ABSTRACT:
An optical control plane (OCP) distinct from an electronic control plane helps the setup of path routes in a DWDM network. The OCP determines the optical feasibility of any path route selected by the electronic control plane, such as operated under GMPLS protocol, and asks the electronic control plane for another path route if the optical feasibility is determined to be negative. The OCP can be set in a server or distributed across the nodes of the network.
