Abstract(in English) | In Optical Burst Switching (OBS) networks, collision avoidance techniques called Contention Resolution have been studied to avoid collision of bursts. Deflection Routing, which is a typical method for Contentin Resolution, can avoid collision by forwarding a burst to an alternate path when two bursts compete the same link. However, the Deflection Routing results in reducing throughput perfomance under heavy traffic load condition. In this paper, we propose the burst discarding technique for Deflection Routing to operate effectively even in high traffic load. In a proposed technique, when two bursts compete the same output link, one of the bursts is randomly discarded even when there is an alternate path for Deflection Routing. From the viewpoint of network resource utilization, the discarding probability is calculated from the number of hops which the burst has passed through and the number of the remaining hops to the destination. Computer simulation results show that the Deflection Routing with the proposed system can be effectively operated even in heavy traffic load. |
