摘要 简单介绍了两类基于LAUC的OBS数据信道调度算法--重新调度算法和成组调度算法,分析了其优缺点。分析了在LAUC机制下产生不合理调度的原因,并在此基础上提出了一种新的改进的数据信道调度算法,可以在付出相对较小代价的情况下减少丢包率,提高信道利用率,使信道调度趋于合理。 In this paper, we simply introduced two kinds of data channel scheduling algorithm based on LAUC for OBS first - Re-schedulingand Group scheduling, analyzed their characteristics also. Then by analyzing the cause and the sign of unreasonable scheduling under the mechanism of LAUC, we proposed a new improved data channel scheduling algorithm which can reduce the packet loss rate, yield better bandwidth utilization, and make the channel scheduling reasonable at relatively less cost.
