Abstract

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 the retransmission scheme, the simulation results show that the integrated mechanism can reduce the burst loss rate, decrease the round trip time and improve the throughput of OBS networks.
