We present a network operation tool called Impairment Aware Lightpath Computation Engine (IALCE) that incorporates an impairment-aware routing and wavelength assignment (RWA) algorithm. We perform experiments illustrating the flexibility of the engine and the performance of the algorithm.
Summary form only given. The evolution of optical networks should aim at improved cost economics, reduced operations efforts, scalability and adaptation to the future services and application requirements. Considering the evolution trend of optical networks, the core networks of the future will have a translucent and eventually transparent optical network structure. The realization of dynamic and...
In transparent optical networks with no regeneration, the problem of capacity allocation to traffic demands is called ldquorouting and wavelength assignmentrdquo. Much work on this topic recently has focused on the dynamic case, whereby demands arrive and must be served in real-time. In addition, due to lack of regeneration, physical impairments accumulate as light propagates and QoT may become inappropriate...
We present excellent performance results for a novel offline physical layer impairment aware routing and wavelength assignment algorithm for various transparent all-optical networks, while considering dedicated path protection.
