    Iqhaza lokushintshwa kwe-Ethernet

    Isikhathi sokuthumela: Mar-06-2023

    I-Ethernetshintshaluhlobo lweshintshaedlulisa idatha esekelwe ku-Ethernet, futhi i-Ethernet iyindlela yokwabelana ngemidiya yokudlulisa ibhasi. Isakhiwo se-Ethernetshintsha: imbobo ngayinye ye-Ethernetshintshaixhunywe ngokuqondile kumsingathi, futhi ngokuvamile iba kumodi ye-duplex egcwele. Ishintshafuthi ingaxhuma amapheya amaningi ezimbobo ngesikhathi esisodwa, ukuze ipheya ngayinye yabasingathi abaxhumana nomunye nomunye bakwazi ukudlulisa idatha ngaphandle kokungqubuzana. I-Ethernetshintshafuthi isicelo ethandwa 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, iyibhuloho 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, i-full-duplex, neziguquguqukayo. Umgomo we-Ethernetshintsha: I-Ethernetshintshaingumshini 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.
