configuration data, the first diversity weight, and the second diversity weight; the disjoint protection path including at least the source node and the destination node and at least one communication link that is mutually exclusive from the at least one communication link of the first set; and outputting at least one setup signal to configure the disjoint protection path within the mesh network.

Abstract: Nodes and methods are disclosed for protection and restoration to protect against multiple failures for multiple paths involved for the same service in mesh networks, including, determining, by circuitry of a first node in a mesh network, a failure of a working path between the first node and a second node, wherein the second node, when triggered by the failure of the working path, switches to a protection path. Methods further include establishing through transmission of at least one signal by circuitry of the first node at least one recovery path, for example, a restored-working path, after determining the failure of the at least one working path, wherein the at least one restored-working path carries a duplicate of the data traffic transmitted on the protection path in case of failure of the protection path.
