• Providing absolute QoS differentiation is an important issue in OBS networks. In this paper, we propose a reserve-and-preempt scheme (RPS) to provision best-effort class as much bandwidth as possible while keeping the loss rate of each priority-guaranteed class under its pre-set threshold. Simulation results show that the RPS outperforms existing schemes in terms of the loss rate of best-effort class and bandwidth utilization.
