摘　　要：随着网络的发展和人们对网络服务质量要求的提高,网络计费变得越来越重要,现有计费系统已经不能满足现在网络计费的要求,而基于流量统计的网络计费将成为下一代网络计费的模式。讨论了现有各种主要网络计费方式的原理和应用场合,分析和比较这些计费方式的优缺点。着重描述了因特网记账的需求与流测量的RTFM体系结构,并在此基础上提出了一个基于流量统计的高效的网络计费系统NAS(Network Accounting System)的解决方案。With the network development and service quality demand of network users, network accounting plays a more and more important role in network service. While most of current NASs （ Network Accounting System） do not meet application requirement, NAS based on net-flow statistics will be the next network accounting mode. The current NAS is discussed, their working principle and application situation are axplained. Their advantages and disadvantages are analyzed and compared. The requirement of current network accounting and RTFM framework of network measurement are focused on , and a new and more effective NAS based on RTFM is prompted.
