okanye imodeli yereferensi ye-OSI, umtshintshi usebenza kwinqanaba lesibini lalo mzekelo, i-data link layer.Njengoko kubonisiwe kulo mzobo ulandelayo, iswitshi inamazibuko asibhozo.Xa isixhobo sifakwe kwi-switch nge-RJ45, i-chip master ye-switch iya kuchonga izibuko ezifakwe kwintambo yenethiwekhi, kwaye uqhagamshelwano luphumelele.Idilesi ye-mac yesixhobo esiqhagamshelweyo yenye-to-enye ehambelana nezibuko.Xa zonke iizibuko ezisibhozo zixhunyiwe, inkosi yangaphakathi inokwenza itafile ye-MAC kunye nawo onke amachweba.Kunxibelelwano olulandelayo lwezibuko, xa isixhobo sihambisa ulwazi, siya kuvelisa ipakethi yedatha ene-source mac kunye nethagethi ye-mac.Emva kokuba ipakethe yedatha ifikelele kulawulo oluphambili, inokuthumela ngokukhawuleza ipakethe yedatha kwisixhobo kunye nedilesi ye-mac ehambelanayo ngetafile esekiweyo ye-mac, ukuze kufezekiswe unxibelelwano phakathi kwezixhobo.Ukongeza, iipakethi ezithunyelwe kwidilesi ye-MAC ziya kuthunyelwa kuphela kumachweba ahambelanayo, kungekhona onke amachweba.Ngoko ke, ukutshintshwa kungasetyenziselwa ukwahlula ikhonkco yedatha yosasazo losasazo, oko kukuthi, i-domain yengxabano, kodwa ayikwazi ukwahlula i-network layer broadcast, oko kukuthi, i-domain yosasazo.
Tutshintshe une-high-bandwidth back ibhasi kunye ne-matrix yokutshintsha kwangaphakathi.Zonke izibuko zokutshintsha zincanyathiselwe kule bhasi ngasemva.Emva kokuba isiphaluka solawulo sifumana ipakethe yedatha, i-port yokucubungula iya kukhangela itafile yokuthelekisa idilesi kwimemori ukuze inqume ukuba yiyiphi i-port ye-NIC (ikhadi lenethiwekhi) yendawo yokuya kuyo i-MAC (idilesi ye-hardware yekhadi lenethiwekhi) eqhotyoshelwe kuyo.Ipakethi yedatha iya kuthunyelwa ngokukhawuleza kwi-port yendawo nge-matrix yotshintshiselwano lwangaphakathi.Ukuba i-MAC yendawo ayikho, iya kusasazwa kuwo onke amachweba, Emva kokufumana impendulo yechweba, utshintshiselwano luya "kufunda" idilesi entsha ye-MAC kwaye yongeze kwitafile yedilesi ye-MAC yangaphakathi.Umtshintshi unakho "ukwahlula" inethiwekhi.Umtshintshi uvumela kuphela i-traffic yenethiwekhi eyimfuneko ukuba idlule kwitshintshi ngokuyithelekisa netafile yedilesi ye-IP.Ngokusefa kokutshintsha kunye nogqithiso, ummandla wongquzulwano unokunqunyulwa ukuya kubungakanani obulawulekayo.
Oku ngasentla yinkcazo yomgaqo wokusebenza wokutshintsha okunikezelwe nguShenzhen HDV Phoelectron Technology Co., Ltd.ndiyathemba ukuba eli nqaku linokukunceda ukwandisa ulwazi lwakho.Ngaphandle kweli nqaku ukuba ujonge inkampani elungileyo yomenzi wezixhobo zonxibelelwano lwefiber onokuthi uyithathele ingqalelongathi.
