基于Linux的TCP/IP网络计费管理的研究

本文讨论了在Ｌｉｎｕｘ操作系统下基于ＳＮＭＰ协议的网络计费管理系统的实现方法，利用ＳＮＭＰ实现了网络流量数据的采集，通过Ｃｉｓｃｏ路由器的远程访问控制系统记录拔号上网用户的连接时间和端口号。采用面向对象的关系数据库管理系统ＰｏｓｔｇｒｅｓＳＱＬ语言，设计了网络计费信息的处理，查询和管理等功能，从而实现了 种低成本的网络计费解决方案。

RESEARCH ON TCP/IP NETWORK ACCOUNTING BASED ON LINUX

This paper discusses a method to realize the network a cc ounting management system on the base of SNMP in the Linux operating system. SNM P is used to gather the flux data on the network, and the dial-up user's connec ting time together with its port number are also recorded through the remote vis iting control system of Cisco Router (XTACACS). By the use of object oriented RD BMS Postgres SQL, we designed in the system the functions about the treatment, i nquiry and management of the accounting information on the network, and have rea lized the possibility of network accounting management system at low cost.
