摘　　要：针对目前校园网的计费需求以及常用的两种计费方式的缺陷,提出了一种基于Linux的Netfilter框架的计费系统解决方案,并对数据处理过程中的一系列策略问题进行了理论分析和实验比较。通过在Linux内核级设置过滤器,优化过滤规则,实现了一种适应性广、稳定性强、高效的网关计费系统。A new scheme of network accounting system is introduce, which is based on the Netfilter framework of the Linux. Depending on the requirement of the campus network and the shortages of two existing accounting modes, a series of strategic problems on the data processing in the aspect of theory and experiment are analyzed. Then a high performance gateway accounting system is provided, which has features in the extensive applicability, the strong stability by using the filter in the Linux kernel and the optimal rules of the filter.
