Dab tsi yog qhov hloov pauv tswj tau?
Lub luag haujlwm tseem ceeb ntawm kev tswj kev hloov pauv yog ua kom tag nrho cov peev txheej hauv network nyob rau hauv qhov xwm txheej zoo. Nws muab ntau txoj hauv kev tswj hwm lub network, xws li cov chaw nres nkoj raws li kev tswj hwm, Web tswj, network tswj software, thiab lwm yam, kom cov thawj coj hauv network tuaj yeem saib xyuas kev ua haujlwm thiab kev ua haujlwm hauv zos lossis nyob deb. Tswj cov ntaub ntawv hloov pauv yuav raug teeb tsa los ntawm kev siv SNMP, xa cov ntaub ntawv teeb tsa mus rau cov kws tshaj lij network, uas ua rau kev daws teeb meem yooj yim dua thaum txhim kho lub sijhawm.
Cov yam ntxwv ntawm kev tswj kev hloov pauv nrog kev tswj xyuas tag nrho thiab kev saib xyuas muaj peev xwm suav nrog:
Nws tuaj yeem siv rau hauv ntau qhov sib txawv ntawm cov qauv hauv network, suav nrog Spanning Tree Protocol, nplhaib, mesh, stacking, thiab aggregation, kom rov ua dua thiab kev vam khom.
Ntau yam kev ruaj ntseg muaj nyob rau hauv qhov chaw los saib xyuas kev nkag mus rau hauv lub network, txheeb xyuas qhov muaj peev xwm tawm tsam, thiab kho txhua qhov kev ua txhaum cai ruaj ntseg.
Lub kaw lus tuaj yeem txhim kho kev ua tau zoo ntawm cov khoom siv thiab cov ntawv thov hauv lub network los ntawm Kev Pabcuam Zoo (QoS), uas yog qhov tseem ceeb ntawm kev khiav tsheb thiab pab pawg ntaus ntawv hom nrog cov kev pabcuam.
Dab tsi yog qhov hloov pauv tsis tau tswj hwm?
Unmanaged keyboards yuav tsum tsis muaj ntxiv configuration siv. Thaum ib tus neeg siv ntsaws rau hauv hom kev hloov no, lawv tam sim ntawd pib xa mus.
Cov yam ntxwv ntawm kev tswj tsis tau hloov pauv muaj xws li:
Kev siv tau tsuas yog siv rau kev sib txuas lus yooj yim xws li lub hnub qub thiab daisy chains.
Muaj peev xwm tsim thiab khaws MAC chaw nyob cov rooj, ua kom muaj kev tswj xyuas tsheb zoo dua li siv Ethernet hub.
Tsis muaj qhov sib txawv ntawm txoj kev keyboards tswj cov tsheb khiav ntau thiab kev tshaj tawm xov xwm, uas tuaj yeem ua rau muaj teeb meem loj heev hu ua cua daj cua dub (tshwj xeeb yog muaj teeb meem nrog cov khoom siv IoT, uas feem ntau vam khom ntau lub tsheb los ua cov lus txib hais txog cov cuab yeej)
Tswj vs. Unmanaged Hloov: Qhov Tseem Ceeb Qhov txawv
Cov lus hauv qab no teev qhov sib txawv ntawm ntau yam ntawm kev tswj thiab tsis tswj cov keyboards:

| Rov qab | Muab redundancy kom txo qis downtime | Tsis muaj redundancy nta |
| Kev faib Bandwidth | Kev faib tawm bandwidth yuav raug txwv thiab tuaj yeem hloov kho | Sib koom bandwidth, tsis siv neeg faib |
| Group Management Protocol (IGMP) | Feem ntau txhawb IGMP txhawm rau txhim kho kev ua haujlwm network | Tsis txhawb IGMP, tsis muaj peev xwm tswj tau ntau lub tsheb khiav |
| Nqi | Cov nqi tuaj yeem pheej yig, nyob ntawm seb muaj pes tsawg tus chaw nres nkoj hauv qhov hloov | Tswj cov keyboards yog kim dua, nyob ntawm seb cov yam ntxwv tshwj xeeb, thiab muaj cov neeg ua haujlwm cov nqi los xav txog |
| Daim ntawv thov | Loj/Government Organization/Commercial Business | Tsev/Drmitory/Small Business |

Kev sib piv ntawm cov tswj tswj thiab tsis tswj cov keyboards
Managed vs. Unmanaged Hloov: Yuav ua li cas xaiv tus hloov txoj cai?
Xaiv txoj kev hloov tsis yog qhov nyuaj li koj xav. Tau kawg, koj tuaj yeem sab laj ob tus kws tshaj lij network cov thawj coj thiab cov muag khoom siv network. Txawm li cas los xij, kuv xav tias koj qhov kev txiav txim siab yuav zoo dua tom qab xav txog cov hauv qab no.
Yuav xaiv txoj cai hloov li cas
1. Network loj
Yog tias koj xav siv cov cuab yeej no rau lub chaw ua haujlwm me me lossis lub network hauv tsev thiab xav tau kev ua haujlwm yooj yim, cov keyboards tsis tswj xyuas yuav txaus.
Txawm li cas los xij, cov kev tswj xyuas tau zoo dua rau cov koom haum nruab nrab mus rau cov koom haum loj, tshwj xeeb tshaj yog cov uas yuav tsum tau muaj kev ruaj ntseg thiab kev saib xyuas network, xws li tsoomfwv cov koom haum, tsev kawm qib siab, thiab lwm yam.
2. Network Yuav tsum tau
Kev tswj cov keyboards yog qhov kev xaiv zoo thaum koj muaj kev xav tau siab rau kev tswj xyuas network, saib xyuas, thiab kev ruaj ntseg.
Ntawm qhov tsis sib xws, yog tias koj tsis xav tau cov khoom siv network ntau, tsis muaj kev paub dhau los hauv kev tswj hwm lub network, thiab muaj peev nyiaj tsawg, qhov kev hloov tsis tau tswj xyuas yuav zoo dua.
3. Yav tom ntej scalability
Yog tias koj lub network yuav nthuav dav ntxiv rau yav tom ntej, cov keyboards tsis muaj kev tswj hwm yuav tsis tuaj yeem ua tau raws li qhov xav tau ntawm lub network thiab yuav ua rau muaj teeb meem xws li kev ua haujlwm tsis zoo hauv lub network. Los ntawm kev xaiv qhov hloov pauv, koj tuaj yeem yooj yim dua rau yav tom ntej network nthuav dav thiab kev hloov kho thev naus laus zis.
4. Tus nqi
Cov peev nyiaj kuj yog ib qho tseem ceeb hauv kev txiav txim siab qhov twg koj yuav tsum xaiv. Cov keyboards tswj tau kim dua thiab xav tau kev siv nyiaj zoo. Unmanaged keyboards tso cai rau koj los daws koj cov khoom siv network kev yuav khoom nrog kev siv nyiaj me me.
