摘要 AFDX交换机的静态优先级非抢占式队列调度(SPUS)算法不能消除输出分组中的随机抖动。为此,采用将虚拟时钟作为分组调度发放合法时间的方法对SPUS算法进行改进。在发往级联端口的分组输出之前,先经过整形调度使数据流均匀地输出,以确保交换机的服务质量。仿真结果表明,改进后的算法可消除输出分组随机抖动,适用于交换机级联端口。 Aiming at the shortage of AFDX switch's Static Priority Un-interrupt Scheduling(SPUS) algorithm in eliminating output random jitter, Virtual Clock(VC) is added to provide legitimate time in packet schedule for ameliorating the algorithm. Packets sending to cascading port enters shaping scheduling before output queue. Shaping scheduling maintains the switch's certainty and quality of service. Simulation results show that the algorithm after ameliorating can eliminate output random jitter, which beseems to switch's cascaded port.
