摘　　要：AAA指的是athentication(认证)、authorization(授权)、accounting(计费)。自网络诞生以来,认证、授权和计费体制就成为其运营的基础。网络中各类资源的使用,需要认证、授权和计费进行管理。在确认用户身份后,根据用户开户时所申请的服务类别,系统可以授予客户相应的权限。最后在用户使用系统资源时,需要有相应的设备来统计用户对资源的占用情况,据此向用户收取相应的费用[1]。论文的主要工作是完成AAA服务器的设计和在RADIUS协议下,设计RADIUS认证/授服务器结构,通过对这种结构的分析及进一步的改进,其测试结果表明服务器结构的设计和实现能够满足流媒体系统实时管理,使得系统计费准确,对系统进行了测试,基本达到研究目的。AAA refers to the athentication （authentication）, authorization （Licensing）, accounting （accounting）. Since the birth of the network, authentication, authorization and accounting system have become the basis of the operation. The use of the resources on network, requires authentication, authorization and accounting to management. Confirm the identity of the user, according to the application when the user service category, system can grant customer permission. Finally, in the use of system resources to the user, need to have the appropriate equipment to statistical occupancy of resource users, according to the user to collect the corresponding costs. The main work of the paper is to complete the AAA server design and in the RADIUS protocol, the EADIUS authentication/ authorized server structure design, through the analysis of the structure and further improvement, the test results show that the design and implementation of streaming media server structure can meet the real time management system, making the system accurate billing carried on the test to the system and reached the purpose of this study.
