Performance Evaluation of Burst Deflection in OBS Networks Using Multi-Topology Routing
This paper evaluates the combination of Optical Burst Switching (OBS) and Multi-Topology (MT) routing. Using MT routing, a source router has a choice of sending IP packets on several different paths to the destination. In OBS networks, deflection may reduce burst loss rate. The authors evaluate a deflection method that is based on MT routing and that ensures that deflected bursts will not loop indefinitely in the network. The performance of the method is evaluated by simulation and compared to two other deflection methods as well as just discarding burst that can not be scheduled.
