Cov tub ntxhais tsis yog tus qauv ntawm kev hloov pauv, tab sis qhov hloov pauv tau muab tso rau hauv qhov chaw tseem ceeb ntawm lub cuab yeej. Feem ntau nyob rau hauv loj-scale enterprise network installation thiab Internet cafe systems, core keyboards yog siv los txuas cov khoom siv los ntawm Akihabara Qeb 6 network cable kom ua tiav cov peev txheej muaj peev xwm nthuav dav. Qhov sib txawv ntawm lub network core keyboards thiab cov keyboards zoo tib yam yog tshwm sim hauv kev siv. Piv nrog rau cov keyboards zoo tib yam, cov keyboards tseem ceeb yuav tsum muaj cov yam ntxwv xws li cov cache loj, muaj peev xwm siab, virtualization, scalability, thiab module redundancy technology.
Qhov sib txawv ntawm network core keyboards thiab cov keyboards zoo tib yam
Txawm li cas los xij, muaj qee qhov kev xav tau rau kev siv cov tub ntxhais hloov pauv hauv lub network. Feem ntau, cov hloov pauv tseem ceeb tsuas yog siv thaum muaj pes tsawg lub khoos phis tawj mus txog qee tus lej. Cov keyboards tseem ceeb tsis tas yuav tsum muaj rau 50 lub khoos phis tawj, thiab lub router txaus. Lub core hloov yog rau lub network architecture. Yog tias nws yog ib qho chaw me me hauv cheeb tsam nrog ntau lub khoos phis tawj, 8-chaw nres nkoj me me tuaj yeem hu ua qhov hloov pauv tseem ceeb.
Qhov sib txawv ntawm cov keyboards tseem ceeb thiab cov keyboards zoo tib yam
1. Qhov sib txawv ntawm cov chaw nres nkoj
Tus naj npawb ntawm cov chaw hloov pauv ib txwm yog feem ntau 24-48. Feem ntau ntawm cov chaw nres nkoj network yog Gigabit Ethernet lossis Fast Ethernet ports. Lub luag haujlwm tseem ceeb yog nkag mus rau cov neeg siv cov ntaub ntawv lossis sib sau ua ke qee cov txheej txheem nkag mus hloov cov ntaub ntawv. Hom kev hloov no tuaj yeem siv tau ntawm feem ntau Configure Vlan yooj yim routing raws tu qauv thiab qee qhov yooj yim SNMP zog, backplane bandwidth kuj me me.
2. Qhov txawv ntawm tus neeg siv' kev sib txuas lossis kev nkag mus rau lub network
Feem ntau yog ib feem ntawm lub network uas ncaj qha ntsib cov neeg siv los txuas lossis nkag mus rau hauv lub network yog hu ua txheej txheej nkag, thiab ib feem ntawm txheej txheej nkag thiab txheej txheej tseem ceeb yog hu ua txheej txheej txheej lossis txheej txheej txheej. Lub hom phiaj ntawm txheej txheej nkag yog tso cai rau cov neeg siv kawg txuas rau lub network. Yog li ntawd, cov txheej txheem nkag mus tau muaj cov yam ntxwv ntawm tus nqi qis thiab qhov chaw nres nkoj siab.
Lub aggregation txheej hloov yog lub convergence point ntawm ntau nkag mus txheej keyboards. Nws yuav tsum muaj peev xwm tswj tau tag nrho cov tsheb khiav los ntawm cov khoom siv txheej txheej nkag thiab muab ib qho uplink rau cov tub ntxhais txheej. Yog li ntawd, cov txheej txheem sib sau ua ke muaj kev ua tau zoo dua thiab tsawg dua Interface thiab ntau dua kev sib pauv.
Lub nraub qaum ntawm lub network yog hu ua cov txheej txheem tseem ceeb. Lub hom phiaj tseem ceeb ntawm cov txheej txheem tseem ceeb yog los muab kev txhim kho zoo thiab txhim khu kev qha cov pob txha kis tau tus mob los ntawm kev sib txuas lus ceev ceev. Yog li ntawd, cov txheej txheem tseem ceeb hloov daim ntawv thov muaj kev ntseeg siab dua, kev ua tau zoo thiab dhau mus.
