A technique used to reduce network overhead, especially in
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.
