| Abstract: | At first, the definition of AAA and the basic model for AAA service are introduced. Then, the characteristics of new Internet applications, such as Mobile-IP, ROAMREQ and NASREQ, and their requirements for AAA service are described. And the limitations and disadvantages of current AAA protocols, RADIUS and TACACS , are also set out. At last, Diameter protocol is introduced, which will provide AAA service for the Internet in the future. |
