中文摘要：
光突发交换网络中,数据信道的调度是一个关键问题。文章基于现有的信道资源调度算法,提出了基于优先级的可插空重新调度-PBR-VF（Priority-based Burst Rescheduling with Void Filling）算法,该算法采用LAUC-VF Plus作为子算法,并结合重新调度和优先级选择丢弃机制,能够充分利用信道空隙,对信道资源进行高效调度。仿真结果表明,该算法有效地提高了光突发交换网络的信道资源利用率,同时较好地提供了网络的QoS保证。
英文摘要：
In OBS networks, the data channel scheduling is one of key problems. On the base of the research on traditional scheduling algorithm, the priority-based burst rescheduling with void filling（PBR-VF） algorithm is proposed in this paper.It takes the LAUC-VF Plus algorithm as the sub-algorithm and combines the rescheduling and selective burst dropping strategy. The simulation result shows that, the proposed algorithm can provide better channel resource efficiency and the QoS requirement of optical burst switching networks.
