| 摘 要： | 针对光纤通道协议中没有规定数据调度算法的问题,在满足系统实时性的情况下,经过对FC-AE-ASM协议的深入分析,提出一种基于令牌桶的优先级和加权轮转相结合的调度算法,同时给出了权值分配和轮转周期的确定方法。在以消息的延迟率作为算法性能的评价指标的基础上,经过仿真,对调度算法的性能进行了验证,结果显示出该算法可以很好地满足航空电子系统实时性要求。

| Abstract: | This paper primarily aim at the problem that it don't have data scheduling algorithm in FC.Through analysis deeply,an algorithm which combine PQ with WRR basing on Token Bucket algorithm is presented,at the same time,include ensured the way of weight distribution and turnaround time. Delay rate is as to the performance of algorithm. Simulation turn out that the scheduling algorithm can meet real-time in avionics system. |

| Keywords: | FC weight distribution turnaround time delay rate |
