Lub luag haujlwm tseem ceeb ntawm kev hloov pauv muaj xws li qhov chaw nyob ntawm lub cev, lub network topology, kev kuaj xyuas qhov yuam kev, thav duab ib ntus, thiab tswj kev ntws. Tam sim no, qhov hloov pauv kuj tseem muaj qee qhov haujlwm tshiab, xws li kev txhawb nqa rau VLAN (virtual local network network), kev txhawb nqa rau kev sib txuas sib txuas, thiab qee qhov tseem muaj lub luag haujlwm ntawm firewall.
Ntxiv nrog rau kev sib txuas tib hom network, qhov hloov pauv tuaj yeem ua lub luag haujlwm sib txuas ntawm ntau hom kev sib txuas (xws li Ethernet thiab Fast Ethernet). Ntau lub keyboards niaj hnub no tuaj yeem muab cov chaw nres nkoj sib txuas ceev uas txhawb nqa Fast Ethernet lossis FDDI, thiab lwm yam, rau kev sib txuas lwm cov keyboards hauv lub network lossis muab cov bandwidth ntxiv rau cov servers tseem ceeb uas siv ntau qhov bandwidth.
Feem ntau hais lus, txhua qhov chaw nres nkoj ntawm qhov hloov pauv yog siv los txuas cov ntu kev ywj pheej, tab sis qee zaum txhawm rau muab kev nkag mus tau nrawm dua, peb tuaj yeem txuas ncaj qha rau qee qhov tseem ceeb hauv lub computer mus rau qhov chaw nres nkoj ntawm qhov hloov. Nyob rau hauv txoj kev no, cov servers tseem ceeb thiab cov neeg siv tseem ceeb ntawm lub network muaj kev nkag tau nrawm dua thiab txhawb nqa cov ntaub ntawv ntau dua.
Kev kawm muaj nuj nqi: Ethernet hloov kawm paub MAC chaw nyob ntawm lub cuab yeej txuas nrog txhua qhov chaw nres nkoj, thiab qhia qhov chaw nyob nrog qhov chaw sib txuas thiab khaws cia rau hauv MAC chaw nyob hauv lub cache hloov.
Forwarding filtering: Thaum qhov chaw nyob qhov chaw nyob ntawm cov ntaub ntawv thav duab yog mapped nyob rau hauv lub MAC chaw nyob lub rooj, nws yog xa mus rau qhov chaw nres nkoj txuas nrog rau lo lus uas peb node es tsis txhob ntawm tag nrho cov ports (yog hais tias cov ntaub ntawv ncej yog ib tug tshaj tawm / multicast ncej, nws yog xa mus rau. tag nrho cov chaw nres nkoj).
Loop Elimination: Thaum qhov hloov pauv suav nrog lub voj tsis dhau, Ethernet hloov pauv tsis txhob voj voog los ntawm Spanning Tree Protocol thaum tso cai rau txoj hauv kev muaj nyob.
Kev Kawm: Ethernet hloov nkag siab txog MAC chaw nyob ntawm lub cuab yeej txuas nrog txhua qhov chaw nres nkoj, thiab kos npe qhov chaw nyob nrog qhov chaw sib txuas thiab khaws cia rau hauv MAC chaw nyob hauv lub cache hloov.
Kev xa tawm / lim: Thaum qhov chaw nyob ntawm qhov chaw nyob ntawm cov ntaub ntawv thav duab tau teeb tsa hauv MAC qhov chaw nyob, nws raug xa mus rau qhov chaw nres nkoj uas nyob ib sab ntawm qhov chaw nres nkoj es tsis txhob tag nrho cov chaw nres nkoj (yog tias cov ntaub ntawv thav duab yog kev tshaj tawm / multicast, nws raug xa mus. rau txhua qhov chaw nres nkoj).
