Hauv lub ntiaj teb kev sib txuas ceev ceev uas cov ntaub ntawv ntws thiab kev sib txuas yog qhov tseem ceeb, kev hloov pauv hauv lub network yog cov pob txha ntawm kev sib txuas lus zoo. Todahike yog tus thawj coj hauv kev sib tham daws teeb meem, tsis tu ncua xa cov kev sib txuas hauv lub xeev mus rau lub zog lag luam thiab tsev. Kab lus no tshawb txog qhov hloov pauv ntawm kev hloov pauv hauv lub network thiab Todahike li cas yog nyob rau hauv pem hauv ntej ntawm kev nce qib thev naus laus zis no.
Keeb kwm ntawm Network Switches
Network hloov pauv tau tshwm sim thaum xyoo 1980s thiab thaum ntxov 1990s raws li kev hloov pauv ntawm lub network hubs. Tsis zoo li cov hubs, uas tshaj tawm cov ntaub ntawv rau txhua yam khoom siv sib txuas, cov keyboards tuaj yeem ntse ncaj qha cov ntaub ntawv rau cov khoom siv tshwj xeeb, ua kom muaj txiaj ntsig zoo hauv network thiab ceev. Todahike tau lees paub lub peev xwm ntawm cov thev naus laus zis no thaum ntxov thiab tau pib nws thawj cov kev hloov pauv hauv nruab nrab xyoo 1990, teeb tsa cov qauv tshiab rau kev ua tau zoo thiab kev ntseeg tau.
2000s: Qhov nce ntawm Gigabit Ethernet
Thaum ntxov 2000s, Gigabit Ethernet thev naus laus zis tau txais sai sai, ncav cuag qhov nrawm ntawm 1 Gbps. Qhov no yog ib qho tseem ceeb leap los ntawm ua ntej 100 Mbps Fast Ethernet tus qauv. Todahike tau pib ua ntau yam ntawm Gigabit keyboards kom tau raws li qhov kev thov loj dua rau bandwidth ntau dua hauv kev lag luam thiab hauv tsev network. Tsim los tswj cov ntaub ntawv loj hlob, cov keyboards no yooj yim txhawb kev siv xws li kev sib tham video, streaming media thiab cov ntaub ntawv loj.
2010s: Nkag mus rau lub sijhawm ntawm kev txawj ntse thiab tswj cov keyboards
Raws li kev tes hauj lwm dhau los ua nyuaj, qhov xav tau kom ntse dua, yooj yim-rau- tswj cov keyboards loj hlob. Todahike tau tshaj tawm cov kev tswj xyuas ntse uas muab cov thawj coj hauv lub network nrog kev tswj hwm ntau dua thiab pom tau. Cov keyboards no muaj cov yam ntxwv siab heev xws li kev txhawb nqa VLAN, Kev Pabcuam Zoo (QoS) qhov tseem ceeb, thiab txhim kho kev ruaj ntseg nta kom muaj txiaj ntsig zoo thiab kev ruaj ntseg network tswj.
Niaj hnub nimno era: puag 10 GB thiab siab dua
Nyob rau hauv xyoo tas los no, kev thawb rau kev nrawm dua thiab kev ua tau zoo dua tau ua rau kev txhim kho ntawm 10 Gb Ethernet (10GbE) keyboards. Todahike tau nyob rau hauv pem hauv ntej ntawm qhov kev hloov pauv no, pib lub cim tshiab ntawm cov keyboards tsim los ua kom tau raws li cov kev xav tau ntawm kev ua haujlwm siab niaj hnub. Cov 10GbE keyboards no zoo tagnrho rau cov chaw zov me nyuam cov ntaub ntawv, kev ua haujlwm siab hauv kev ua haujlwm, thiab cov lag luam uas xav tau cov ntaub ntawv hloov pauv ceev ceev thiab qis latency.
Todahike Kev cog lus rau Innovation
Todahike txoj kev vam meej hauv kev lag luam hloov pauv network yog vim nws txoj kev mob siab rau kev tsim kho tshiab thiab zoo. Lub tuam txhab tsis tu ncua nqis peev hauv kev tshawb fawb thiab kev tsim kho kom coj cov kev nce qib tshiab rau nws cov khoom. Todahike keyboards paub txog lawv qhov muaj zog, kev ua kom muaj zog, thiab lub zog ua haujlwm, ua rau lawv xaiv thawj zaug rau ntau yam kev siv.
Advanced nta rau lub ntiaj teb txuas
Todahike qhov hloov tshiab kawg tau nruab nrog ntau yam ntawm cov yam ntxwv siab heev tsim los ua kom tau raws li qhov xav tau ntawm cov kev sib txuas niaj hnub no:
High port density: Muab ntau qhov chaw nres nkoj kom haum rau kev loj hlob network.
PoE + Kev them nyiaj yug: Fais fab dhau Ethernet Plus (PoE +) ua kom muaj zog xws li IP koob yees duab, VoIP xov tooj, thiab cov ntsiab lus nkag wireless ncaj qha los ntawm Ethernet cable.
Kev ruaj ntseg siab tshaj: Cov yam ntxwv xws li kev nkag mus tswj cov npe (ACLs), chaw nres nkoj kev ruaj ntseg, thiab kev sib faib network tiv thaiv kev hem thawj hauv network.
Txhim kho kev tswj hwm: Lub vev xaib nkag siab yooj yim, kab lus hais kom sib txuas (CLI), thiab kev txhawb nqa rau kev tswj hwm network xws li SNMP ua kom yooj yim rau kev tswj hwm.
Redundancy thiab kev ntseeg tau: Cov yam ntxwv xws li Link Aggregation Control Protocol (LACP) thiab kev txhawb nqa rau cov khoom siv hluav taws xob rov ua dua kom paub meej lub sijhawm ua haujlwm thiab kev ntseeg tau.
Saib rau yav tom ntej
Raws li kev sib txuas lus txuas ntxiv mus ntxiv, Todahike tau npaj los ua txoj hauv kev nrog cov kev daws teeb meem tshiab kom tau raws li kev xav tau kev sib txuas ntxiv. Lub tuam txhab tab tom tshawb nrhiav lub peev xwm ntawm cov thev naus laus zis tshiab xws li 25GbE, 40GbE thiab 100GbE, nrog rau kev nce qib hauv software-txhais networking (SDN) thiab network ua haujlwm virtualization (NFV).
Nyob rau hauv luv luv, qhov tsis tu ncua nrhiav kev ceev dua, kev tswj kom zoo dua qub, thiab txhim kho kev ruaj ntseg tau tsav txoj kev loj hlob ntawm cov keyboards network. Todahike txoj kev mob siab rau kev tsim kho tshiab ua rau nws nyob rau hauv pem hauv ntej ntawm txoj kev loj hlob no, xa cov kev daws teeb meem uas pab cov lag luam thiab cov tib neeg ua tiav ntau dua. Raws li peb txav mus rau yav tom ntej, Todahike tseem cog lus tias yuav xa cov thev naus laus zis sib txuas ua ke uas txuas lub ntiaj teb sai dua, ntse dua, thiab muaj kev nyab xeeb dua.
