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.
