spoofing
A technique used to reduce network overhead, especially in wide area networks
(WAN).
Some network protocols 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 bridges or
routers, 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 protocols today do not yet accommodate spoofing easily.
