摘要: 信道调度算法是提高光突发交换 (OBS) 网络性能的关键技术之一.结合ODBR重调度算法和FDL的延迟作用, 提出来一种Improved-OBDR算法.仿真结果表明改进算法在保证高优先级低丢包率的同时, 保证低优先级尽可能低的丢包率, 提高了资源利用率.Abstract: Channel scheduling algorithm is one of the key technologies on improving the performance of OBS networks. A contention resolution algorithm based on the OBDR rescheduling algorithm and the delay of FDL is proposed in this paper. Simulation shows the Improved-ODBR algorithm can make high priority burst with a low data loss rate and can make low priority burst with a low loss rate at the same time, enhancing the link utilization.
