Cisco Systems ua kom muaj ntau yam khoom siv computer xws li network routers rau cov tsev thiab cov lag luam. Cisco routers tseem nrov thiab tau txais ib lub koob npe nrov ntau xyoo rau kev ua tau zoo thiab ua tau zoo.
Cisco Routers rau Tsev
Los ntawm 2003 mus rau 2013, Cisco Systems muaj cov Linksys lag luam thiab cov npe tshwj xeeb. Linksys wired thiab wireless router qauv los ua ib qho kev xaiv tsis tshua muaj neeg nyiam nyob rau hauv tsev thaum sib tham no. Nyob rau hauv 2010, Cisco kuj ua nws Valet kab ntawm tsev network routers.
Txij li thaum Cisco Valet raug txiav thiab Linksys muag muag rau Belkin, Cisco tsis ncaj nraim ua lag luam ib yam ntawm nws cov tshiab routers rau cov tswv tsev. Qee yam ntawm lawv cov khoom qub yuav tsum muaj nyob rau hauv los ntawm ob lub tsev auction lossis khoom muag tawm.
Cisco Routers thiab hauv Internet
Cov chaw muab kev pab cuam feem ntau siv Cisco cov kev khiav haujlwm los tsim cov kev sib txuas ntev ntawm Internet thaum lub sijhawm xyoo 1980 thiab 1990. Ntau cov tuam txhab tau kuj tau hloov Cisco routers los txhawb lawv lub network rau intranet .
Cisco CRS - Kev Ruaj Ntseg Ruaj
Core routers zoo li CRS tsev neeg ua haujlwm ua lub plawv ntawm lub tuam txhab lag luam loj loj uas ua rau lwm txoj kev khiav thiab cov keyboards tau txuas nrog. Ua ntej pib hauv xyoo 2004, CRS-1 muaj 40 Gbps cov kev sib txuas nrog kev sib sau ua ke ntawm cov khoom sib txuas ua ke mus txog 92 qhov kev ua tauj thib ob. Qhov tshiab CRS-3 txhawb kev sib txuas 140 Gbps thiab 3.5x ntau dua kev sib tw bandwidth.
Cisco ASR - Aggregation Service Routers
Edge routers xws li cov Cisco ASR series ntawm cov khoom ncaj qha mus nruab ib lub tuam txhab lag luam rau hauv Internet los yog lwm qhov chaw sib koom tes (WANs) . ASR 9000 Series routers yog tsim los siv kev sib txuas lus ntawm cov neeg nqa khoom thiab cov chaw muab kev pabcuam, thaum tseem pheej yig ASR 1000 Series routers kuj siv los ntawm cov lag luam.
Cisco ISR - Cov Kev Pabcuam Kev Sib Txuas Lus
1900, 2900 thiab 3900 series Cisco ISR routers. Cov pawg thib ob ntawm cov ceg no hloov cov neeg laus 1800/2800/3800 series cov neeg ua haujlwm.
Lwm hom Cisco Routers
Cisco tau tsim thiab ua lag luam ntau ntau ntawm lwm yam khoom siv router ntau lub xyoo xws li:
- Cisco 1000 thiab 2000 Series Sib Txuas Sib Thoob hauv cov chaw sab hauv / chaw sab nraud, feem ntau yog siv nrog cov zog zog thiab cov chaw siv hluav taws xob sib txuas.
- Cisco 500 thiab Cisco 900 Series Cov chaw khiav haujlwm, muaj kev koom ua ke ntawm wireless sensor thiab Internet ntawm Yam (IoT) cov cuab yeej siv nyob rau sab nraum zoov thiab kev tsim kev lag luam.
- Cisco Mobile Wireless Routers , uas txhawb nqa kev lag luam ntawm lub xov tooj ntawm tes.
Nqi ntawm Cisco Routers
Tshiab high-end Cisco ASR ntug routers nqa cov nqi muag khoom muaj nqis tshaj $ 10,000 USD thaum cov tub ntxhais kev ua zoo li CRS-3 ntau tshaj $ 100,000. Cov lag luam loj tshaj plaws kuj yuav tau txais kev pabcuam thiab kev cog lus txhawb kev sib cog lus raws li ib feem ntawm lawv cov khoom siv yuav kho, ntxiv cov nqi tag nrho. Conversely, low-end Cisco tus qauv yuav tau muas tsawg dua $ 500 USD hauv qee qhov.
Txog Cisco IOS
IOS (Internetwork Operating System) yog qhov software uas tsis tshua muaj suab npe uas sau rau Cisco routers (thiab lwm yam Cisco devices). IOS txhawb kev sib txuas lus ntawm cov neeg siv hauv kev sib tham thiab lwm cov logic rau tswj cov router kho vajtse (nrog rau kev nco thiab lub hwj chim tswj, ntxiv rau kev tswj lub Ethernet thiab lwm yam kev sib txuas ntawm lub cev). Nws kuj ua rau ntau tus qauv kev sib koom ua ke Cisco routers txhawb xws li BGP thiab EIGRP .
Cisco muaj ob lub variations hu ua IOS XE thiab IOS XR uas txhua tus khiav ntawm qee cov chav kawm ntawm Cisco routers thiab muaj cov kev pabcuam ntxiv dhau qhov core functions ntawm IOS.
Hais txog Cisco Catalyst Devices
Catalyst yog Cisco lub hom lag luam rau lawv tsev neeg ntawm cov koos pij hluav taws xob . Thaum lub cev tsis tshua zoo li cov neeg khiav dej num, keyboards tsis muaj peev xwm tswj cov khoom ntim thoob hauv cheeb tsam.
