摘要
针对下一代通讯网络EPC(Evolved Packet Corenetwork)系统中AAA服务器通信协议的特点:同时支持Radius协议和Diameter协议,为了解决AAA对不同协议的兼容和自动翻译问题,文中设计和实现了一种基于Radius/Diameter双协议栈的用于下一代通讯网络EPC系统中的AAA服务器。通过采用协议适配与转换模块、Radius协议栈模块、Diameter协议栈模块等,经过简单的配置,AAA服务器即可自动完成不同协议的翻译和转换。实验结果表明,这种支持双栈架构的下一代AAA服务器,能够很好地兼容不同的协议,并有效降低了工程维护成本。
For the characteristics of the communication protocol of the AAA server in the next-generation communications networks EPC system：To support Radius protocol and Diameter protocol simultaneously,in order to solve problem of compatibility and automatic trans-lation between different protocols,designed and implemented a AAA server based on Radius/ Diameter dual-stack for next-generation communications networks EPC system. By using protocol adaptation and conversion module, Radius protocol stack modules, Diameter protocol stack module etc. ,through simple configuration,AAA server can automatically complete the translation and conversion of differ-ent protocols. Experimental results show that this support dual-stack architecture of the next generation of AAA server can be well com-patible with different protocols,and effectively reduce engineering and maintenance costs.
