2.1 Portal Overview

2.1.1 Introduction to Portal

Portal is also called Portal website. Portal authentication is also called web
authentication. Portal's advantages include:
Users do not need to install a client program.
Powerful ability to support new services: Operators can implement information
inquiry, online shopping and other servers by Portal authentication.
Portal works on this principle: Unauthenticated users can only access the server for
special site. Any other accesses are redirected to a Portal server unconditionally. Users
can access the Internet only after authentication.

2.1.2 Portal System Composition

As shown in Figure 2-1, a Portal system consists of four basic factors: authentication
client, access device, Portal server and authentication/accounting server.
