etwork (
VLAN
) is a group of devices that can be located anywhere
on a network, but all devices in the group have
connection with others as they’re physically
connected together. In other words, VLAN allows end stations to be grouped together even
if they’re not located on the same network switch. With traditional network, users usually
spend a lot of time on devices relocations, but a VLAN reconfiguration can be performed
entirely through software. Also, VLAN provides extra security because devices within a
VLAN group can only communicate with other devices in the same group; for the same
reason, VLAN can help to control network traffic. Traditional network broadcasts data to all
devices, no matter whether they need it or not. By allowing a member to receive data only
from other members in the same VLAN group, VLAN avoids broadcasting and increase
traffic efficiency ( next page, Fig. 2.42).
