网吧认证计费管理系统的设计与实现

Design and realization of the management system for authentication and accounting of Internet cafe

对宽带IP网建设与发展过程中产生的多种认证与计费的前沿技术进行分析、比较和研究,提出了基于PPPoE等协议对网吧授权、认证、计费、监控管理系统的开发方案。该系统在数据链路层采用PPPoE协议,通过PPPoE拨号对用户身份进行认证;在网络层使用路由器实时采集数据,对用户按规定进行计费;并与服务器上的AAA(Authorize-Authenticate-Account)软件技术相结合,解决了上网用户授权、身份认证、时长/内容计费、营业状态管理等宽带IP网络应用过程中面临的核心问题。本系统由四个子系统组成,分别是:管理端代理端子系统、认证计费子系统、网吧前台子系统、网吧客户端子系统。

This article analysed ,compared and studied many kinds of oneup technology of authentication and accounting which had been brought out during the construction and development of broadband IP network, and brought forward a developing scheme to authorize, authenticate, account and monitor the Internet cafe based on protocols,such as PPPoE,etc. This system authenticate the user by dialing with PPPoE protocol in datalink layer ,and collect data of accounting on realtime by router in network layer , and combine with AAA software on the server to solve the kerneled problem, such as authorizing authentication, accounting ,opening state,etc. This system was made up of four subsystem: managment and proxy subsystem, authentication accouning subsystem, Internet cafe frontdesk subsystem and customer and subsystem.
