Nrog rau kev loj hlob sai ntawm cov khoos phis tawj thiab lawv cov kev sib txuas thev naus laus zis (tseem hu ua "network technology"), Ethernet tau dhau los ua qhov luv luv-ntau ob-txheej khoos phis tawj network nrog qhov nkag siab tshaj plaws txog tam sim no.Qhov tseem ceeb ntawm Ethernet yog Ethernet hloov.
Kev tuav tswj thiab kev tswj hwm kev hloov pauv yog siv los xa cov suab paj nruag thiab yog "circuit switching" uas yuav tsum muaj cov kab tshwj xeeb.Ethernet yog lub khoos phis tawj uas xav tau los sib qhia cov ntaub ntawv, yog li nws siv "packet switching."Txawm li cas los xij, tsis hais qhov kev hloov pauv twg tau txais, qhov hloov pauv yuav muab "kev nkag tau tshwj xeeb" ntawm ob lub ntsiab lus.Raws li Ethernet cov cuab yeej muaj kev txhawj xeeb, qhov sib txawv tseem ceeb ntawm qhov hloov pauv thiab lub hub yog tias thaum A xa lus mus rau B, yog tias nws dhau los ntawm lub hub, txhua lub network nodes nkag mus rau lub hub yuav tau txais cov lus (uas yog, nws yog. xa hauv daim ntawv tshaj tawm), tab sis daim npav network yuav lim tawm cov ntaub ntawv tsis xa mus rau lub tshuab hauv zos ntawm qib kho vajtse;Yog tias qhov hloov pauv tau siv, tshwj tsis yog A ceeb toom qhov hloov mus rau kev tshaj tawm, cov lus xa mus rau B yuav tsis tau txais los ntawm C (tshwj tsis yog tau txais kev tso cai hloov pauv los saib xyuas).
Ethernet hloov chaw tsim khoom tau qhia txheej 3 lossis txawm tias txheej 4 hloov raws li kev lag luam xav tau.Txawm li cas los xij, nws lub luag haujlwm tseem ceeb tseem yog Ethernet pob ntawv hloov pauv ntawm txheej thib ob, nrog lub peev xwm los tswj cov txheej txheem IP thiab cov pob ntawv ntau dua.Lub network hloov yog ib qho cuab yeej los nthuav lub network, muab ntau qhov chaw sib txuas rau lub subnetwork los txuas ntau lub khoos phis tawj.Kev ua lag luam rau kev hloov pauv hauv network tau nce tsis tu ncua;Nrog rau txoj kev loj hlob ntawm kev lag luam kev sib txuas lus thiab kev txhawb nqa cov ntaub ntawv xov xwm ntawm lub teb chaws kev lag luam, qhov kev xav tau ntawm kev hloov pauv hauv lub network tau nce tsis tu ncua.Nws muaj qhov sib piv ntawm tus nqi siab thiab kev ua haujlwm siab, uas yog qhov yooj yim thiab siv tau yooj yim.
Cov saum toj no yog qhov kev paub piav qhia ntawm Ethernet Hloov coj los ntawmShenzhen HDV Phoelectron Technology Co., Ltd., Yog tias koj xav nrhiav qee qhov muag kub EthernetHloov, Thov mus saibethernet hloovnplooj.
Cov khoom uas tau hais los saum no tuaj yeem txhawb nqa ntau yam kev teeb tsa network.Peb lub lag luam yog outfitted nrog ib pab neeg ua lag luam muaj peev xwm thiab kev tshaj lij los muab cov kev pabcuam zoo rau cov neeg siv khoom 'kev sib tham thawj zaug thiab ua haujlwm tom qab, nrog rau cov kws tshaj lij thiab muaj zog R & D pab neeg los txhawb cov neeg siv khoom technically.
