摘要
为了找到一种效率较高的宽带网计费方式,分析论述了目前校园网计费的几种模式及其优缺点。针对目前用得最多的计费网关方式对计费网关系统进行了分析,证明了为了提高效率不但要提高硬件性能,特别是网卡的性能,而且最主要的是要精心设计整个计费系统的体系结构。对计费网关的核心部分即数据采集部分提出了底层数据采集、缓冲及双缓冲技术。最后提出了解决方案的实例,详细说明了系统工作的全过程。
To seek an efficient broad band network accounting method, some charge systems and their advantages and disadvantages are analyzed. Gateway accounting system that is widely used today is analyzed and the capability of hardware must be proved to increase, particularly the capability of network card, and the system construction must be seriously designed. The collection of bottom data, buffering and double buffering are analyzed in the part of the collection of data that is the kernel of the accounting system. Finally, a practical example is provided and explained in detail about the whole process.
