Abstract
Methods, nodes and control modules are disclosed. In the method, circuitry of a first node in a mesh network converts an optical layer in a working path between the first node and a second node, to a data stream in a digital layer. The working path carries data traffic from the first node to the second node in the optical layer of the mesh network when there is no failure in the working path. Circuitry of the first node in the mesh network detects a failure in the working path due to detection of an error in the data stream in the digital layer. The circuitry of the first node establishes, through transmission of at least one signal from the first node to the second node, a restoration path in the optical layer based on, at least in part, detection of the error in the data stream in the digital layer.
