Qhov sib txawv ntawm Txheej 2 thiab Txheej 3 network hloov
Txhua tus paub ib yam dab tsi txog Layer 2 thiab Layer 3 networks, tab sis koj paub ntau npaum li cas txog qhov sib txawv ntawm lawv?JHATechr yuav coj koj hla nws.
- Txheej 2
Layer2 network qauv hom nrog tsuas yog txheej txheej thiab nkag txheej yooj yim rau kev khiav lag luam. Qhov hloov mus xa cov ntaub ntawv pob khoom raws li MAC chaw nyob cov lus.
Yog tias muaj, nws yuav raug xa mus, yog tias tsis yog, nws yuav raug dej nyab, uas yog, cov ntaub ntawv yuav raug xa mus rau txhua qhov chaw nres nkoj. Yog tias lub davhlau ya nyob twg tau txais cov lus teb, qhov hloov pauv tuaj yeem ntxiv qhov chaw nyob MAC rau lub rooj chaw nyob. Qhov no yog qhov hloov pauv tsim qhov chaw nyob MAC. txheej txheem.
Txawm li cas los xij, qhov kev tshaj tawm tsis tu ncua ntawm cov ntaub ntawv pob ntawv nrog MAC lub hom phiaj tsis paub yuav ua rau muaj cua daj cua dub loj hauv lub network loj loj. Qhov no kuj txwv kev nthuav dav ntawm cov txheej txheem thib ob. Yog li ntawd, Layer2 network Lub peev xwm sib txuas lus muaj tsawg heev, yog li lawv feem ntau tsuas yog siv los tsim cov LANs me me.
- Txheej 3
Sib txawv ntawm Layer2 network, Laye3 network qauv tuaj yeem sib sau ua ke hauv cov tes hauj lwm loj.
Cov txheej txheem tseem ceeb yog cov pob txha txhawb nqa thiab cov ntaub ntawv xa tawm ntawm tag nrho lub network, thiab nws qhov tseem ceeb yog qhov tseeb.
Yog li ntawd, nyob rau hauv tag nrho Layer3 network qauv, cov tub ntxhais txheej muaj cov khoom siv siab tshaj plaws. Nws yuav tsum tau nruab nrog cov ntaub ntawv ua tau zoo redundant hloov khoom siv thiab cov khoom siv sib npaug kom tsis txhob overload, thiaj li yuav txo tau cov ntaub ntawv nqa los ntawm txhua tus tub ntxhais txheej hloov.
JHA Tech, yog cov chaw tsim khoom qub tau mob siab rau R & D, ntau lawm, thiab muag khoomEthernet Hloovs, Media Converter, PoE Hloov & Injector thiabSFP modulethiab ntau yam khoom lag luam rau 17 xyoo. Txhawb OEM, ODM, SKD thiab lwm yam.
Lub software txhawb nqa JHA Tech tswj cov keyboards, L2 thiab L3 yog tib lub software ua haujlwm, uas coj kev yooj yim rau cov neeg siv khoom. Daim duab saum toj no qhia txog kev hloov kho ua haujlwm uas JHA Tech tuaj yeem ua tiav nrog software interface.
BUGs tsa ntawm qhov chaw tuaj yeem kho tsis pub dhau 30 feeb thaum ntxov. Cov yam ntxwv tshiab thov los ntawm cov neeg siv khoom tuaj yeem raug tso tawm raws li pob khoom hloov kho hauv 7 hnub thaum ntxov. Yuav tsis muaj nqi kho dua tshiab ntxiv.
Koj puas muaj lus nug txog kev siv Switch, lossis xav yuav ntau tus qauv kom nyiam cov neeg siv khoom? Yog tias koj xav tau kev pab, thov tso koj tus email chaw nyob thiab peb yuav muaj tus kws tshaj lij hu rau koj rau cov lus teb ib leeg.
