Lub network kis tau tus mob feem ntau muab faib ua peb txheej: txheej txheej, txheej txheej, txheej txheej.
Core txheej: Lub luag haujlwm ntawm cov txheej txheem tseem ceeb yog kom paub txog kev sib kis tau zoo ntawm cov pob txha caj qaum, thiab ua kom pom tseeb ntawmrov qab txheejKev tsim cov dej num feem ntau yog redundancy, kev cia siab, thiab kev sib kis ceev. Cov txheej txheem tseem ceeb yeej ib txwm suav tias yog qhov kawg tau txais thiab sib sau ua ke ntawm txhua qhov kev khiav tsheb, yog li qhov yuav tsum tau ua rau kev tsim cov txheej txheem tseem ceeb thiab cov khoom siv network yog nruj heev.
Convergence txheej: Lub convergence txheej yog "intermediary" ntawm lub network nkag txheej thiab cov txheej txheem tseem ceeb. Nws yog ua kom muaj kev sib koom ua ke ua ntej cov chaw ua haujlwm nkag mus rau cov txheej txheem tseem ceeb kom txo cov khoom thauj khoom ntawm cov khoom siv tub ntxhais. Cov txheej txheem sib sau ua ke muaj ntau yam haujlwm xws li kev siv txoj cai, kev ruaj ntseg, kev nkag mus rau pawg neeg ua haujlwm, routing ntawm virtual local network networks (VLANs), qhov chaw nyob lossis qhov chaw nyob lim, thiab lwm yam.
Cov txheej txheem nkag mus feem ntau yog hais txog ib feem ntawm lub network uas txuas ncaj qha lossis nkag los ntawm cov neeg siv. Cov txheej txheem nkag tau siv cov fiber ntau optical, twisted khub, coaxial cable, wireless nkag tshuab thiab lwm yam kev sib kis xov xwm kom paub txog kev sib txuas nrog cov neeg siv thiab faib cov kev pabcuam thiab bandwidth. Lub hom phiaj ntawm cov txheej txheem nkag mus yog tso cai rau cov neeg siv kawg txuas rau lub network, yog li nkag mus rau txheej txheej txheej txheem muaj tus nqi qis thiab qhov chaw nres nkoj siab.
HTF covHT6000 DWDM/OTNplatform yog tsuas yog siv nyob rau hauv lub aggregation txheej thiab cov tub ntxhais txheej los pab koj npaj cov kev pab cuam kis tau tus mob ntawm ntau lub ntsiab lus.
