Ukushintsha kwenethiwekhi eyindandatho kusebenza kungqimba yesixhumanisi sedatha, ngebhasi elibuyela emuva elinomkhawulokudonsa ophezulu kanye ne-matrix yokushintsha yangaphakathi.Ngemuva kokuthi isifunda sokulawula sithole iphakethe ledatha, imbobo yokucubungula ibheka ithebula lereferensi yekheli kumemori ukuze inqume ukuthi iyiphi imbobo ikhadi lenethiwekhi (ikhadi lenethiwekhi) le-MAC eqondiwe (ikheli lehadiwe yekhadi lenethiwekhi) exhunywe kuyo.Amaphakethe edatha adluliselwa ngokushesha endaweni okuyiwa kuyo nge-matrix yokushintsha yangaphakathi.Uma i-MAC eqondiwe ingekho, izosakazwa kuzo zonke izimbobo.Ngemva kokuthola impendulo yembobo, inkinobho yenethiwekhi yokukhala "izofunda" ikheli elisha le-MAC futhi ilingeze kuthebula lekheli langaphakathi le-MAC.Kungenzeka futhi ukusebenzisa amaswishi enethiwekhi yokukhala "ukuhlukanisa" inethiwekhi.Ngokuqhathanisa ithebula lekheli le-IP, ukushintsha kwenethiwekhi yenethiwekhi kuvumela kuphela ithrafikhi yenethiwekhi edingekayo ukuthi idlule ekushintshanisweni kwenethiwekhi yendandatho. Ngokuhlunga nokudlulisa inkinobho yenethiwekhi yendandatho, isizinda sokushayisana singancishiswa ngempumelelo, kodwa ukusakazwa kwesendlalelo senethiwekhi akukwazi ukuncishiswa. ihlukaniswe, okungukuthi, isizinda sokusakaza.

Imbobo yokushintsha iluphu.I-loop switch ingadlulisela idatha phakathi kwamapheya embobo amaningi ngesikhathi esisodwa.Imbobo ngayinye ingathathwa njengengxenye yenethiwekhi ebonakalayo ehlukile (Qaphela: ingxenye yenethiwekhi engeyona eye-IP).Amadivayisi enethiwekhi axhunywe kuyo angajabulela yonke i-bandwidth ngaphandle kokuncintisana namanye amadivaysi.Lapho i-node A ithumela idatha ku-node D, i-node B ingathumela idatha ku-node C ngesikhathi esifanayo, futhi ama-node womabili ajabulela wonke umkhawulokudonsa wenethiwekhi futhi abe nawo. okungokwakhe ukuxhumana okubonakalayo.Uma kusetshenziswa iswishi yenethiwekhi yeringi ye-Ethernet engu-10Mbps, ukugeleza okuphelele kweswishi yenethiwekhi yeringi kuyalingana no-2*10Mbps=20Mbps.Uma kusetshenziswa ihabhu eyabelwe engu-10Mbps, ukugeleza okuphelele kwehabhu akudluli ku-10Mbps. Ngamafuphi, ukushintshwa kokukhala kuyidivayisi yenethiwekhi esekelwe ekuhlonzeni ikheli le-MAC, engaqedela imisebenzi yokuhlanganisa nokudlulisela phambili amafreyimu wedatha.Iswishi yokukhala ingakwazi “ukufunda” ikheli le-MAC futhi iligcine kuthebula lekheli langaphakathi.Ngokusungula indlela yokushintsha yesikhashana phakathi komqalisi nomamukeli oqondiwe wohlaka lwedatha, uhlaka lwedatha lungafinyelela ngokuqondile ekhelini eliqondiwe lisuka ekhelini lomthombo.

Idrayivu yokushintsha indandatho.Imodi yokudlulisa yeswishi yeringi i-full-duplex, half-duplex, full-duplex/half-duplex adaptive.I-duplex egcwele yeswishi yenethiwekhi yeringi isho ukuthi iswishi yenethiwekhi yokukhala ingathola idatha ngenkathi ithumela idatha.Lezi zinqubo ezimbili ziyavumelaniswa, njengoba sivame ukusho, singakwazi ukuzwa izwi lomunye nomunye lapho sikhuluma.Wonke amaswishi eringi asekela i-duplex egcwele.Izinzuzo ze-duplex egcwele ukubambezeleka okuncane kanye nesivinini esisheshayo.

Uma sikhuluma nge-full-duplex, asikwazi ukuziba omunye umqondo ohlobene kakhulu nayo, okungukuthi, “half-duplex.”Okubizwa ngokuthi i-half-duplex kusho ukuthi isenzo esisodwa kuphela esenzeka esikhathini esithile.Isibonelo, umgwaqo omncane ungadlula imoto eyodwa kuphela ngesikhathi esisodwa.Uma izimoto ezimbili zishayela zibheke ezinhlangothini eziphambene, kungathathwa isinyathelo esisodwa kuphela kulokhu.Lesi sibonelo sibonisa umgomo we-half-duplex.Ama-walkie-talkies okuqala kanye nama-hubs okuqala kwakuyimikhiqizo eyi-half-duplex.Ngokuthuthuka okuqhubekayo kobuchwepheshe, inyunyana ephindwe kabili kancane kancane yahoxa esigabeni somlando.
