A segmentation based channel scheduling scheme for improving channel utilization in OBS networks

Abstract

Channel scheduling is an important aspect in optical burst switching (OBS) networks. OBS is a promising solution for the future Internet backbone. In OBS network a key issue is data channel scheduling. In this paper we propose a channel scheduling scheme to optimize channel utilization for OBS networks with segmentation. In this paper, we propose an efficient way to organize the void intervals. The channel scheduling method is compared with existing scheduling schemes. Simulation results show that both channel utilization and burst loss ratio performance improved as compared to existing scheduling schemes.
