MULTIPATH AND OPTIMAL SPECTRUM CONTINUITY BASED METHOD FOR SPECTRUM DE-FRAGMENTATION IN PBIT/S OPTICAL SWITCHING NODE OF FLEXIBLE BANDWIDTH OPTICAL NETWORKS
This paper proposes a novel Routing and Spectrum Assignment(RSA)method in Pbit/s optical switching node: Multipath and Optimal Spectrum Continuity based(MOSC)method for de-fragmentation.This method mitigates spectrum fragmentation occurs in Pbit/s optical switching node of flexible bandwidth optical networks due to dynamic allocation of spectrum resources for new connections.Simulation results show that the novel strategy achieves a better spectral efficiency and a smaller blocking probability with high adaptability to the traffic rate variation.
