CHAPTER 1. Access Point Controller System Overview

The basic W-EP wireless LAN network configuration is a centralized structure where all
the wireless user traffics go through tunneling between APC and W-EP wireless LAN AP.
Therefore, the network information such as subnet information allocated to a wireless user
depends on the configuration of backbone network where the APC is connected.
This provides the following advantages during network configuration and setup.

Installing the APC is just adding it to a legacy data center or backbone network.
Therefore, the possibility of physical change of core network can be reduced.
In addition, separate design of wire/wireless network is easy using the APC as a
boundary.

No dramatic network change is required to install the W-EP wireless LAN AP.
An AP installed in a user area is located in various local network environments in a wide
region. Although it is unavoidable to install or expand a PoE switch, the modification of
local network where wire users are already configured can be minimized.

Because the APC relays all the user traffics, it can restrict a wireless attacker’s effects
and provide differentiated service for each user.
1.4.2 Configuration of Multiple APC for Redundancy
The APC provides the redundancy function to guarantee QoS for various services and
provide service stability in the W-EP environment.
An example of service configuration diagram for redundancy is shown in the below figure.
