Ngokuthuthuka okusheshayo kwamakhompiyutha kanye nobuchwepheshe bawo bokuxhumanisa (okwaziwa nangokuthi “ubuchwepheshe benethiwekhi”), i-Ethernet isiphenduke inethiwekhi yekhompiyutha enezingqimba ezimbili enebanga eliphakeme kakhulu lokungena kuze kube manje.Ingxenye eyinhloko ye-Ethernet iswishi ye-Ethernet.
Ukushintsha okwenziwa ngesandla nohlelo okulawulwayo kusetshenziselwa ukudlulisa amasignali ezwi futhi “ukushintsha isifunda” okudinga imigqa ekhethekile.I-Ethernet inethiwekhi yekhompiyutha edinga ukwabelana ngedatha, ngakho yamukela “ukushintshwa kwephakethe.”Kodwa-ke, kungakhathaliseki ukuthi iyiphi imodi yokushintsha eyamukelwayo, ukushintshwa kuzohlinzeka "ukufinyelela okukhethekile" phakathi kwamaphoyinti amabili.Ngokuqondene nemishini ye-Ethernet, umehluko obalulekile phakathi kwe-switch kanye nehabhu ukuthi uma u-A ethumela umlayezo ku-B, uma udlula kuhabhu, wonke ama-node enethiwekhi afinyelela kuhabhu azothola umlayezo (okungukuthi, ithunyelwe ngendlela yokusakaza), kodwa ikhadi lenethiwekhi lizohlunga ulwazi olungathunyelwanga emshinini wendawo ezingeni lehadiwe;Uma iswishi isetshenziswa, ngaphandle uma u-A ekwazisa ukushintshela ekusakazeni, umlayezo othunyelwe ku-B awusoze watholwa u-C (ngaphandle kokuthola imvume yokulawula ukushintshwa kokuqapha).
Abakhiqizi bokushintshwa kwe-Ethernet bethule ungqimba 3 noma ngisho nokushintsha kwe-4 ngokwesidingo semakethe.Nokho, umsebenzi wayo oyinhloko kusewukushintsha kwephakethe le-Ethernet lesendlalelo sesibili, elinamandla okuphatha isendlalelo se-IP kanye namaphakethe esendlalelo aphezulu.Iswishi yenethiwekhi iyidivayisi yokukhulisa inethiwekhi, ihlinzeka ngezimbobo eziningi zokuxhuma ku-subnetwork ukuxhuma amakhompyutha amaningi.Imakethe yokushintshwa kwenethiwekhi ikhula kancane kancane;ngokuthuthukiswa kwemboni yezokuxhumana kanye nokukhuthazwa kokwaziswa komnotho wezwe, isidingo sokushintshwa kwenethiwekhi sikhula kancane kancane.Inesilinganiso sokusebenza esibiza kakhulu kanye nokuguquguquka okuphezulu, okulula futhi okulula ukukusebenzisa.
Okungenhla incazelo yolwazi ye-Ethernet Switch elethwa yiI-Shenzhen HDV Phoelectron Technology Co., Ltd., Uma ungathanda ukuthola i-Ethernet yokuthengisa eshisayoShintsha, Sicela uvakashele i-ukushintsha kwe-ethernetikhasi.
Imikhiqizo eshiwo ngenhla ingasekela ukulungiselelwa okuhlukahlukene kwenethiwekhi.Ibhizinisi lethu lihlotshiswe ithimba lebhizinisi elinekhono nelichwepheshile ukuze linikeze izinsizakalo zekhwalithi ephezulu ukuze kuboniswane namakhasimende ekuqaleni nomsebenzi wokulandelela, kanye nethimba le-R&D eliqeqeshiwe nelinamandla ukuze lisekele amakhasimende ngobuchwepheshe.
