spoofing
A technique used to reduce network overhead, especially in
{wide area network}s (WAN).
Some network {protocol}s send frequent packets for management
purposes. These can be {routing} updates or {keep-alive}
messages. In a {WAN} this can introduce significant overhead,
due to the typically smaller {bandwidth} of WAN connections.
Spoofing reduces the required bandwidth by having devices,
such as {bridge}s or {router}s, answer for the remote devices.
This fools (spoofs) the {LAN} device into thinking the remote
LAN is still connected, even though it's not. The spoofing
saves the WAN bandwidth, because no packet is ever sent out on
the WAN.
LAN {protocol}s today do not yet accommodate spoofing easily.
