Ukuqonda iMithetho esisiseko yoTshintsho lokuSebenza

Ehlabathini lothungelwano, utshintsho lusebenza njengomqolo, ngokufanelekileyo ukuhambisa iipakethi zedatha kwiindawo ezijoliswe kuzo. Ukuqonda izinto ezisisiseko zokusebenza kokutshintsha kubalulekile ekubambeni ubunzima boyilo lwale mihla lwenethiwekhi.

Ngokusisiseko, iswitshi isebenza njengesixhobo se-multiport esisebenza kumaleko wekhonkco ledatha yemodeli ye-OSI. Ngokungafaniyo nee-hubs, ezisasaza idatha ngokungenamkhethe kuzo zonke izixhobo eziqhagamshelweyo, iiswitshi zinokuthumela ngobukrelekrele idatha kuphela kwisixhobo esithile kwindawo eya kuyo, ukuphucula ukusebenza kwenethiwekhi kunye nokhuseleko.

Ukusebenza kokutshintsha kuxhomekeke kwizinto ezininzi eziphambili kunye neenkqubo:

Ukufunda idilesi ye-MAC:
Utshintsho lugcina itafile yedilesi ye-MAC enxulumanisa iidilesi ze-MAC kunye namazibuko ahambelana nawo azifundayo. Xa isakhelo sedatha sifika kwindawo yokutshintsha, iswitshi ijonga umthombo wedilesi ye-MAC kwaye ihlaziya itafile yayo ngokufanelekileyo. Le nkqubo yenza ukuba utshintsho lukwazi ukwenza izigqibo ezinolwazi malunga nokuba kuthunyelwe phi izakhelo ezilandelayo.
Phambili:
Nje ukuba iswitshi ifunde idilesi ye-MAC yesixhobo esiqhagamshelwe kwizibuko layo, inokudlulisa izakhelo ngokufanelekileyo. Xa isakhelo sifika, iswitshi idibana netafile yedilesi ye-MAC ukumisela izibuko eliphumayo elifanelekileyo ledilesi ye-MAC ekuyiwa kuyo. Isakhelo sithunyelwa kuphela kwelo zibuko, kuncitshiswa itrafikhi engeyomfuneko kumsebenzi womnatha.
Usasazo kunye nezikhukhula zeunicast ezingaziwayo:
Ukuba utshintsho lufumana isakhelo esinedilesi ye-MAC yokusingwa engafumanekiyo kwitheyibhile yedilesi ye-MAC, okanye ukuba isakhelo silungiselelwe idilesi yosasazo, iswitshi isebenzisa izikhukhula. Ihambisa izakhelo kuwo onke amazibuko ngaphandle kwezibuko apho isakhelo samkelwe khona, iqinisekisa ukuba isakhelo sifikelela kwindawo ekujoliswe kuyo.
Umgaqo weSisombululo seedilesi (ARP):
Iiswitshi zidlala indima ebalulekileyo ekuququzeleleni inkqubo ye-ARP kuthungelwano. Xa isixhobo sifuna ukumisela idilesi ye-MAC ehambelana nedilesi ye-IP ethile, isasaza isicelo se-ARP. Ukutshintshela phambili isicelo kuwo onke amazibuko ngaphandle kwezibuko apho isicelo sifunyenwe, sivumela isixhobo esinedilesi ye-IP eceliweyo ukuba siphendule ngokuthe ngqo.
IiVLAN kunye neziqu:
Ii-LAN ezibonakalayo (i-VLANs) zivumela ukutshintsha ukwahlula inethiwekhi kwiindawo ezahlukeneyo zokusasaza, ukuphucula ukusebenza kunye nokhuseleko. I-Trunking yenza ukuba utshintsho luthwale i-traffic ukusuka kwii-VLAN ezininzi ngaphezu kwekhonkco elilodwa lomzimba, ukwandisa ukuguquguquka kuyilo lwenethiwekhi kunye noqwalaselo.
Isishwankathelo, iiswitshi zenza isiseko sesiseko sothungelwano lwanamhlanje, luququzelela unxibelelwano olusebenzayo nolukhuselekileyo phakathi kwezixhobo. Ngokuphonononga kubuntsonkothi bokusebenza kokutshintsha, abalawuli bothungelwano banokuphucula ukusebenza, baphucule ukhuseleko, kwaye baqinisekise ukuhamba komthungo kwedatha kuyo yonke inethiwekhi.

I-Toda igxile ekuveliseni utshintsho kunye nokwenza ulwakhiwo lwenethiwekhi kumashishini.
