摘要
介绍了RADIUS,TACACS+和DIAMETER三个提供AAA服务的主要协议的结构,分析其各自特点;根据现在网络的发展对AAA服务的需求,从传输性能、安全性能、漫游代理、主动能力和属性等方面比较、分析RADIUS,TACACS+及DIAMETER协议的优势与不足。研究和分析了DIAMETER协议不仅能满足现有网络的需求,还能满足未来网络发展的需要,是目前公认的较完善的AAA服务协议。
The paper introduces the packet structure of RADIUS,TACACS ＋ and DIAMETER protocols, which provide AAA service, and analyses the characteristics of them separately. According to the requirements of network development for AAA service, author compares and analyses the advantages and limitations of RADIUS, TACACS ＋ and DIAMETER. The study and analysis in the paper shows that DIAMETER protocol could meet not only the requirement of the network, but also the coming development. Now DIAMETER protocol is recognized as the better protocol which provides AAA service .
