    摘要: 網際網路以及行動電話在人們的生活中已經是一個不可或缺的角色,所提供的服務也愈來愈多樣化。對網路服務提供者或是電信業者來說,如何管理廣大的使用者資訊變成一個很大的問題。為了滿足此需求,IETF (Internet Engineering Task Force) 制定了AAA 協定希望能解決這個問題。 移動式IP同樣也是最近熱門的研究項目之一。而在移動式網路內加入AAA伺服器,配合移動式IP之註冊流程與AAA伺服器整合運作,可增加移動式網路的安全性,且可統計使用者所使用的資源並加以計費。 本論文即是探討在將移動式網路與AAA伺服器整合的架構下,AAA伺服器的效能表現。在分析了AAA伺服器的效能後,本論文提出了以兩個較低效能的伺服器來取代原本的AAA伺服器,分別為認證 (Authentication) 伺服器與計費 (Accounting) 伺服器。討論伺服器的服務效能,並以模擬方式探討個別的認證伺服器及計費伺服器在處理效率上之比較。 Internet and mobile phone have played important roles in human’s life. The service provided over them has become more variously. From ISP (Internet Service Provider) and telecommunication operators’ perspectives, how to manage numerous users has become a major problem in the deployment of the Internet. In order to meet this requirement, IETF has proposed AAA protocol to solve the problem. Mobile IP is also a hot research area recently. Adding AAA server into the mobile network and integrating the registration procedures with AAA server can enhance the security of mobile network and even gather the information of resource used by users for charging. In the thesis, performance of the AAA server in an integration of mobile network and AAA mechanism will be examined. After examination of the performance of the AAA server, two lower grade servers model are proposed to replace the original one, they are authentication server and accounting server, respectively. Experimental results for single AAA server and two separate servers (one for authentication and the other one for accounting) are examined through simulation to compare their performance.
