Paper Abstract

This paper proposed a novel RWA algorithm based on load balance (RWALB) to solve the dynamic wavelength routing problem in new generation optical networks based on the MPLmS paradigm. In RWALB algorithm, the cost of each link is adjusted dynamically as the overall network status changing. By applying RWALB algorithm the best load balance can be produced in the overall network wavelength resource, the average blocking probability can be reduced significantly and the wavelength resources can be utilized efficiently. Through numeric simulation on NSF and EON network, it is shown that the network performance is significantly improved compared with ordinary RWA algorithm that applies shortest-path algorithm and first-fit (FF) wavelength assignment strategy.
