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.
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.
