The Subscriber Interface 177
The AAA Structure
The AG-2000w’s Authentication, Authorization, and Accounting (AAA) module
enables the solution provider to provision, track, and bill new or returning
subscribers. This includes:
‹
Allowing the solution provider to bill for the high speed network services it
provides, track usage on the network, and deny service to those guests who
have not paid.
‹
Allowing the solution provider to bill subscribers for services rendered,
either directly to the subscriber, via a mailed invoice, or directly to the
subscriber’s credit card account.
The Authentication module is responsible for ensuring that when subscribers log in to
the system they are correctly identified. It can identify subscribers in many different
ways. For example:
‹
Based on their hardware (MAC) address.
‹
By validating their user name and password.
‹
By looking up subscribers on a local (flash) database.
‹
By looking up subscribers on a remote database.
The initial login page can be presented in various ways, depending on the system’s
configuration. The AG-2000w supports any of the following methods and tools:
‹
Internal and external Web pages.
‹
External “portal” page for redirection.
‹
User name and MAC-based logins (simultaneous or stand-alone).
‹
User-selectable options and parameters (for example, defining the time
purchased).
Only subscribers that are correctly identified and authenticated are authorized to
access the system. Once authorized, the subscriber’s activity is logged and billed
through the AG-2000w’s Accounting module.
The Accounting module fully supports the following functions:
‹
Credit card billing (for example, interaction with AuthorizeNet ).
‹
User name and password verification.
‹
Billing verification.
The Authentication module can support user name and MAC address
authentication simultaneously.
