摘要

Among the three optical network technologies being studied for future Internet, namely, optical circuit switching, optical packet switching and optical burst switching; optical burst switching is, up to now, the most likely to be implemented in the near future. Nevertheless, bursts contention persists and more work need to be done to minimize bursts loss before Optical Burst switching can be implemented. In this paper, we propose efficient bandwidth utilization and routing optimization scheme aiming at avoiding bursts contention and making better use of the large bandwidth offered by fiber links through Wavelength Division Multiplexing and Dense Wavelength Division Multiplexing. The proposed solution is based on the Hierarchical Optical Burst switching techniques and a modified hybrid algorithm of Ant Colony Optimization and Genetic Algorithm, taking into account the Streamline Effect in Optical Burst switching. Through simulation, we expect low burst lost probability and efficient use of bandwidth.
