| 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。本文在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。

| Abstract: | In order to improve the performance of distinguished network services, it is particularly important to select an appropriate queuing scheduling algorithm. This paper proposed a new scheduling algorithm 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. |
