The network application becomes more extensive in recent years, the sharing and transmission of information and unrestricted visiting to the network have led to the problem of information safety. The AAA (authentication, authorization, accounting) system based on the collaboration of Radius (Remote Authentication Dial In User Service ) protocol and NAS (network access server) can effectively solve those problems above.The Grid Computing, which is the third generation of Internet, can accomplish the overall sharing of resources of the network . Because it has the virtues of the distribution and parallel computation, it becomes the focus of academia and business application . Its remarkable characters are distributed, shared , similar, dynamical, variety , autonomy and the multiple in management. These characters are needed for multiple network services at present.With the development of the Grid Computing, the Mobile Agent becomes activable. The features of Mobile Agent, including independence , transplanting, responding the change dynamically, supporting fault-tolerant calculation, serving the characteristic of customizing , saving the network communication expenses and alleviating the calculation pressure of the end of the server etc, are fit for the need of Grid Computintg .This paper has proposed a Grid Computing model based on Mobile Agent, and applies this model to AAA system.This paper proposes a network service system, named AAA system, based on the Radius protocol. The paper describes the topological structure of network of this system, systematic level model, working course and the analysis of each function module which is designed in the key module Radius Server of system. And it explains the main function interfaces of the message queue and Radius Server. Then this paper proposes a Grid Computing model based on Mobile Agent to make up the shortcoming in the system in the parallel computing aspect .The paper has explained the relevant theories about the Grid Computing and Mobile Agent. This paper proposes the whole frame , procedure of the system , task scheduling to this model ,etc and gives a performance comment. Finally the paper draws a conclusionabout the whole paper and shows the future research work.
