Cisco Systems tsim ntau yam khoom siv hauv computer xws li network routers rau tsev thiab kev lag luam. Cisco routers tseem nrov thiab tau txais lub koob npe nrov ntau xyoo rau kev ua tau zoo thiab kev ua haujlwm siab.
Cisco Routers rau Tsev
Los ntawm 2003 txog 2013, Cisco Systems muaj lub lag luam Linksys thiab lub npe hom. Linksys wired thiab wireless router qauv tau dhau los ua qhov kev xaiv nrov heev rau kev sib tham hauv tsev thaum lub sijhawm no. Xyoo 2010, Cisco kuj tau tsim nws txoj kab Valet ntawm lub tsev network routers.
Vim Cisco txiav tawm Valet thiab Linksys muag rau Belkin, Cisco tsis ncaj qha ua lag luam ib qho ntawm nws cov routers tshiab rau cov tswv tsev. Qee yam ntawm lawv cov khoom qub tseem muaj nyob hauv kev muag khoom thib ob lossis muag khoom muag.

Cov chaw muab kev pabcuam feem ntau siv Cisco lub routers los tsim cov kev sib txuas mus deb ntawm Internet thaum ntxov thaum xyoo 1980 thiab 1990s. Ntau lub tuam txhab kuj tau txais Cisco routers los txhawb lawv cov tes hauj lwm intranet.
Cisco CRS - Cov Khoom Siv Routing System
Core routers zoo li CRS tsev neeg ua haujlwm ua lub plawv ntawm lub lag luam loj hauv kev sib txuas uas lwm cov routers thiab keyboards tuaj yeem txuas nrog. Thawj zaug tau tshaj tawm hauv xyoo 2004, CRS-1 muab 40 Gbps kev sib txuas nrog kev sib txuas network bandwidth scalable mus txog 92 terabits ib ob. Tus tshiab CRS-X txhawb 400 Gbps kev sib txuas.

Ntug routers zoo li Cisco ASR series ntawm cov khoom lag luam ncaj qha cuam tshuam kev lag luam network rau Is Taws Nem lossis lwm qhov chaw dav dav (WANs). ASR 9000 Series routers yog rau cov neeg nqa khoom sib txuas lus thiab cov chaw muab kev pabcuam, thaum cov lag luam tuaj yeem siv tus nqi pheej yig dua ASR 1000 Series.
Cisco ISR - Kev Pabcuam Routers
Cisco muaj ntau theem ntawm ISRs rau ntau qhov kev lag luam. Cov qauv kab yog:
- 800: me me routers nrog wireless, suab, thiab muaj peev xwm ruaj ntseg
- 900: nkag qib khoom siv rau cov lag luam me
- 1000: routing thiab wireless rau cov lag luam me thiab nruab nrab
- 1800: mus txog yim 10/100 Mbps ports
- 1900: txhawb txog plaub lub routers siv 25 Mbps ntawm bandwidth
- 4000: siab-bandwidth - mus txog 7 Gbps
Lwm Hom Cisco Routers
Cisco tau tsim thiab ua lag luam ntau yam ntawm lwm cov khoom siv router ntau xyoo, suav nrog:
- Cisco 1000 thiab 2000 Series Txuas Daim phiaj: sab hauv tsev / sab nraum zoov routers, feem ntau yog siv rau cov chaw siv hluav taws xob thiab cov hluav taws xob hluav taws xob hluav taws xob.
- Cisco 500, 800, thiab 900 Series Industrial: txhawb kev sib koom ua ke ntawm wireless sensors thiab Internet ntawm Yam (IoT) cov khoom siv hauv thaj chaw sab nraum zoov thiab kev tsim kho.
- Cisco Mobile Wireless Routers: txhawb nqa cellular backhaul network ib puag ncig.
About Cisco IOS
IOS (Internetwork Operating System) yog cov software qis qis uas khiav ntawm Cisco routers (thiab qee lwm Cisco li). IOS txhawb nqa cov lus txib-kab neeg siv lub plhaub thiab cov laj thawj hauv qab rau kev tswj hwm lub router cov khoom siv (nrog rau kev nco thiab tswj fais fab, ntxiv rau kev tswj hwm Ethernet thiab lwm yam kev sib txuas ntawm lub cev). Nws kuj tseem ua rau muaj ntau tus qauv network routing protocols Cisco routers txhawb nqa zoo li BGP thiab EIGRP.
Cisco muaj ob qhov kev hloov pauv hu ua IOS XE thiab IOS XR uas txhua tus khiav ntawm qee cov chav kawm ntawm Cisco routers thiab muaj peev xwm ntxiv tshaj qhov tseem ceeb ntawm IOS.
