Yintoni i-2 vs. Ungqinisiso lwe-3?

Kwinethiwekhi, ukuqonda umahluko phakathi kwe-2 kunye ne-swing 3 yokutshintsha kubalulekile ekuyilweni kweziseko zophuhliso ezifanelekileyo. Zombini iindidi zezitshisi zinemisebenzi ephambili, kodwa zisetyenziswa kwiimeko ezahlukeneyo ngokuxhomekeka kwiimfuno zenethiwekhi. Masiphonononge ukungafani kwabo kunye nokusetyenziswa kwabo.

Yintoni i-STEDE 2 yokutshintsha?
Ukutshintsha kwe-2 Ukutshintsha kweSwikisi kusebenza kwi-Comple yekhonkco yemodeli ye-OSI. Ijolise ekudluliseleni idatha kwinethiwekhi yendawo enye yengingqi (LAN) ngokusebenzisa iidilesi ze-MC ukukhangela izixhobo.

Iimpawu eziphambili zobuqhetseba 2 Ukutshintsha:

Sebenzisa idilesi ye-MAC ukuthumela idatha kwisixhobo esichanekileyo ngaphakathi kwe-LAN.
Zonke izixhobo zihlala zivunyelwa ukuba zinxibelelane ngokukhululekileyo, ezisebenza kakuhle kwiinethiwekhi ezincinci kodwa zinokubangela ukuxinana kwiiseti ezinkulu.
Inkxaso yenethiwekhi yendawo yendawo yengingqi (i-vhls) yecandelo lenethiwekhi, ukuphucula intsebenzo kunye nokhuseleko.
I-Swingser 2 Switches ilungele uthungelwano oluncinci olungafuneki ukuba kungasebenzi kakuhle.

Yintoni i-3 itshintshela?
Ukuguqula ukutshintshela 3 Ukutshintsha kudibanisa ukudlulisela idatha kwi-thember 2 ukutshintshela ngokungena komsebenzi we-OSI yemodeli ye-OSI. Isebenzisa iidilesi ze-IP kwiDatha yeNdlela phakathi konxibelelwano okanye iimpuku ezahlukeneyo.

Iimpawu eziphambili zoMali 3 Ukutshintsha:

Unxibelelwano phakathi kweenethiwekhi ezimeleyo luphunyezwa ngokuhlalutya iidilesi ze-IP.
Ukuphuculwa kwentsebenzo kwizidimali ezinkulu ngokukhupha inethiwekhi yakho ukunciphisa ukudluliselwa kwedatha engafunekiyo.
Iindlela zedatha zinokwenziwa ngokulandelelana usebenzisa iiprotocol ze-roting ezifana ne-ospf, irip, okanye i-enigrp.
Ungqinisiso 3 Switches zihlala zisetyenziswa kwiindawo zeshishini apho ii-vhly ezininzi okanye iimpuku ezininzi kufuneka zinxibelelane.

Ungqimba 2 vs. Ungqimba 3: Umahluko ophambili
Ungqinisiso lwe-2 Switches lusebenza kwikhonkco lekhonkco ledatha kwaye ikakhulu zisetyenziselwa ukuthumela idatha kwinethiwekhi enye esekwe kwidilesi ye-MAC. Zilungele uthungelwano oluncinci lwasekhaya. Ungqimba 3 Switches, kwelinye icala, sebenza kwi-Newned Faceer kwaye usebenzise iidilesi ze-IP kwiDatha yeNdlela phakathi kweenethiwekhi ezahlukeneyo. Oku kubangela ukuba iindawo ezintle, ezininzi ezinzima zenethiwekhi ezifuna ukunxulumana phakathi kweendlela okanye ii-vhl.

Yeyiphi ekufuneka uyikhetha?
Ukuba inethiwekhi yakho ilula kwaye ikwindawo yokuhlala, i-Spaning Switch 2 ibonelela ngokusebenza kakuhle nokuchasana ngokuthe ngqo. Kwimimandla enkulu okanye indawo efuna ukuba nenxaxheba kwi-vsns, ungqimba utshintsho olufanelekileyo kukhetho olufanelekileyo ngakumbi.

Ukukhetha i-swindows efanelekileyo iqinisekisa ukudluliselwa kwedatha engenamthungo kwaye ilungiselela inethiwekhi yakho ye-scaldy yexesha elizayo. Nokuba uyayilawula inethiwekhi encinci yeshishini okanye inkqubo yeshishini elikhulu, ukuqonda ungqimba 2 kunye nobeko-ntetho 3 ukutshintsha kunokukunceda wenze isigqibo esiziyo.
