摘要 在分组网络设备中,采用适当的调度算法是为网络上运行的业务提供服务质量(QoS:quality of service)的关键。在差额循环(DRR:deficit round robin)调度算法的基础上提出了一种动态差额循环(D-DRR:dynamic deficit round robin)调度算法,该算法通过实时跟踪特定服务队列长度来调整量子值,以改变预约带宽,从而满足一些特定的实时业务类型的QoS。 A novel fair queuing algorithm D-DRR(dynamic deficit round robin)is proposed in this paper. This algorithm can change the bandwidth by adjusting the quantum according to the latest length of the queue, so it can provide the QoS(quality of service) for the real time services.
