采用RADIUS协议的AAA系统的研究

Research and implementation of AAA system adopts RADIUS

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采用RADIUS协议。通过对RADIUS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RADIUS协议的可行性。

AAA is authentication., authorization and accounting system, Which is called for the completion of the identification of user identity legitimacy, authority distribution, CDR collection, the cost of clearing, and other functions. The core modules between the Radius server and NAS adopt RADIUS. Through the detailed analysis of RADIUS level of the structure, software structure characteristics, operating principles and accounting process, certify the feasibility which AAA adopts RADIUS, and made some suggestions for improvements.
