Txoj Kev Txhim Kho ntawm Routers

Tam sim no, txoj kev loj hlob ntawmwifi routeryog ceev heev.Kuv ntseeg tias nrog txoj kev loj hlob ntawm kev lag luam kev sib txuas lus, router technology kuj yuav zoo meej thiab ruaj khov, nqa lub network zoo rau cov neeg siv.

Nrog kev txhim kho txuas ntxiv ntawm wifi router, Kuv tau kawm txog kev txhim kho ntawm routers raws li ALL IP sib, thiab qhia rau koj ntawm no, vam tias yuav muaj txiaj ntsig rau koj.Cov kev pabcuam ntau yam ntawm IP tes hauj lwm muaj qhov zoo ntawm kev sib koom ua ke thiab kev sib txuas, uas tuaj yeem nthuav dav kev lag luam sai, ua kom yooj yim cov txheej txheem hauv network, txo kev tsim kho, kev ua haujlwm thiab kev saib xyuas, thiab kev lag luam kev lag luam cov nqi kev pabcuam, thiab kev tswj xyuas cov neeg siv khoom yooj yim.Yog li ntawd, ib qho kev sib koom ua ke IP tus neeg tuav lub network yuav tuaj yeem txhawb nqa kev lag luam kev lag luam ntau dua.

Txhawm rau hloov mus rau qhov kev hloov pauv no, ib txwm siv IP tus neeg nqa khoom sib txuas yuav tsum tau hloov pauv kom ua tiav lub hom phiaj ntawm kev pabcuam ntau tus tuav.Cov cuab yeej siv Router, uas yog cov cuab yeej tseem ceeb ntawm IP tes hauj lwm, muaj qhov cuam tshuam tseem ceeb rau kev ruaj ntseg hauv lub tebchaws, kev tsim kho kev lag luam, thiab kev tsim cov ntaub ntawv sib raug zoo vim nws txoj kev ruaj ntseg, muaj, thiab kev ntseeg tau.

Router Devices nyob rau hauv Kev Hloov Hloov ntawm IP Networks

Vim muaj kev siv ntau ntawm IP tes hauj lwm nyob rau hauv xyoo tas los no thiab qhov kev thov tshiab rau ntau qhov kev pab cuam hauv IP tes hauj lwm, router cov cuab yeej muaj cov kev txhim kho tshiab hauv qab no.

Interface zoo li high-speed

Thaum pib ntawm kev tsim qauv, lub luag haujlwm tseem ceeb ntawm cov cuab yeej router yog hloov mus rau cov kev sib txuas ceev hauv cheeb tsam hauv cheeb tsam thiab qis-ceev dav hauv cheeb tsam network.Nrog kev txhim kho thev naus laus zis, cov cuab yeej router tau dhau los ua cov cuab yeej tseem ceeb ntawm IP tes hauj lwm.Maj mam muab qhov tseem ceeb rau cov teeb meem kev nyab xeeb.Kev ruaj ntseg hauv lub network feem ntau suav nrog kev ruaj ntseg ntawm lub network nws tus kheej, kev ruaj ntseg ntawm kev pabcuam network, kev ruaj ntseg ntawm cov ntaub ntawv siv network, thiab kev tswj cov ntaub ntawv tsis zoo.Raws li cov khoom siv hauv network tseem ceeb, cov cuab yeej router muaj kev sib raug zoo nrog kev ruaj ntseg network, thiab tseem tuaj yeem ua lub luag haujlwm hauv kev ua kom cov ntaub ntawv kev ruaj ntseg ntawm cov neeg siv network.

Thaum pib, cov cuab yeej siv router kev nyab xeeb feem ntau cuam tshuam nrog kev ntseeg siab ntawm cov khoom siv hauv network nws tus kheej, thaub qab ntawm cov khoom tseem ceeb, cov yam ntxwv hluav taws xob ntawm cov khoom siv network, thiab cov ntsuas kev ua haujlwm ntawm cov khoom siv network.Nrog rau kev loj hlob ntawm cov nplai ntawm Is Taws Nem thiab kev nce qib ntawm thev naus laus zis, kev lees paub kev ruaj ntseg network muaj cov cai tshiab rau cov khoom siv router.Nyob rau theem kev tswj hwm, kev ruaj ntseg yuav tsum tau ua kom muaj kev ruaj ntseg ntawm kev tswj cov ntaub ntawv nkag mus, tswj cov ntaub ntawv pov thawj, tswj cov ntaub ntawv muaj, tswj cov ntaub ntawv tsis rov qab, tswj cov ntaub ntawv kev sib txuas lus ruaj ntseg, thiab tswj cov ntaub ntawv ncaj ncees thiab kev ceev ntiag tug.Nyob rau theem kev tswj hwm, kev nyab xeeb yuav tsum tau ua kom muaj kev nyab xeeb hauv txhua yam ntawm kev tswj hwm cov cai saum toj no.Nyob rau hauv cov ntaub ntawv dav hlau, kev ruaj ntseg yuav tsum tau ua kom ntseeg tau tias muaj peev xwm muaj peev xwm los xyuas kom meej tias cov neeg siv tau tso cai tsis muaj kev cuam tshuam hauv lub network vim muaj kev cuam tshuam hauv network.Router pab kiag li lawm yuav tsum tau nce siab ceev interfaces los tsim broadband qaum tes hauj lwm.Tam sim no, kev lag luam routers tau mus txog 40Gbit / s, thiab cov chaw soj nstuam tau tshaj 100Gbit / s, nce mus txog qhov txwv ntawm kev teeb tsa hluav taws xob.

Lub peev xwm hloov tau zoo li loj heev thiab pawg

Nrog rau kev loj hlob sai ntawm cov ntaub ntawv thev naus laus zis, cov kev pabcuam nqa los ntawm kev sib txuas lus tau dhau los ua neeg nplua nuj, tshwj xeeb tshaj yog kev loj hlob sai ntawm IPTV, lub suab xov tooj ntawm tes, P2P thiab lwm yam kev pabcuam, thiab qhov kev thov rau bandwidth hauv cov pob txha caj qaum yog nce.Hauv ob peb xyoos dhau los, qhov kev loj hlob txhua xyoo ntawm pob tw tsheb thiab bandwidth xav tau nyob hauv Suav teb tau tshaj 200%, thiab nws xav tias qhov kev loj hlob txhua xyoo nyob rau ob peb xyoos tom ntej no tseem yuav siab txog li 100%.Yog li ntawd, IP caj qaum tes hauj lwm tau ntsib lub siab ntawm kev hloov kho ntau zaus thiab kev nthuav dav, thiab kev scalability tau dhau los ua ib qho tseem ceeb hauv kev tsim kho kom ruaj khov.

Qhov teeb meem tseem ceeb tshaj plaws hauv kev nthuav dav ntawm IP qaum tes hauj lwm yog kev nthuav dav ntawm lub peev xwm ntawm cov tub ntxhais router cov cuab yeej.Vim qhov kev loj hlob sai ntawm cov kev pabcuam hauv lub cev, IP network infrastructure yuav tsum tau hloov kho txhua ob xyoos lossis ntau dua.Cov neeg ua haujlwm tsis tuaj yeem zam dhau qhov kev hloov kho tshiab hauv network tsis tu ncua, thiab muaj kev xav tau sai rau lub cim tshiab ntawm kev txhim kho kom ruaj khov ntawm lub peev xwm loj heev.Qhov "sustainability" no feem ntau yog tshwm sim nyob rau hauv ob yam: thawj, muaj peev xwm sustainability: Lub zog muaj peev xwm tuaj yeem hloov kho tsis tu ncua thiab ua haujlwm zoo kom tau raws li kev lag luam loj hlob xav tau ntawm cov neeg ua haujlwm rau lub sijhawm tseem ceeb yav tom ntej;Thib ob, kho vajtse sustainability: Muaj peev xwm hloov khoom dua tshiab tsis tas yuav hloov cov khoom siv uas twb muaj lawm, thiab txhua yam khoom siv tuaj yeem siv tsis tu ncua, txo qhov cuam tshuam ntawm kev hloov kho tshiab ntawm kev lag luam.
