一种虚拟AAA服务器实现方法的研究与实现

摘要

In order to solve the problem that uses an existing AAA server equipment to simulate multiple logical AAA servers,studied a kind of implementation method of virtual AAA server based on application and analysis of the concept of virtual device in AAA server, and provided a specific software design and structure modules composition for virtual AAA server on the basis of introducing the princi-ple. Finally,two virtual AAA server were simulated based on an existing AAA equipment under laboratory conditions by the method pro-posed,providing services to two different access networks at the same time. Experimental results show that the method to implement virtu-al AAA server is completely feasible and effective.%为了解决利用已有的一套AAA服务器设备虚拟出多个不同的逻辑AAA设备的问题，文中把虚拟设备的概念在AAA服务器上进行应用分析，研究了一种虚拟AAA服务器的实现方法，并在介绍原理的基础上给出了具体的虚拟AAA服务器的软件设计和结构模块组成。最后，利用文中介绍的方法，在实验室条件下，成功地在一套AAA设备上虚拟出了两套逻辑上完全独立的AAA服务器，为不同的网络接入提供服务。验证结果表明，文中研究和探讨的实现虚拟AAA服务器的方法是完全可行和有效的。
