摘　　要：随着IP技术和Internet技术的发展,网络系统中对于认证、授权、计费(AAA)的要求也越来越复杂。传统的认证协议已经无法满足未来网络的需求,为此IETF针对此问题提出并逐渐完善Diameter协议作为下一代AAA的标准协议。简要介绍了Diameter协议的结构特点和一般的AAA系统模型,设计了一个简单的基于Diameter协议的AAA模型,并详细说明了Diameter协议的实现流程。With the development of IP and Intemet technique, the requirements of AAA（Authentication, Authorization and Accounting）in network system become more and more complex, which are already beyond the designed ability of traditional AAA protocols. To solve this problem, IETF has put forward the Diameter pretoeol to substitute the traditional AAA pretoeol as the standard of next generation of AAA pretoeol.This paper introduces the structure and features of Diameter Protocol and a general AAA system model in brief. To explain the operational principle of Diameter Protocol in detail, the author designs and implements a simple AAA model based on Diameter Protocol.
