Study of optimization of virtual topology for wavelength-routed networks in the presence of dynamic traffic demand

This research examined the optimum requirements for revamping virtual topology for wavelength-routed networks under dynamic traffic demand for mesh physical topology networks. We analysed the optimization of congestion and entire output using the Yen’s K-shortest path algorithm, which is a new approach to investigate the optimum condition for transmission according to time and the number of users. We also consider energy usage during optimal path selection. Previous studies have primarily focused on providing configuration strategies exclusively for selected light paths, with limited consideration for the overall physical topology configuration. Contrarily, the method proposed in this paper can be applied to optimize light path scenarios across various physical topologies.
