| 摘 要： | 分析了传统光突发交换中的分组调度算法——LAUC算法的缺陷，提出了一种LAUC算法的改进算法(LAUC-SV算法)，采用自相似业务流模型对两种算法的性能进行了模拟仿真，结果表明在同等条件下LAUC-SV算法下的丢包率比LAUC算法低10^0.5，且新算法下的丢包率关于光纤延时线单元时间的最佳窗口大大展宽，而新算法的复杂度与LAUC算法相比仅呈现线性增长关系．

| Abstract: | The disadvantages of LAUC algorithm in optical burst switch were analyzed. A LAUC SV algorithm was presented. The performance of the two algorithms under self similar traffic model was given and compared. The results showed that the burst loss ratio under the LAUC SV algorithm was 100.5 lower than LAUC algorithm, and the work window about unit time D of fiber delay lines was widened. The complexity of the algorithm was increased linearly compared with LAUC. |
