Ib lub network hloov yog ib qho khoom siv me me uas nruab nrab ntawm kev sib txuas lus ntawm ntau cov khoom sib txuas hauv ib cheeb tsam hauv cheeb tsam (LAN).
Stand-alone Ethernet hloov khoom siv tau nquag siv hauv tsev network ntau xyoo ua ntej lub tsev broadband routers nrov. Cov routers hauv tsev niaj hnub sib koom ua ke Ethernet hloov ncaj qha rau hauv chav tsev ua ib qho ntawm lawv cov haujlwm tseem ceeb.
Kev ua haujlwm siab network hloov pauv tseem siv dav hauv cov koom tes sib koom tes thiab cov chaw khaws ntaub ntawv. Lub network keyboards qee zaum hu ua switching hubs, bridging hubs lossis MAC txuas hniav.
About Network Switches
Ethernet keyboards yog hom ntau tshaj plaws, tab sis koj tseem yuav pom cov keyboards optimized rau ATM, Fiber Channel, thiab Token Ring network architectures.
Mainstream Ethernet keyboards zoo li cov nyob hauv broadband routers txhawb Gigabit Ethernet nrawm rau ib tus neeg txuas, tab sis cov kev ua haujlwm siab zoo li cov hauv cov chaw zov me nyuam feem ntau txhawb 10 Gbps ib qhov txuas.
Cov qauv sib txawv ntawm lub network hloov pauv txhawb ntau tus lej ntawm cov khoom siv sib txuas. Cov neeg siv-qib network hloov pauv muab plaub lossis yim kev sib txuas rau Ethernet cov khoom siv, thaum cov neeg siv hloov pauv feem ntau txhawb nqa ntawm 32 thiab 128 kev sib txuas.
Hloov pauv kuj txuas rau ib leeg, txoj kev daisy chaining, ntxiv cov khoom siv ntau dua mus rau LAN.
Managed and Unmanaged Switches
Basic network keyboards zoo li cov siv hauv cov neeg siv khoom routers yuav tsum tsis muaj kev teeb tsa tshwj xeeb tshaj li ntsaws rau hauv cables thiab lub zog.
Piv rau cov hloov pauv tsis tau tswj hwm, cov khoom siv siab kawg siv rau hauv kev lag luam tes hauj lwm txhawb nqa ntau yam ntawm cov yam ntxwv siab heev uas tsim los tswj los ntawm tus thawj coj tshaj lij. Cov yam ntxwv nrov ntawm kev tswj cov keyboards suav nrog SNMP saib xyuas, txuas txuas, thiab QoS kev txhawb nqa.
Ib txwm, cov keyboards tswj tau tsim los tswj los ntawm Unix-style hais kom ua kab interfaces. Ib pawg tshiab ntawm kev tswj cov keyboards hu ua cov keyboards ntse, tsom rau ntawm kev nkag-theem thiab nruab nrab cov tuam txhab lag luam, txhawb nqa web-based interfaces zoo ib yam li lub tsev router.
Network Hloov vs. Hubs thiab Routers
Ib lub network hloov lub cev zoo ib yam li lub network hub. Tsis zoo li cov hubs, txawm li cas los xij, lub network hloov pauv muaj peev xwm tshawb xyuas cov lus xa tuaj thaum lawv tau txais thiab coj lawv mus rau qhov chaw sib txuas lus tshwj xeeb-ib lub tshuab hu ua pob ntawv hloov.
Ib qho kev hloov pauv txiav txim siab qhov chaw nyob thiab qhov chaw nyob ntawm txhua pob ntawv thiab xa cov ntaub ntawv tsuas yog rau cov khoom siv tshwj xeeb, thaum lub hubs xa cov pob ntawv mus rau txhua qhov chaw nres nkoj tshwj tsis yog ib qho uas tau txais cov tsheb khiav. Nws ua haujlwm li no txhawm rau txuag lub network bandwidth thiab feem ntau txhim kho kev ua haujlwm piv rau hubs.
Hloov pauv kuj zoo li lub network routers. Thaum lub routers thiab hloov ob qho tib si hauv nruab nrab ntawm kev sib txuas hauv zos, tsuas yog routers muaj kev txhawb nqa rau kev cuam tshuam rau sab nraud, xws li hauv zos network lossis internet.
Txheej 3 Hloov
Cov kev sib txuas sib txuas sib txuas ua haujlwm ntawm Txheej 2 Cov Ntaub Ntawv Txuas Txheej Txheej ntawm OSI qauv. Txheej 3 cov keyboards uas muab cov khoom siv sab hauv ntawm cov keyboards thiab routers rau hauv cov khoom siv sib xyaw kuj tau muab tso rau ntawm qee lub lag luam network.
Piv rau cov keyboards ib txwm muaj, Txheej 3 keyboards muab kev txhawb nqa zoo dua rau kev teeb tsa LAN virtual.
FAQ
KVM keyboards yog dab tsi?
A KVM hloov yog ib qho khoom siv uas tso cai rau koj los tswj ntau lub khoos phis tawj siv ib tus saib thiab keyboard. Koj tseem tuaj yeem ntxiv cov saib thiab cov keyboards ntxiv rau koj qhov teeb tsa.
Tus hloov pauv VPN yog dab tsi?
Qee lub vev xaib ntiag tug virtual (VPNs) muaj qhov hloov pauv software uas cia li cuam tshuam kev siv internet thaum koj txiav tawm. Cov yam ntxwv no ua kom koj qhov chaw nyob IP thiab lwm yam ntaub ntawv tus kheej yuav tsis raug.
Puas tau hloov pauv lub network txo qis?
Yog, tab sis tsis txaus los ua kom pom qhov sib txawv. Ib yam li cov kab txuas ntev ntxiv ntxiv me ntsis latency, cov keyboards ntxiv kuj ntxiv qhov tsis txaus ntseeg ntawm latency. Yog tias koj qhov kev sib txuas hauv Is Taws Nem qeeb, nws tsis muaj dab tsi cuam tshuam nrog cov keyboards yog tias txhua yam txuas tau zoo.
Tus nqi network hloov pauv li cas?
Tus nqi ntau heev los ntawm qis dua $ 40 txog $ 500 nyob ntawm qhov feem ntau ntawm cov chaw nres nkoj thiab cov yam ntxwv ntxiv. Rau 20-chaw nres nkoj network hloov, koj tuaj yeem cia siab tias yuav them $ 150- $ 250.
