3. System Overview
3.1. System Concept
If you have experienced other LevelOne WLAN WHG Controller products before and are familiar with its system
concept, you may skip the concept description below.
Please proceed to the next section on (Getting Started).
WHG Controller is capable of managing user authentication, authorization and accounting (AAA). The user account
information is stored in the local database or a specified external database server. Featured with user authentication
and integrated with external payment gateway, WHG Controllers allows users to easily pay the fee and enjoy the
Internet service using credit cards through Authorize.Net, PayPal, SecurePay, or WorldPay.
With centralized AP management feature, the administrator does not need to worry about how to manage multiple
wireless access point devices. WHG Controllers and LevelOne APs combined provides flexible network solution
which supports overlay deployment where traffics from remote sites are tunnelled back and centrally controlled by
WHG Controller.
Furthermore, WHG Controller introduces the concept of Service Zones - multiple virtual networks, each with its own
definable access control profiles. This is very useful for hotspot owners seeking to provide different customers or
staff with different levels of network services.
The following portion of this section explains the basic concepts of WHG Controller. With the understanding of these
concepts, the administrator will be able to do more advanced network planning and to manipulate the configurations
of WHG Controller to suit his own specific application. It is sufficient for most of administrators to use the default
configuration with minor WAN/DNS address changes for simple deployments.
Gateway
is a network node where a small network attaches to a bigger network. WHG Controller is a kind of
gateway in a network environment; hence it has those features a typical gateway has, such as NAT, DHCP, DMZ,
Firewall and etc. Conventionally, the bigger network is referred as the gateway’s
WAN side
or upstream network,
while the small network is referred as the gateway’s
LAN side
. The Ethernet ports leading to the WAN side network
is called
WAN ports
. The Ethernet ports leading to the LAN side network is called
LAN ports
.
Local User
is a type of user with its account credential stored in a built-in database named “Local” within WHG
Controller. The WHG Controller’s “Local” database capacity varies with different model. A local user account does
not have an expiration date once they are created. If administrator wishes to terminate the account, he must remove
it manually from the database. A local database can be used as an external RADIUS database for another WHG
Controller product for account roaming.
On-demand User
is a type of user with its account credential stored in a built-in database named “On-demand”
within WHG Controller. The WHG Controller’s “On-demand” database capacity varies with different model..
On-demand User is used for short term usage purpose; it has an expiration period. An on-demand account record
will be recycled for creating new on-demand account if it has expired for over 15 days or has been deleted by the
