Kuj muaj qee yam li ntawd Gigabit hloov, uas tau ntsia hauv cov txee rau neeg siv. Cov kws kho mob kuj muaj peev xwm yoog tau yooj yim thiab tsim cov kev sib txawv ntawm cov network sib txawv. Muaj twb xaiv ntau ntawm cov keyboards muaj hnub no thiab txhua tus neeg xaiv tau tus qauv zoo.

Ib tug haum ib Gigabit hloov yuav

Yuav yog ib qho tsim nyog dua Gigabit hloov ces kuj muaj qee yam los xav txog. Nws yog ib qho tseem ceeb, ntawm chav kawm, hais tias ib tug zoo zoo yog yuav. Muaj ntau tus neeg tuaj yeem xav kom siv hom lag luam zoo. Txawm hais tias zoo-paub manufacturers feem ntau me ntsis kim, ces sib raug zoo kev paub thiab zoo yog feem ntau muaj. Hauv yav dhau los, cov hub tau siv los tsim cov kev sib txuas sib txuas lus, thiab hnub no txoj haujlwm yog feem ntau ua los ntawm Gigabit keyboards saws. lub Gigabit hloov muaj lub zoo dua, ntawm chav kawm, hais tias qhov no yog txawj ntse. Tus qauv ua li no taw tes rau qhov twg lub davhlau ya nyob twg qhov kev tawm thiab ua rau tus taw tes uas tsim nyog, cov ntaub ntawv yog ces tsom. Yog tias siv lub hub, ces cov ntaub ntawv tsuas muab xa mus rau tag nrho cov kev tshaj tawm thiab yog li cov tsheb khiav mus ua haujlwm. Hais txog Gigabit hloov network pab kiag li lawm, cov tshuab luam ntawv, cov chaw zov me nyuam thiab cov PC yuav tsum txuas nrog. Cov cuab yeej siv tau ua hauj lwm hauv cov tes hauj lwm, yog li nyob hauv tsev network thiab ntxiv rau hauv cov chaw ua haujlwm. Rau Daheim feem ntau yog hloov me me thiab cov no yog pheej yig yuav thiab yuav muab rau lub network, uas ua haujlwm zoo.

Dab tsi nyob rau hauv kev yuav khoom ntawm lub Gigabit hloov xav txog?

Yeej lub Gigabit hloov hauv ntau ntau qhov sib txawv. Cov keyboards tau ntawm 2 thiab 50 cov chaw nres nkoj thiab qhov no yog nyob ntawm seb yuav tsum tau rau daim ntawv thov. Tseem ceeb thaum muas yog tias txhua qhov chaw yuav muab nthuav. Nws yuav tsum nyob rau hauv Gigabit hloov Nco ntsoov qee qhov chaw nres nkoj nyob dawb vim lawv pheej xav tau ib hnub tom qab. Rau cov lag luam loj, cov keyboards yog siv nrog lub siab ceev, uas yog txog 100 gigabit. Rau daim ntawv thov nyob tom tsev feem ntau me me ua qauv pom thiab nyob ntawm no nrog 100 Mbit ces Teeb Huab Hli. Ntawm qhov Gigabit hloov qhov kev kub ceev ces mam kuaj tau. Nws kuj tseem yuav kuaj tau seb nws yog ib yam khoom uas lub hwj huam mov tswj los ntawm PoE, lub koob thaij duab, IP xov tooj los yog lwm lub cuab yeej. Tseem ceeb heev rau qhov kev yuav khoom yog ib txwm muaj peev xwm hauv qab. Nws yuav tsum muaj tsawg kawg li high, raws li nrog tag nrho cov chaw nres nkoj qhov ntau dhau los yog. Feem ntau Gigabit hloov muaj peev xwm ntawm kev xa cov lab ntawm cov pob ntawv ib ob mus txog rau 1,6. Qhov tseem ceeb tshaj plaws yog tias cov pob khoom me me muaj peev xwm ua tau yooj yim dua li cov loj dua. Los ntawm cov ntaub ntawv cov ntaub ntawv, nws yog li tsuas yog yooj yim kom paub txog cov qauv siv nrog cov pob khoom loj.

Nkag mus rau cov servers nrog ceev ceev

ib tug Gigabit hloov yeej ib txwm ua ib qho tseem ceeb heev, yog hais tias tus neeg rau zaub mov nrog qhov ceev ceev yog siv los ntawm PC. Cov ntse qauv yog qhov zoo tshaj plaws haum rau cov ntawv no. Ntxiv rau qhov kev kub ceev muaj cov Gigabit hloov ntawm cov hoob kawm ntau lwm yam zoo. Feem ntau qhov no muaj xws li cov dynamic IP chaw nyob, kev Webkonfigurationsoberfläche, tau tej thaj chaw deb tswj ntawm SNMP thiab packets yuav routed los ntawm cov neeg tau kev pab qhov chaw nyob rau qhov kev tsim nyog qhov chaw nres nkoj. Rov qab ua nyees khawm kuj tseem yog ib qho kev ua ke. Nrog kev pab los ntawm ib lub pob, lub restart yog txhais thiab lwm yam yuav ua tau nyob rau Gigabit hloov lub koomhaum nqis. Qee cov qauv kuj muaj lub ports, uas yuav siv tau rau cov kev sib txuas ntawm fiber ntau li SFP cov chaw nres nkoj. Feem ntau cov qauv me me tsis muaj lawv tus kheej cov kiv cua tawm thiab yog li qhov kev lag luam yog ntsiag to. Puas muaj qhov loj dua Gigabit hloov ib tus kiv cua, ces khiav nrov nrov feem ntau yog kev poob siab tias yog cuam tshuam. Nrog rau kev txiav cov cuab yeej ua tiav cov ntaub ntawv muaj peev xwm tiav thiab txawm nrog cov khoom nruab nrab ntawm cov nqi nruab nrab ntawm qhov no twb muaj hnub no lawm. Nws yog feem ntau pom zoo tias nyob rau hauv Gigabit hloov raws li lub cuab yeej zoo siv nrog kev siv tshuab. Cov cuab yeej siv yuav tsum yog tsis muaj teeb meem-dawb, yog li ntawd cov khoom siv faulty tsis kis.

Qhov sib txawv qauv

Feem ntau cov qauv lus piav qhia twb pom cov khoom ntawm Gigabit hloov yog. Yog hais tias lub npe 48G yog nyob rau hauv lub npe, qhov no txhais tau hais tias, piv txwv li, tias 48 hosts party ports Gigabit hloov yog.

Cov lus qhia tseem ceeb txog qhov Gigabit hloov

Rau lub network, tus Hloov lub hauv paus tseem ceeb. Muaj cov cuab yeej Gigabit rau cov tes hauj lwm hauv tsev, cov kws lij choj, cov kws kho mob lub chaw ua hauj lwm lossis cov tuam txhab. Tsis muaj hloov lub wired networking ntawm network pab kiag li lawm, cov tshuab luam ntawv, cov servers thiab PCs tsis tau. Ib qho tseem ceeb nrog kev zoo Gigabit hloov yog hais tias tam sim no noj yog li tsawg li sai tau thiab txawm li ntawd los lub siab cov ntaub ntawv throughput yog coj. lub hloov yog ib qho txheeb ze ntawm lub hub. Yog vim li cas ntawm tus nqi, lawv tsuas yog siv ob peb xyoos dhau los, tab sis nyob rau lub sij hawm tam sim no xwb Hloov ua. Nyob rau hauv rooj plaub ntawd, intelligently txhais tau hais tias ntawm lub Gigabit hloov raws nraim paub cov cuab yeej twg txuas rau hauv qhov chaw nres nkoj thiab cov ntaub ntawv xa mus rau qhov chaw nres nkoj. Los ntawm lub hub, cov pob ntawv tsuas yog tig rau tag nrho cov chaw nres nkoj, ua qhov kev ruaj ntseg network tsis tau. Rau lub nraub qaum, qhov siab tshaj plaws nkag los ntawm cov neeg ua lag luam raws li qhov khoom ntawm cov xov tooj ntawm cov lag luam nrog GBit. Qhov chaw nres xya yim hloov li no muab 16 GBit ua daim phiaj rov qab los. Nrog Gigabit Ethernet chaw nres nkoj lub hloov txog 1,6 lab pob khoom hauv ib ob. Txawm li cas los xij, qhov me me rau cov pob khoom yog, qhov qis yog qhov dag zog. Tus nqi ntawm lub tuam txhab tsis tas yuav tsum hais ib yam dab tsi zoo li a hloov ces tiv nrog lub loj pob. Cov txiav-throuth technology muaj proven nws tus kheej nrog cov uas tsis muaj latency rau siab cov ntaub ntawv ntxiv rau thiab nws tuaj txog ib lub sij hawm ntev nyob rau hauv nruab nrab nqi ya. Txawm li cas los, ib tug drawback yog tias phem packets kuj yuav xa vim hais tias tsuas yog tom qab tau txais daim ntawv ntawm tag nrho cov ntaub ntawv tuaj rau lawv ib tug cyclic redundancy daim tshev los yog CRC daim tshev yog tau. Cov high-zoo qauv kuj muaj mechanism los yog coj Switching hu ua yuam kev-free txiav-los ntawm kev.
