Network Architectures
There are two types of network architectures: Local Area Network (LAN) and Wide Area Network (WAN).
Each of these types of architecture has various possible configurations. In addition, you will notice that there
are two constants in LAN and WAN network configuration: assigning the IP address for communication
between the controllers and the server by assigning a fixed address or by letting the DHCP server to assign a
dynamic IP address.
We suggest that you carefully read the following section in order to correctly select the scenario that best
matches the environment where you will install the KT-NCC.
Local Area Network (LAN) Architecture
A local network enables users to communicate, exchange data and share resources in an internal network. A
local network can be made up of a server and one or several controllers connected to the server through a
hub or switch.
Whatever the case, an IP address has to be assigned so that the KT-NCC controllers and the EntraPass
server can communicate. When the EntraPass server is used, a static or DHCP address can be assigned to
establish the communication. When the Enterprise server is used, the DHCP server assigns a dynamic IP
address.
Possible LAN Configurations
There are three possible ways of configuring the KT-NCC in EntraPass Global Edition:
•
Static IP Address:
You will use this type of configuration in an environment where the Network
Administrator will determine the IP addresses for communication between the EntraPass server and
the KT-NCC controller. The IP address will be configured using the KT-NCC Web Configuration tool.
•
EntraPass DHCP IP Address
: You will use this type of configuration in an environment where the
EntraPass DHCP server assigns the reserved IP addresses automatically for communication with the
KT-NCC controller(s). The IP address will be configured directly in the EntraPass Global Edition
software.
Note:
You will use the EntraPass DHCP server only when there are no other DHCP servers on the local
network.
•
Enterprise DHCP IP Address
: You will use this type of configuration in an environment where the
Enterprise DHCP server will assign IP addresses automatically for communication with the KT-NCC
controller(s).
Note:
Figure 1 on page 5 shows a LAN architecture with a static IP address; figure 2 shows a LAN
architecture with an EntraPass DHCP server. Figure 3 on page 6 shows a LAN architecture with a
Enterprise DHCP server.
