Kunethiwekhi, ukuqonda umehluko phakathi kwesendlalelo 2 nokushintsha kwesendlalelo 3 kubalulekile ekwakheni ingqalasizinda efanelekile. Zombili lezi zinhlobo zokushintshwa zinemisebenzi ebalulekile, kepha zisetshenziswa ezimweni ezihlukile ngokuya ngezidingo zenethiwekhi. Ake sihlole umehluko kanye nezicelo zabo.
Yini ungqimba 2 ukushintshana?
I-Layer 2 Ukushintshwa kusebenza engxenyeni yesixhumanisi sedatha yemodeli ye-Osi. Igxile ekudluliseni phambili idatha ngaphakathi kwenethiwekhi yendawo eyodwa (i-LAN) ngokusebenzisa amakheli e-MAC ukukhomba amadivayisi.
Izici ezibalulekile zokushintshwa kwesendlalelo 2:
Sebenzisa ikheli le-MAC ukuthumela idatha kudivayisi efanele ngaphakathi kwe-LAN.
Wonke amadivayisi avame ukuvunyelwa ukuxhumana ngokukhululeka, okusebenza kahle kumanethiwekhi amancane kepha kungadala ukuxinana ngamasu amakhulu.
Ukusekelwa kwamanethiwekhi wendawo yendawo (ama-VLANS) engxenyeni yenethiwekhi, ukuthuthukisa ukusebenza nokuphepha.
I-Layer 2 switchs ilungele amanethiwekhi amancane angadingi amakhono athuthukile e-routing.
Yini ungqimba 3 ukushintshana?
Ukushintshwa kwesendlalelo 3 kuhlanganisa ukudluliswa kwedatha kokushintshwa kwesendlalelo 2 namandla okuhambisa ingqimba yenethiwekhi yemodeli ye-OSI. Isebenzisa amakheli we-IP kwimininingwane yomzila phakathi kwamanethiwekhi ahlukene noma ama-subnets.
Izici ezibalulekile zokushintshwa kwesendlalelo 3:
Ukuxhumana phakathi kwamanethiwekhi azimele kutholakala ngokuhlaziya amakheli we-IP.
Thuthukisa ukusebenza ezindaweni ezikhudlwana ngokuhlukanisa inethiwekhi yakho ukuze unciphise ukudluliselwa kwedatha okungadingekile.
Izindlela zedatha zingahle zilungiswe ngokuqinile kusetshenziswa ama-protocol e-aspf, i-RIP, noma i-EIGRY.
Ukushintshwa kwesendlalelo 3 kuvame ukusetshenziswa ezindaweni zebhizinisi lapho amaVlans noma ama-VLAN amaningi kufanele axhumane khona.
Ungqimba 2 vs. ungqimba 3: umehluko obalulekile
I-Layer 2 switch isebenza ku-Idatha yokuxhumanisa yedatha futhi ngokuyinhloko isetshenziselwa ukudlulisa idatha ngaphakathi kwenethiwekhi eyodwa ngokususelwa ekhelini le-MAC. Zilungele amanethiwekhi amancane endawo. I-Layer 3 switchs, ngakolunye uhlangothi, sebenza ungqimba lwenethiwekhi futhi usebenzise amakheli we-IP kwimininingwane yomzila phakathi kwamanethiwekhi ahlukile. Lokhu kubenza babe ukukhetha okuhle kakhulu kwabakhulu, izindawo eziyinkimbinkimbi zenethiwekhi ezidinga ukuxhumana phakathi kwama-subnets noma amaVlan.
Yikuphi okufanele ukhethe?
Uma inethiwekhi yakho ilula futhi yendawo, ungqimba 2 switchch anikeza ukusebenza okusebenzayo nokuqondile. Kumanethiwekhi amakhulu noma izindawo ezidinga ukusebenzisana kuwo wonke amaVlans, i-arler 3 switch iyisinqumo esifanele.
Ukukhetha ukushintsha okulungile kuqinisekisa ukudluliswa kwedatha okungenamthungo futhi kulungiselela inethiwekhi yakho ukuze uthole ukuqina okuzayo. Ukuthi ngabe uphatha inethiwekhi encane yebhizinisi noma uhlelo lwebhizinisi elikhulu, ukuqonda okuqondayo 2 nokushintshwa kwesendlalelo 3 kungakusiza wenze isinqumo esinolwazi.
Lungiselela ukukhula nokuxhuma: Khetha ngobuhlakani!
