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 yi-Ethernetshintsha.
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.” Noma kunjalo, kungakhathaliseki ukuthi iyiphi imodi yokushintsha eyamukelwayo, ishintshaizohlinzeka "ukufinyelela okukhethekile" phakathi kwamaphoyinti amabili. Ngokuqondene nemishini ye-Ethernet, umehluko obalulekile phakathi kweshintshafuthi ihabhu ukuthi uma u-A ethumela umlayezo ku-B, uma udlula kuhabhu, wonke ama-node enethiwekhi afinyelela kuhabhu azothola umlayezo (okungukuthi, uthunyelwa ngendlela yokusakaza), kodwa ikhadi lenethiwekhi lizokwazi hlunga ulwazi olungathunyelwanga emshinini wendawo ezingeni lehadiwe; Uma ishintshaisetshenziswa, ngaphandle uma u-A etshela i-shintshaukusakaza, umlayezo othunyelwe ku-B ngeke uze wamukelwe ngu-C (ngaphandle kokuthola i-shintshalawula imvume yokuqapha).
I-Ethernetshintshaabakhiqizi 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. Inethiwekhishintshaiyidivayisi yokwandisa inethiwekhi, ihlinzeka ngezimbobo zokuxhuma ezengeziwe ze-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-EthernetShintshaelethwe nguI-Shenzhen HDV Phoelectron Technology Co., Ltd., Uma ungathanda ukuthola i-Ethernet yokuthengisa eshisayoShintsha, Sicela uvakashele i-i-ethernetshintshaikhasi.
Imikhiqizo eshiwo ngenhla ingasekela ukulungiselelwa okuhlukahlukene kwenethiwekhi. Ibhizinisi lethu lihlotshiswe ithimba lebhizinisi elinekhono nelichwepheshile ukuze linikeze izinsizakalo zekhwalithi ephezulu ukuze amakhasimende abonisane ekuqaleni nomsebenzi wokulandelela, kanye nethimba le-R&D eliqeqeshiwe nelinamandla ukuze lisekele amakhasimende ngobuchwepheshe.
