|Abstract: ||In this paper, we propose a service differentiated burst transmission called burst-cluster transmission to provide the service differentiation in terms of burst loss for optical burst switching networks. The proposed method consists of burst assembly algorithm and burst transmission scheduling, and it works only at ingress edge node. A mixed timer/burstlength-based assembly algorithm is considered for burst assembly, and bursts with different service classes are assembled simultaneously according to the algorithm. A burst-cluster is generated so that the bursts in the cluster are arranged in order from the lowest priority to the highest one. Then the burst-cluster is transmitted according to the burst transmission scheduling. We also consider the application of the burst-cluster transmission to delay-sensitive traffic. We evaluate by simulation the performance of the burst-cluster transmission for a mesh-torus network. Numerical examples show that the burst-cluster transmission succeeds in providing different service grades even though the burst loss probabilities of high-priority service classes are affected by the traffic load of low priority ones.|
