A Novel Priority-based Wavelength Assignment Algorithm for Dynamic Traffic in WDM Networks

摘要

For the purpose of reducing the optical networks blocking probability, many wavelength assignment algorithms are introduced to this problem. In this paper, we propose a novel priority-based wavelength assignment algorithm for dynamic traffic in WDM networks. The objective of the algorithm is not only taking the balancing strategy, but also adopting the priority-controlled method. Analytic models and simulations are presented for the proposed wavelength assignment algorithm. By the simulation, we compare the performance of our algorithm with the others under different traffic load and different priority-class. Our algorithm yields better blocking probability performance for different priority requests and the simulation results are also discussed.
