Dab tsi yog txheej 2 vs. txheej 3 hloov?

Hauv kev sib tham, nkag siab qhov sib txawv ntawm txheej 2 thiab txheej 3 hloov yog qhov tseem ceeb rau kev tsim cov khoom siv hluav taws xob. Ob hom kev hloov tau muaj cov haujlwm tseem ceeb, tab sis lawv tau siv nyob rau hauv txawv cov xwm txheej nyob ntawm kev cai siv network. Cia peb tshawb txog lawv qhov sib txawv thiab kev siv.

Dab tsi yog txheej 2 hloov?
Txheej 2 hloov ua haujlwm ntawm cov ntaub ntawv txuas ntawm tus qauv OSI. Nws tsom rau cov ntaub ntawv xa tawm hauv ib cheeb tsam ib cheeb tsam network (LAN) los ntawm kev siv MAC chaw rau txheeb cov khoom siv.

Cov Nta Tseem Ntawm Txheej 2 Hloov Mus Los:

Siv lub Mac chaw nyob xa cov ntaub ntawv rau cov cuab yeej raug nyob hauv LAN.
Txhua cov khoom siv feem ntau tso cai rau sib txuas lus dawb, uas ua haujlwm zoo rau cov tes hauj lwm me tab sis tuaj yeem ua rau kev sib tw hauv cov teeb tsa loj.
Kev them nyiaj yug rau Virtual Chaw Hauv Cheeb Tsam Networks (VLANS) rau Network Segmentation, txhim kho kev ua tau zoo thiab kev nyab xeeb.
Txheej 2 lub zog yog qhov zoo rau cov tes hauj lwm me me uas tsis tas yuav muaj peev xwm ua tau zoo.

Dab tsi yog txheej 3 hloov?
Txheej 3 hloov mus ua ke cov ntaub ntawv xa cov ntaub ntawv ntawm ib txheej 2 hloov nrog cov kev sib tw ntawm lub peev xwm ntawm lub network txheej ntawm tus qauv OSI. Nws siv IP chaw nyob rau cov ntaub ntawv ntawm cov haujlwm sib txawv lossis cov subnets.

Cov yam ntxwv tseem ceeb ntawm txheej 3 hloov:

Kev sib txuas lus ntawm kev sib txuas lus ywj siab yog ua tiav los ntawm kev txheeb xyuas tus IP chaw nyob.
Txhim kho kev ua haujlwm hauv cov chaw ib puag ncig loj los ntawm segmenting koj lub network kom txo cov ntaub ntawv hloov tsis tsim nyog tsis tsim nyog.
Cov ntaub ntawv txoj kev tuaj yeem ua tau zoo siv cov kev cai xws li ESPF, RIP, lossis EIGRP.
Txheej 3 lub tshuab hluav taws xob feem ntau siv hauv kev ua lag luam ib puag ncig uas muaj ntau vlans lossis subnets yuav tsum sib cuam tshuam.

Txheej 2 vs. Txheej 3: sib txawv
Txheej 2 lub tshuab hloov chaw ua haujlwm ntawm cov ntaub ntawv txuas cov ntaub ntawv thiab feem ntau siv rau cov ntaub ntawv hauv ntej hauv ib qho network raws li MAC chaw nyob. Lawv yog qhov zoo tagnrho rau cov network me me. Txheej 3 Windages, ntawm qhov tod tes, ua haujlwm ntawm lub network txheej thiab siv IP chaw nyob rau cov ntaub ntawv sib txawv ntawm cov tes hauj lwm sib txawv. Qhov no ua rau lawv xaiv zoo rau qhov loj dua, ntau dua cov network ib puag ncig uas yuav tsum muaj cov sib cuam tshuam ntawm cov subnets lossis Vlans.

Koj yuav xaiv qhov twg?
Yog tias koj lub network yog qhov yooj yim thiab ib cheeb tsam, ib txheej 2 hloov muab cov nqi-ua tau zoo thiab ncaj qha ua haujlwm. Rau cov tes hauj lwm loj lossis ib puag ncig uas yuav tsum muaj kev sib cuam tshuam thoob plaws Vlans, ib txheej 3 hloov yog qhov kev xaiv tsim nyog dua.

Xaiv txoj cai hloov ua kom cov ntaub ntawv hloov chaw thiab npaj koj lub network rau yav tom ntej hauv lub ntsuas cua. Seb koj tswj hwm ib qho kev lag luam me me lossis kev nkag siab txheej txheem, nkag siab txheej 2 thiab txheej 3 hloov tuaj yeem pab koj kom txiav txim siab paub.

Txhim kho rau kev loj hlob thiab kev sib txuas: Xaiv kom zoo!
