Cov txheej txheem txheej txheem feem ntau yog siv rau kev xaiv txoj kev thiab kev xa mus nrawm, muab cov qauv kev sib txuas lus zoo thiab txhim khu kev qha, yog li cov tub ntxhais txheej txheej hloov daim ntawv thov muaj kev ntseeg siab dua thiab dhau los.Lub aggregation txheej hloov yog lub convergence point ntawm ntau nkag mus txheej keyboards.Nws ua haujlwm raws li kev sib koom ua ke ntawm A-Nodes, xa mus thiab xaiv txoj kev.Nws yuav tsum muaj peev xwm tswj tau tag nrho cov tsheb khiav los ntawm kev nkag mus rau txheej txheej thiab muab ib qho uplink rau cov txheej txheem tseem ceeb.Kev ua haujlwm ntawm cov txheej txheem nkag mus yog txuas tus neeg siv kawg rau lub network, yog li cov txheej txheem nkag mus tau muaj cov yam ntxwv ntawm tus nqi qis thiab qhov chaw nres nkoj siab.
Kev ua tau zoo sib txawv
Cov txheej txheem tseem ceeb yog txheej txheej 3 hloov nrog kev xa mus nrawm, muaj peev xwm loj interface bandwidth (xws li 10-gigabit interface), thiab muaj peev xwm ua haujlwm rov qab loj.Yog li ntawd, nws qhov kev ua tau zoo yog siab dua li ntawm cov txheej txheem sib sau ua ke thiab nkag mus rau txheej txheej hloov.Aggregation keyboards kuj muaj qee qhov kev ua haujlwm thiab tuaj yeem yog Txheej 2 lossis Txheej 3 hloov.Cov keyboards nkag mus yog Layer 2 keyboards.Yog li ntawd, aggregation keyboards muaj kev ua tau zoo dua, tsawg dua cov chaw nres nkoj, thiab cov nqi siab dua li cov keyboards nkag.Hauv luv luv, qhov kev sib piv kev ua tau zoo ntawm peb lub keyboards no yog: core txheej hloov> Aggregation txheej hloov> Access txheej hloov.
Siv qhov sib txawv scenario
Tsis muaj qhov yuav tsum tau ua kom ruaj khov rau cov tub ntxhais txheej hloov pauv, txheej txheej sib sau ua ke thiab nkag mus rau txheej txheej, uas txheej txheej lawv nyob hauv feem ntau yog nyob ntawm qhov loj ntawm lub network ib puag ncig thiab lub peev xwm xa tawm ntawm lub cuab yeej, tsis yog txhua lub network yuav tsum muaj peb cov qauv, qee lub tuam txhab tsuas yog nkag mus rau txheej txheej hloov thiab cov txheej txheem tseem ceeb hloov, ib qho ntawm lub hom phiaj ntawm txoj hauv kev no yog txhawm rau txuag nqi.
Cov kev ua haujlwm sib txawv ntawm cov txheej txheem nkag, txheej txheej txheej thiab cov txheej txheem tseem ceeb yog cov ntsiab lus tseem ceeb ntawm cov kev paub saum toj no.Raws li cov keyboards tau hais los saum toj no, lawv yog cov khoom siv sib txuas lus nrov hauv Shenzhen HDV Phoeletron Technology LTD., xws li: Ethernet hloov, Fiber hloov, Ethernet Fiber hloov, thiab lwm yam, cov keyboards saum toj no tuaj yeem siv ntau qhov chaw, muab kev xaiv ntau dua rau cov neeg siv nrog cov kev xav tau sib txawv, txais tos kom nkag siab, peb yuav muab cov kev pabcuam zoo tshaj plaws.
