In this paper, the burst drop policy based on Hop-Count-Factor (HCF) is proposed in the core nodes of OBS networks. The proposed HCF Drop Policy (HCFDP) takes the fairness of the network resources reservation into account and gives the burst with the larger HCF the higher priority in the contention. We also analyze the retransmission scheme in OBS networks theoretically. When HCFDP is combined with...
Owing to the fine-granularity and the separation of control and data plane, OBS technology has the potential to support Grid applications. In this letter, a general analytical model is established to analyze the impacts of the influential factors of both TCP and OBS layers on the performance of Grid-OBS networks ail-roundly. The extensive simulation studies are also conducted. Both the analytical...
TCP performance is analyzed in grid over OBS network with the high bandwidth-delay product scenario. The impacts of the influential factors of both the TCP layer and the OBS layer are analyzed all-roundly.
