I-Ethernet switch iwuhlobo lokushintshwa oludlulisa idatha ngokusekelwe ku-Ethernet, futhi i-Ethernet iyindlela yokwabelana ngemidiya yokudlulisa ibhasi.Isakhiwo sokushintsha kwe-Ethernet: imbobo ngayinye yeswishi ye-Ethernet ixhunywe ngokuqondile kumsingathi, futhi ngokuvamile iba kumodi ye-duplex egcwele.Iswishi ingaphinda ixhume amapheya amaningi ezimbobo ngesikhathi esisodwa, ukuze ipheya ngayinye yabasingathi abaxhumanayo bakwazi ukudlulisa idatha ngaphandle kokungqubuzana.I-Ethernet switch nayo iwuhlelo lokusebenza oludume kakhulu, futhi intengo ishibhile.Ngakho-ke, inkambu yesicelo ibanzi kakhulu, futhi ukushintshwa kwe-Ethernet kungabonakala kuma-LAN amakhulu namancane.Amaswishi e-Ethernet ngokuvamile anezimbobo ezimbalwa ukuya kweziningi.Empeleni, ibhuloho lenethiwekhi enezimbobo eziningi.Ngaphezu kwalokho, izinga layo lechweba lingahluka, futhi imodi yayo yokusebenza ingase ihluke, njengokuhlinzeka ngomkhawulokudonsa ongu-10M no-100M, ukuhlinzeka ngezindlela zokusebenza eziyisi-half-duplex, ezigcwele-duplex, neziguquguqukayo.Umgomo weswishi ye-Ethernet: Iswishi ye-Ethernet ingumshini osesendlaleni sesixhumanisi sedatha.I-Ethernet isebenzisa ikheli lendawo (ikheli le-MAC), amabhithi angu-48, namabhayithi angu-6.Umgomo wayo wokusebenza ukuthi uma uhlaka lokusakaza lwamukelwe, luzoludlulisela kuwo wonke amachweba ngaphandle kwembobo eyamukelayo.Uma uhlaka lwe-unicast lwamukelwe, hlola ikheli lalapho luya khona futhi lihambisana nethebula lekheli lalo le-MAC.Uma kukhona ikheli lendawo, lizodluliselwa phambili.Uma ingekho, izogcwala amanzi (ukusakazwa).Ngemva kokusakaza, uma engekho umsingathi okheli lakhe le-MAC lifana nekheli le-MAC okuyiwa kulo lohlaka, lizolahlwa.Uma kukhona umsingathi ikheli lakhe le-MAC elifanayo, lizongezwa ngokuzenzakalelayo kuthebula lekheli le-MAC.
