Introduction to Portal
Portal authentication, as its name implies, helps control access to the Internet. Portal authentication is
also called web authentication and a website implementing portal authentication is called a portal
website.
With portal authentication, an access device forces all users to log into the portal website at first. Every
user can access the free services provided on the portal website; but to access the Internet, a user must
pass portal authentication on the portal website.
A user can access a known portal website, enter username and password for authentication. This
authentication mode is called active authentication. There is still another authentication mode, namely
forced authentication, in which the access device forces a user trying to access the Internet through
HTTP to log in to a portal website for authentication.
The portal feature provides the flexibility for Internet service providers (ISPs) to manage services. A
portal website can, for example, present advertisements, and deliver community services and
personalized services. In this way, broadband network providers, equipment providers, and content
service providers form an industrial ecological system.
