Page "Broadcast domain" Paragraph 8

With a sufficiently sophisticated switch, it is possible to create a network in which the normal notion of a broadcast domain is strictly controlled.

One implementation of this concept is termed a " private VLAN ".

Another implementation is possible with Linux and ebtables.

One helpful analogy is that by creating multiple VLANs, the number of broadcast domains increases, but the size of each broadcast domain size decreases.

This is because a virtual LAN ( or VLAN ) is technically a broadcast domain.
