Definitions of SPOOFING
Sort: Oldest first
A technique used to reduce network overhead, especially inwide area networks (WAN).Some network protocols send frequent packets for managementpurposes. These can be routing updates or keep-alivemessages. 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 remoteLAN is still connected, even though it's not. The spoofingsaves the WAN bandwidth, because no packet is ever sent out onthe WAN.LAN protocols today do not yet accommodate spoofing easily.["Network Spoofing" by Jeffrey Fritz, BYTE, December 1994,pages 221 - 224].
