Ua ntej, cia peb tsom mus rau:
Core keyboards tsis yog hom hloov,
Nws yog qhov hloov pauv tso rau ntawm cov txheej txheem tseem ceeb (network backbone).
1. Dab tsi yog qhov hloov pauv tseem ceeb
Feem ntau, cov tuam txhab lag luam loj thiab cov khw hauv internet yuav tsum tau yuav cov hloov pauv tseem ceeb kom ua tiav lub peev xwm nthuav dav hauv network thiab tiv thaiv kev nqis peev uas twb muaj lawm. Tsuas yog thaum tus naj npawb ntawm cov khoos phis tawj nce mus txog qee qib tuaj yeem siv cov hloov pauv tseem ceeb, thaum lub hauv paus tsis xav tau cov tub ntxhais keyboards qis dua 50, thiab routing txaus. Lub npe hu ua core hloov yog hais txog 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. Cov keyboards tseem ceeb feem ntau xa mus rau Txheej 2 lossis Txheej 3 cov keyboards uas muaj ob qho tib si kev tswj hwm lub network thiab muaj zog dhau. Hauv ib cheeb tsam network nrog ntau dua 100 lub khoos phis tawj, qhov hloov pauv tseem ceeb yog qhov tseem ceeb rau kev ua haujlwm ruaj khov thiab ceev ceev.
2. Qhov sib txawv ntawm cov keyboards tseem ceeb thiab tsis tu ncua
keyboards: Tus naj npawb ntawm cov chaw nres nkoj hauv cov keyboards tsis tu ncua feem ntau yog 24-48, thiab feem ntau ntawm cov chaw nres nkoj network yog gigabit Ethernet lossis gigabit Ethernet ports. Lub luag haujlwm tseem ceeb yog nkag mus rau cov neeg siv cov ntaub ntawv lossis sau cov ntaub ntawv hloov pauv los ntawm qee cov txheej txheem nkag. Hom kev hloov no tuaj yeem teeb tsa nrog Vlan yooj yim routing raws tu qauv thiab qee qhov yooj yim SNMP ua haujlwm ntawm feem ntau, thiab cov backplane bandwidth kuj me me. Muaj ntau tus tub ntxhais hloov chaw nres nkoj, uas feem ntau yog modular thiab tuaj yeem ua khub dawb nrog optical ports thiab gigabit Ethernet ports. Feem ntau, cov keyboards tseem ceeb yog peb-txheej hloov pauv uas tuaj yeem teeb tsa ntau yam kev sib txuas lus zoo xws li kev sib txuas lus / ACL / QoS / load ntsuas. Lub ntsiab lus tseem ceeb tshaj plaws yog qhov backplane bandwidth ntawm cov tub ntxhais hloov pauv ntau dua li cov keyboards ib txwm muaj, thiab lawv feem ntau muaj cov cav sib cais thiab yog thawj thiab thaub qab. Qhov sib txawv ntawm cov neeg siv txuas lossis nkag mus rau lub network: Ib feem ntawm lub network uas ncaj qha ntsib cov neeg siv txuas lossis nkag mus rau lub network feem ntau hu ua txheej txheej nkag, thiab ib feem ntawm txheej txheej nkag thiab txheej txheej tseem ceeb raug xa mus rau kev faib khoom. txheej los yog txheej txheej. Lub hom phiaj ntawm txheej txheej nkag yog tso cai rau cov neeg siv kawg txuas 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. Ib txheej txheej hloov pauv yog qhov sib txuam rau ntau qhov kev nkag mus rau txheej txheej, uas yuav tsum muaj peev xwm tswj tau tag nrho cov tsheb khiav los ntawm kev nkag mus rau txheej txheej thiab muab uplink rau txheej txheej. Yog li ntawd, cov txheej txheem sib sau ua ke muaj kev ua tau zoo dua, kev cuam tshuam tsawg dua, thiab kev hloov pauv ntau dua. Lub pob txha caj qaum ntawm lub network yog hu ua cov txheej txheem tseem ceeb, uas nws lub hom phiaj tseem ceeb yog los muab cov qauv kev sib txuas lus zoo thiab txhim khu kev qha los ntawm kev sib txuas lus ceev ceev. Yog li ntawd, daim ntawv thov txheej txheej tseem ceeb muaj kev ntseeg siab dua, kev ua tau zoo, thiab dhau mus.
Muab piv rau cov hloov pauv hloov pauv zoo tib yam, lawv yuav tsum muaj cov yam ntxwv xws li cache loj, muaj peev xwm siab, virtualization, scalability, thiab module redundancy technology. Tam sim no, kev lag luam hloov pauv tau sib xyaw, thiab cov khoom lag luam zoo tsis sib xws. Cov neeg siv tuaj yeem them sai sai rau CF FIBERLINK hauv kev xaiv cov khoom, thiab muaj ib qho kev hloov pauv uas haum rau koj!
