摘要
为了提高网络区分服务的性能,选择一个合适的队列调度算法尤为重要。在WRR调度算法的基础上提出了一种新的调度算法p-VDWRR(Priority Variable Deficit Weighted Round Robin),P-VDWRR不仅能够提供一定的QoS(Quality of Service)保证,还能够在一定范围内根据网络负载情况动态分配网络资源,降低网络节点的丢包率。
In order to improve the performance of distinguished network services,it is particularly important to select an appropriate queuing scheduling algorithm.A new scheduling algorithm is proposed based on the WRR, whose name is Priority Variable Deficit Weighted Round Robin(P-VDWRR).P-VDWRR could provide certain assurance of the QoS,distribute the network resources dynamically according to the load situation within a certain range and reduce the packet loss rate of network nodes.
