Abstract :
Protected circuits provisioning on an optical network based on ROADMs is demonstrated using a GMPLS control plane with physical impairments considerations (link attenuation and PMD). Therefore, messages exchanged between nodes related to signaling procedures and topological data flooding were altered, in order to carry the necessary information for WDM network control. To operate properly, a RWA algorithm is also proposed, which considers physical link characteristics in path computation. It also provides protection path computation facilities, using an optical layer recovery mechanism.
