本文讨论了在 L inux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 (XTACACS)记录拨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 Postgres SQL语言 ,设计了网络计费信息的处理、查询和管理等功能 .从而实现了一种低成本的网络计费解决方案
This paper discusses how to realize the network charging management system based on SNMP protocol under Linux operating system.It uses SNMP to collect the network traffic data and record the connection time of dial-up users through the remote access control system (XTACACS) of Cisco router And port number.It uses the object-oriented relational database management system Postgres SQL language to design the functions of processing, inquiry and management of network charging information, so as to realize a low-cost network charging solution
