spoofing 音标拼音: [sp'ufɪŋ] n. 电子欺骗 电子欺骗 45 Moby Thesaurus words for "spoofing": bamboozlement, befooling, bluffing, calculated deception, circumvention, conning, deceiving, deception, deceptiveness, defrauding, delusion, delusiveness, dupery, enmeshment, ensnarement, entanglement, entrapment, fallaciousness, fallacy, falseness, flimflam, flimflammery, fond illusion, fooling, hallucination, hoodwinking, illusion, kidding, mirage, outwitting, overreaching, phantasm, putting on, self-deception, snow job, song and dance, spoofery, subterfuge, swindling, trickiness, tricking, victimization, vision, willful misconception, wishful thinking 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. ["Network Spoofing" by Jeffrey Fritz, BYTE, December 1994, pages 221 - 224]. (1995-01-13)
