Abstract

Channel scheduling is a key technology in Optical Burst Switch network. In conventional sense, BHP (burst header packet) is always processed at the core node once it is received. Compared with these immediate scheduling algorithms, BHP will be delayed to a time window in Group Channel-Schedule Algorithm before it is scheduled. As for the Group-Channel Schedule Algorithm, analysis was made to investigate the influence caused by the schedule time window ▵t on the performance of OBS network. Then comparison is made between the currently used immediate schedule algorithms and the group-schedule algorithm. Evaluation results show that the packet loss performance is improved.
