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.
