Ukuqonda iziseko zokutshintsha

Kwilizwe lenethiwekhi, ukutshintsha kweSwitches njenge-backBone, ngokufanelekileyo iipakethi zedatha yokuhambahamba kwiindawo ezinenjongo. Ukuqonda iziseko zokutshintsha kokuSebenza kubalulekile ukuze kugxilwe kubunzima bendawo yoyilo yenethiwekhi yanamhlanje.

Ngokuyintloko, i-switch isebenze njengesixhobo sombane esisebenza kwi-Idatha ye-Idatha yeDatha yeModeli ye-OSI. Ngokungafaniyo neeHubs, le ngxelo yosasazo ngokungakhethi phesheya kuzo zonke izixhobo ezixhunyiweyo, ukutshintshiselana kunokuthumela idatha kuphela kwisixhobo esithile kwindawo esiya kuyo, ukuphucula ukusebenza kwenethiwekhi kunye nokhuseleko.

Ukusebenza kwe-switch kuxhomekeke kwizinto ezininzi eziphambili kunye neenkqubo:

Idilesi yedilesi yeMac:
Utshintsho lugcina itheyibhile yedilesi ye-MAC enxibelelanisa iidilesi zeMac kunye namazibuko ahambelana nawo azifundayo. Xa isakhelo sedatha sifika kwizibuko lokutshintsha, ukutshintshwa kukhawulela idilesi ye-MOGO kwaye uhlaziya itafile yayo ngokufanelekileyo. Le nkqubo yenza ukuba iswitshi ukuba lenze izigqibo ezizizo malunga nendawo oza kuzothusa ngayo izakhelo ezilandelayo.
Phambili:
Nje ukuba utshintsho lufunda idilesi ye-MAC yesixhobo esiqhagamshelwe kwizibuko layo, linokudlulisela iifreyimu ngokufanelekileyo. Xa kufika isakhelo, utshintsho lubandakanya itafile yedilesi ye-MAC ukumisela i-portbound efanelekileyo yedilesi ye-MAC. Isakhelo ke sidluliselwe kuphela kuloo mino, sinciphise itrafikhi engafunekiyo kwinethiwekhi.
Usasazo kunye nolwazi olungaziwayo kwiZikhukula:
Ukuba utshintsho lufumana isakhelo sedilesi ye-MAC esingafumaneki kwitheyibhile yedilesi ye-MAC, okanye ukuba isakhelo simiselwe idilesi yosasazo, iswitshi isebenzisa izikhukula. Idlulisela iifreyimu kuzo zonke izibuko ngaphandle kwebuko apho kufike khona isakhelo, uqinisekisa ukuba isakhelo sifikelela kwindawo esihlala kuyo.
IProtokholi yokusombulula idilesi (i-ARP):
Ukutshintshela kudlala indima ebalulekileyo ekuququzelele inkqubo ye-ARP ngaphakathi kwenethiwekhi. Xa isixhobo kufuneka simisele idilesi ye-MAC ehambelana nedilesi ye-IP ethile, isasaza isicelo se-ARP. Ukutshintsha phambili isicelo kuwo onke amazibuko ngaphandle kwesibuko esifunyenweyo, ukuvumela ifowuni inedilesi ye-IP eceliweyo ukuphendula ngqo.
Ii-vhls kunye neeTrunks:
I-Lans ye-Lans (Vlans) ivumela ukutshintsha ukwahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlula-hlulo, ukuphucula intsebenzo kunye nokhuseleko. I-TROnking inceda ukutshintshwa kwendlela yokuthwala kwi-vlans ezininzi ngaphezulu kwekhonkco elinye lomzimba, ukunyusa ukuguquguquka kwinethiwekhi yenethiwekhi kunye noqwalaselo.
Kwisishwankathelo, ukutshintsha kweyonakalisa imbombo yenethiwekhi yanamhlanje, ukuqhuba unxibelelwano olusebenzayo nolukhuselekileyo phakathi kwezixhobo. Ngokuhlala phantsi kwi-insuricacagees yentshukumo yokutshintsha, abalawuli benethiwekhi banokwaphucula intsebenzo, bongeze ukhuseleko, kwaye baqinisekise ukuhamba kwedatha kwinethiwekhi.

I-TODA isebenza ngokuvelisa ukutshintshela kunye nokwakha inethiwekhi yokwakha inethiwekhi kumashishini.
