Kuthungelwano, ukuqonda umahluko phakathi kweLayer 2 kunye neLayer 3 switching kubalulekile ekuyileni isiseko esisebenzayo. Zombini iintlobo zokutshintsha zinemisebenzi ephambili, kodwa zisetyenziswa kwiimeko ezahlukeneyo ngokuxhomekeke kwiimfuno zenethiwekhi. Makhe sihlolisise iiyantlukwano kunye nezicelo.
Yintoni ukuTshintsho kwiLayer 2?
Ukutshintshwa kwe-Layer 2 kusebenza kwiNqanaba yeDatha yemodeli ye-OSI. Ijolise ekuthumeleni idatha ngaphakathi kwenethiwekhi yendawo yendawo enye (LAN) ngokusebenzisa iidilesi ze-MAC ukuchonga izixhobo.
Iimpawu eziphambili zokutshintsha kweLayer 2:
Sebenzisa idilesi ye-MAC ukuthumela idatha kwisixhobo esichanekileyo ngaphakathi kwe-LAN.
Zonke izixhobo zivame ukuvunyelwa ukuba zinxibelelane ngokukhululekileyo, ezisebenza kakuhle kuthungelwano oluncinci kodwa lunokubangela ukuxinana kwiisetingi ezinkulu.
Inkxaso ye-Virtual Local Area Networks (VLANs) yokwahlulwa kwenethiwekhi, ukuphucula ukusebenza kunye nokhuseleko.
Iiswitshi zeLayer 2 zilungele uthungelwano oluncinci olungadingi buchule bokuhamba phambili.
Yintoni ukuTshintsho kwiLayer 3?
Ukutshintshwa kwe-Layer 3 idibanisa ukuhanjiswa kwedatha ye-switch ye-2 ye-2 kunye nekhono lokuhambisa le-network layer ye-OSI model. Isebenzisa iidilesi ze-IP ukuhambisa idatha phakathi kweenethiwekhi ezahlukeneyo okanye ii-subnets.
Iimpawu eziphambili zokutshintsha kweLayer 3:
Unxibelelwano phakathi kwamanethiwekhi azimeleyo lufezekiswa ngokuhlalutya iidilesi ze-IP.
Phucula ukusebenza kwiindawo ezinkulu ngokwahlula inethiwekhi yakho ukunciphisa ugqithiso lwedatha olungeyomfuneko.
Iindlela zedatha zinokulungiswa ngokuguquguqukayo kusetyenziswa iiprothokholi zomzila ezifana ne-OSPF, i-RIP, okanye i-EIGRP.
Utshintsho lweLayer 3 luhlala lusetyenziswa kwiindawo zeshishini apho iiVLAN ezininzi okanye ii-subnets kufuneka zisebenze.
Umaleko 2 vs. Umaleko 3: Umahluko ongundoqo
Ukutshintsha kwe-Layer 2 kusebenza kwi-data link layer kwaye isetyenziselwa ngokuyinhloko ukudlulisa idatha ngaphakathi kwenethiwekhi enye esekelwe kwidilesi ye-MAC. Zilungele iinethiwekhi ezincinci zendawo. Ukutshintsha kweLayer 3, kwelinye icala, sebenza kumaleko wothungelwano kwaye usebenzise iidilesi ze-IP ukuhambisa idatha phakathi kwenethiwekhi ezahlukeneyo. Oku kubenza babe lolona khetho lubalaseleyo kwimo yenethiwekhi enkulu, entsonkothileyo ngakumbi efuna unxibelelwano phakathi kwee-subnets okanye iiVLAN.
Eyiphi Ofanele Uyikhethe?
Ukuba inethiwekhi yakho ilula kwaye yenziwe yasekhaya, iLayer 2 switch ibonelela ngexabiso elisebenzayo kunye nokusebenza ngokuthe ngqo. Kuthungelwano olukhulu okanye iimeko-bume ezifuna ukusebenzisana kuzo zonke ii-VLAN, iswitshi yeLayer 3 lolona khetho lufanelekileyo.
Ukukhetha iswitshi echanekileyo kuqinisekisa ugqithiso lwedatha olungenamthungo kwaye ilungiselela inethiwekhi yakho ye-scalability yexesha elizayo. Nokuba ulawula uthungelwano lwamashishini amancinci okanye inkqubo yeshishini elikhulu, ukuqonda uLayiko 2 kunye nokutshintsha kweLayer 3 kunokukunceda wenze isigqibo esinolwazi.
Lungiselela ukukhula kunye nonxibelelwano: khetha ngobulumko!
