摘　　要：目前网络用户非常关心其所上缴的费用是否能对应自己获得的性能服务。在交换节点处实施的调度算法是解决这个问题的重要手段之一。现实的网络背景环境决定了在核心网节点处的调度算法需满足数据流数目多、流量大的要求,而且应使得用户上缴费用与其所获得的服务性能大致成线性关系。根据这个重要的思想对交换节点处的调度算法进行研究设计以及进行初步的仿真验证。Network consumers want to know whether their money paying to ISP corresponds to the performance they receive. The scheduling arithmetic implemented in switching node is one of the important instruments to solve this problem. Actual network background decides that the scheduling arithmetic implemented in core network switching node must accord with the features that there are immense numbers of flows and huge flux. Except it, we also hope that the relation between users＇ paying money and their receiving performance can be linearity. Based on these, we do a research on scheduling arithmetic and do a simulation to validate it.
