GigE, tseem hu ua Gigabit Ethernet, hais txog lub network thev naus laus zis uas muab cov ntaub ntawv xa mus ceev txog li 1 gigabit ib ob (Gbps). Nws yog tus qauv rau kev sib txuas ntawm Ethernet feem ntau siv hauv cheeb tsam hauv cheeb tsam (LANs) thiab thaj chaw dav dav (WANs).
Txhawm rau nkag siab qhov ceev ntawm GigE, cia peb tawg nws:
Chav ntsuas ntsuas:
Network speeds feem ntau yog ntsuas hauv cov khoom ib ob (bps). Lub prefix "Giga" sawv cev rau ib billion (10^9) units. Yog li, 1 Gbps txhais tau hais tias ib lab cov khoom tuaj yeem xa mus rau ib ob.
Sib piv rau lwm yam Networking Technologies:
GigE yog qhov nrawm dua li nws cov neeg ua ntej. Piv txwv li:
Fast Ethernet (100 Mbps): GigE yog kaum npaug sai dua Fast Ethernet.
Ethernet (10 Mbps): GigE yog ib puas npaug sai dua li tus qauv Ethernet.
Tus nqi Hloov cov ntaub ntawv:
Ntawm qhov ceev ntawm 1 Gbps, GigE tuaj yeem hloov 1, 000 megabits lossis 125 megabytes (MB) ntawm cov ntaub ntawv ib ob. Qhov no sib npaug rau:
Hloov cov ntaub ntawv 1 GB hauv kwv yees li 8 vib nas this.
Tshaj tawm cov ntsiab lus video siab yam tsis muaj buffering.
Kev xav txog kev ua tau zoo hauv ntiaj teb:
Thaum GigE muaj qhov theoretical siab tshaj plaws ceev ntawm 1 Gbps, qhov tseeb cov ntaub ntawv hloov pauv tuaj yeem qis dua vim muaj ntau yam:
Network congestion: Yog tias muaj ntau yam khoom siv sib koom hauv lub network, qhov muaj bandwidth tau muab faib rau lawv, txo tus neeg ceev.
Kev txwv cov khoom siv hauv lub network: Qhov zoo thiab muaj peev xwm ntawm lub network keyboards, routers, thiab network interface phaib tuaj yeem cuam tshuam kev ua haujlwm.
Cable zoo: Tsis zoo los yog puas cables tej zaum yuav ua rau qis speeds los yog nce yuam kev.
Network latency: Ceev ib leeg tsis suav rau latency, uas yog hais txog kev ncua ntawm kev xa thiab txais cov ntaub ntawv. Tsawg latency yog qhov tseem ceeb rau cov ntawv thov hauv lub sijhawm xws li kev sib tham video lossis kev ua si hauv online.
Advancements Beyond GigE:
Raws li thev naus laus zis zuj zus, cov qauv Ethernet nrawm dua tau tsim:
10 Gigabit Ethernet (10 Gbps): Muab kaum npaug ntawm qhov ceev ntawm GigE.
40 Gigabit Ethernet (40 Gbps) thiab 100 Gigabit Ethernet (100 Gbps): Feem ntau siv hauv kev ua haujlwm siab thiab cov chaw zov me nyuam.
Hauv cov ntsiab lus, GigE muab cov ntaub ntawv xa mus ceev ntawm 1 Gbps lossis ib billion khoom ib ob. Thaum nws qhov theoretical ceev yog qhov ua tau zoo, cov xwm txheej hauv ntiaj teb tuaj yeem cuam tshuam qhov kev ua tau zoo. Nws tau dav siv rau hauv zos thiab thoob plaws cheeb tsam network vim nws pheej yig thiab txhim kho tseem ceeb tshaj Ethernet qauv dhau los.
