VLAN

A VLAN, also called virtual LAN, is a group of hosts that correspond as if they were joined to a broadcast domain.  This allows for the end stations to be put together even if they are not located on the same network.

These devices are actually located in a number of different LAN areas.  This form of technology, which is offered by Cavalier for its business customers, allows departments that are in different locations to be connected to one departmental network.
