Cost-Based Burst Dropping Strategy in Optical Burst Switching Networks

Overview Optical Burst Switching (OBS) is a new paradigm for future all-optical networks. Intentional burst dropping is one of techniques used to achieve desired quality of service. This paper notes that some bursts are more likely to cause contention. The paper proposes a cost function that can be used to predict the likelihood that a given burst will interfere with other traffic, then the paper explains how, by using this information a new burst dropping strategy can be designed. The paper compares the method with a random burst dropping technique and show that the cost-based approach offers a significant performance improvement.
