A preemption scheme, called Resource Consumption Based Preemption (RCBP), is proposed in order to reduce unfairness in an OBS network. In RCBP, the network operator can select any parameters to represent the cost of network resource consumption, and this makes the RCBP flexible to solve complicated fairness problems. We evaluate the performance of the RCBP in reducing unfairness among bursts with different numbers of hops between source and destination in a simulated ring network. The numerical results show that RCBP can enhance fairness in the OBS network.
