Txawm hais tias ob qho tib si siv rau kev hloov pauv network, muaj qhov sib txawv hauv kev ua haujlwm.

Qhov txawv 1:Lub load thiab subnetting yog txawv.Tsuas muaj ib txoj hauv kev ntawm Ethernet keyboards, yog li cov ntaub ntawv tseem ceeb ntawm ib qho kev sib txuas lus thiab tsis tuaj yeem muab faib ua kom sib npaug ntawm cov khoom thauj.Lub router txoj kev routing raws tu qauv algorithm tuaj yeem zam qhov no.OSPF routing protocol algorithm tuaj yeem tsis tsuas yog tsim ntau txoj hauv kev, tab sis kuj xaiv cov kev pom zoo sib txawv rau cov ntawv thov sib txawv.Nws tuaj yeem pom tias lub nra ntawm lub router yog qhov loj dua li ntawm Ethernet hloov.Ethernet keyboards tsuas paub txog MAC chaw nyob.MAC chaw nyob yog lub cev chaw nyob thiab muaj cov qauv chaw nyob tiaj tus, yog li subnetting tsis tuaj yeem ua raws li MAC chaw nyob.Lub router txheeb xyuas qhov chaw nyob IP, uas tau muab los ntawm tus thawj tswj hwm network.Nws yog qhov chaw nyob qhov tseeb thiab qhov chaw nyob IP muaj cov qauv hierarchical.Nws tau muab faib ua tus lej network thiab tus lej tswv, uas tuaj yeem siv tau yooj yim los faib cov subnets.Lub luag haujlwm tseem ceeb ntawm lub router yog siv txuas mus rau cov network sib txawv

Qhov txawv 2:Kev tshaj tawm thiab kev tshaj tawm xov xwm yog txawv.Ethernet hloov tsuas tuaj yeem txo qhov kev sib tsoo, tab sis tsis yog qhov tshaj tawm.Tag nrho lub network hloov pauv yog qhov loj tshaj tawm tshaj tawm, thiab cov pob ntawv tshaj tawm tau muab faib rau tag nrho lub network hloov pauv.Lub router tuaj yeem cais tawm cov npe tshaj tawm, thiab cov pob ntawv tshaj tawm tsis tuaj yeem txuas ntxiv tshaj tawm hauv lub router.Nws tuaj yeem pom tau tias qhov ntau ntawm kev tswj hwm kev tshaj tawm ntawm Ethernet keyboards yog ntau dua li ntawm routers, thiab qhov ntau ntawm kev tshaj tawm xov xwm ntawm routers tseem me me.Raws li cov khoom siv txuas txuas, Ethernet hloov tuaj yeem ua tiav qhov kev hloov pauv ntawm cov txheej txheem sib txuas thiab cov txheej txheem ntawm lub cev, tab sis cov txheej txheem hloov dua siab tshiab no nyuaj thiab tsis haum rau kev siv ASIC, uas yuav ua rau txo qis kev xa mus ceev ntawm kev hloov.
