HWTACACS接入技术应用研究

Research and Application of HWTACACS Access Technology

AAA是认证、授权、计费系统的简称,用来完成对用户身份合法性的鉴别、权限的分配、话单的采集、费用的结算等功能,其核心模块Radius服务器与网络接入服务器之间的通信协议一般采用RADIUS协议。通过对HWTACACS协议层次结构、软件结构特点、工作原理及认证计费流程的详细分析,验证了AAA系统采用HWTACACS协议的可行性,并通过实例介绍了HWTACACS的应用方法。

AAA is the short form of authentication,authorization and accounting system,used for the completion of the identification of user identity legitimacy,authority distribution,CDR collection,the cost clearing and other functions.The RADIUS protocol is generally adopted for the communication protocol between the core modules the Radius server and NAS.The detailed analysis of HWTACACS protocol structure,software structure characteristics,operating principles and accounting process certifies the feasibility which AAA adopts HWTACACS.The HWTACACS application method is presented with examples.
