Abstract :
This paper presents the integration of quality of service (QoS) requirements in routing and wavelength assignment (RWA) problems to design wavelength-routed dense wavelength division multiplexing (DWDM) optical networks. A genetic algorithm (GA) optimization approach is employed to solve this complex and multi-constraint problem under heavy load demand matrices employing the COST239 test bench. Simulation results demonstrate that the GA is efficient to establish both bandwidth and propagation delay optimization lightpaths.
