Kev Tswj Bandwidth hauv Networks
Pendahuluuan
Nyob rau hauv lub caij nyoog digital niaj hnub no, qhov xav tau kev sib txuas lus network ceev thiab txhim khu kev qha tau dhau los ua qhov tseem ceeb heev. Txawm hais tias rau cov kev xav tau ntawm tus kheej xws li kev tshaj tawm video lossis cov koom haum ua lag luam txhua hnub, kev muaj bandwidth txaus yog qhov tseem ceeb. Yog li ntawd, kev tswj hwm bandwidth hauv lub network yog qhov tseem ceeb kom ntseeg tau tias cov peev txheej network tau siv kom zoo li sai tau. Tsab xov xwm no yuav tham txog bandwidth thiab kev tswj hwm bandwidth, nws qhov tseem ceeb, cov txheej txheem, thiab cov cuab yeej siv feem ntau hauv kev tswj hwm bandwidth network.
Bandwidth yog dab tsi?
Hauv kev sib txuas lus hauv network, bandwidth yog qhov ntsuas ntawm cov ntaub ntawv uas tuaj yeem xa mus los ntawm ib qho chaw mus rau lwm qhov hauv ib lub sijhawm. Cov chav ntsuas rau bandwidth feem ntau yog bits ib ob (bps), kilobits ib ob (kbps), megabits ib ob (Mbps), lossis gigabits ib ob (Gbps). Peb tuaj yeem xav txog bandwidth ua qhov dav ntawm txoj kev loj: qhov dav dua txoj kev loj, qhov ntau lub tsheb (cov ntaub ntawv) tuaj yeem hla tib lub sijhawm.
Vim li cas kev tswj hwm Bandwidth thiaj tseem ceeb?
Kev tswj hwm bandwidth yog tus txheej txheem ntawm kev tswj hwm thiab tswj hwm kev faib bandwidth hauv lub network kom ntseeg tau tias siv tau zoo thiab ncaj ncees. Yog tsis muaj kev tswj hwm zoo, cov network tuaj yeem ntsib ntau yam teeb meem, xws li kev sib txuas qeeb, kev tsis sib haum xeeb, thiab lub sijhawm tsis ua haujlwm, uas tuaj yeem cuam tshuam tsis zoo rau kev tsim khoom ntawm lub koom haum thiab kev nplij siab ntawm cov neeg siv ib tus zuj zus. Qee qhov laj thawj tseem ceeb vim li cas kev tswj hwm bandwidth tseem ceeb yog:
1. Kev Txhim Kho Cov Khoom Siv Hauv Network: Xyuas kom meej tias muaj bandwidth rau cov ntawv thov thiab cov kev pabcuam uas xav tau nws tshaj plaws.
2. Tiv Thaiv Kev Siv Network Ntau Dhau: Txo qhov kev pheej hmoo ntawm kev siv network ntau dhau uas tuaj yeem ua rau kev ua haujlwm poob qis.
3. Txhim Kho Kev Ruaj Ntseg: Txheeb xyuas thiab daws cov haujlwm hauv network uas tsis raug cai lossis tsis tau tso cai.
4. Kev Paub Zoo Dua Rau Tus Neeg Siv: Xyuas kom muaj kev pabcuam zoo dua (QoS) rau cov kev siv tiag tiag xws li VoIP thiab kev tshaj tawm video.
Cov Txheej Txheem Tswj Bandwidth
Muaj ntau txoj kev siv tau rau kev tswj hwm bandwidth, ntawm no yog qee qhov feem ntau siv:
1. Kev Pabcuam Zoo (QoS)
QoS yog ib txoj kev tswj bandwidth uas tsim los kom ntseeg tau tias cov ntawv thov tseem ceeb tau txais qhov tseem ceeb dua hauv kev siv bandwidth. Piv txwv li, hauv ib lub koom haum, VoIP hu thiab video streaming yuav raug muab qhov tseem ceeb dua li kev tshawb nrhiav hauv web.
2. Kev Tswj Bandwidth
Kev txwv tsis pub siv bandwidth yog ib txoj kev uas txwv qhov ceev ntawm kev sib txuas rau cov khoom siv lossis cov ntawv thov tshwj xeeb kom tiv thaiv kev siv bandwidth ntau dhau. Piv txwv li, cov neeg siv tuaj yeem teeb tsa qhov ceev tshaj plaws ntawm kev rub tawm ntawm cov ntawv thov sib koom cov ntaub ntawv kom txo qhov kev siv bandwidth.
3. Kev Tsim Tsheb
Kev tsim cov ntaub ntawv khiav yog ib txoj kev siv uas tswj cov ntaub ntawv kom tsis txhob muaj cov ntaub ntawv ntau dhau uas ua rau lub network puv dhau. Cov ntaub ntawv raug tswj kom nws ntws sib npaug dua hauv ib lub sijhawm tshwj xeeb.
4. Kev lim cov ntaub ntawv
Kev lim cov ntaub ntawv (packet filtering) yog ib txoj kev siv los tswj cov hom ntaub ntawv uas hla tau hauv lub network. Los ntawm kev lim cov ntaub ntawv raws li hom, keeb kwm, lossis qhov chaw mus, lub network tuaj yeem ua kom zoo dua thiab muaj kev nyab xeeb.
5. Kev Saib Xyuas Network
Kev saib xyuas network yog cov txheej txheem txuas ntxiv ntawm kev saib xyuas thiab tshuaj xyuas cov haujlwm hauv network. Yog tias muaj kev saib xyuas kom zoo, cov thawj coj network tuaj yeem txheeb xyuas thiab daws cov teeb meem sai sai ua ntej lawv nce siab.
Cov Cuab Yeej Tswj Bandwidth
Muaj ntau yam cuab yeej siv tau rau kev tswj bandwidth, ob qho tib si hardware thiab software. Qee cov cuab yeej nrov suav nrog:
1. MikroTik Router
MikroTik yog ib lub cuab yeej networking uas paub zoo txog nws cov peev xwm tswj bandwidth. Nrog rau cov yam ntxwv xws li QoS, kev teeb tsa cov ntaub ntawv, thiab kev tswj bandwidth, MikroTik feem ntau siv rau hauv cov koom haum me thiab nruab nrab.
