I-Gigabit Ethernet (1000 Mbps) iwukuvela kwe-Fast Ethernet (100 Mbps), futhi ingenye yamanethiwekhi angabizi kakhulu amanethiwekhi ahlukahlukene asekhaya namabhizinisi amancane ukuze kuzuzwe ukuxhumana okuzinzile kwenethiwekhi kwamamitha ambalwa.Amaswishi e-Gigabit Ethernet asetshenziswa kakhulu ukukhulisa izinga ledatha lifinyelele cishe ku-1000 Mbps, kuyilapho i-Fast Ethernet isekela isivinini sokudlulisa esingu-10/100 Mbps.Njengenguqulo ephakeme yokushintsha kwe-Ethernet enesivinini esikhulu, amaswishi e-Gigabit Ethernet abaluleke kakhulu ekuxhumeni amadivayisi amaningi njengamakhamera okuphepha, amaphrinta, amaseva, njll. kunethiwekhi yendawo (LAN).
Ngaphezu kwalokho, ukushintshwa kwenethiwekhi ye-gigabit kuyisinqumo esihle kakhulu sabadali bevidiyo nabasingathi begeyimu yevidiyo abadinga amadivayisi anencazelo ephezulu.
I-gigabit switch isebenza kanjani?
Ngokuvamile, ukushintshwa kwe-gigabit kuvumela amadivayisi amaningi ukuthi axhume kunethiwekhi yendawo ngezintambo ze-coaxial, izintambo ezimbili ezisontekile ze-Ethernet, nezintambo ze-fiber optic, futhi isebenzisa ikheli eliyingqayizivele le-MAC ledivayisi ngayinye ukuhlonza idivayisi exhunyiwe lapho ithola uhlaka ngalunye imbobo enikeziwe, ukuze ikwazi ukuhambisa uhlaka ngendlela efanele endaweni oyifunayo.
Iswishi ye-gigabit inesibopho sokuphatha ukugeleza kwedatha phakathi kwayo, amanye amadivayisi axhunyiwe, izinsiza zamafu, ne-inthanethi.Okwamanje lapho idivayisi ixhunywe embotsheni yeswishi yenethiwekhi ye-gigabit, ihlose ukudlulisa idatha engenayo nephumayo kumbobo yokushintsha ye-Ethernet elungile ngokusekelwe embobeni yedivayisi yokuthumela kanye namakheli e-MAC athunyelwayo nendawo okuyiwa kuwo.
Lapho iswishi yenethiwekhi ye-gigabit ithola amaphakethe e-Ethernet, izosebenzisa ithebula lekheli le-MAC ukuze ikhumbule ikheli le-MAC ledivayisi yokuthumela kanye nembobo lapho idivayisi ixhunywe khona.Ukushintsha ubuchwepheshe kuhlola ithebula lekheli le-MAC ukuthola ukuthi ikheli le-MAC lendawo lixhunywe kuswishi efanayo.Uma kunjalo, ukushintsha kwe-Gigabit Ethernet kuyaqhubeka nokudlulisela amaphakethe embobeni eqondiwe.Uma kungenjalo, ukushintshwa kwe-gigabit kuzodlulisela amaphakethe edatha kuzo zonke izimbobo bese ilinda impendulo.Ekugcineni, ngenkathi ilinde impendulo, kucatshangwa ukuthi ukushintshwa kwenethiwekhi ye-gigabit kuxhunywe kudivayisi yendawo, idivayisi izokwamukela amaphakethe wedatha.Uma idivayisi ixhunywe kwenye iswishi ye-gigabit, enye iswishi ye-gigabit izophinda ukusebenza okungenhla kuze kube yilapho uhlaka lufika endaweni efanele.
