Abstract

Constraint-based wavelength routing comes with the cost of higher blocking probability to provide Quality of Service (QoS) guarantee in Service-guaranteed optical networks; thus a load balancing method is presented in this paper to improve the performance of constraint-based wavelength routing. Also the Modified Backward-Forward heuristic (MBFH) is proposed, which can be utilized to select an optimal lightpath with one constraint. Simulation results show that with the application of load balancing method, constraint-based wavelength routing based on the MBFH can achieve better performances in terms of blocking probability and resource utilization ability.
