Yuav faib thiab xaiv cov keyboards li cas?

Cov keyboards tau siv dav hauv cov phiaj xwm tsis muaj zog tam sim no, thiab txhua hom kev sib kis ntawm cov ntaub ntawv tsis sib cais los ntawm lawv. Hnub noJHA Techyuav tham txog kev faib tawm thiab kev xaiv cov khoom siv ntawm cov keyboards.

1. Kev faib tawm ntawm cov keyboards
2. 1-1 Raws li cov qauv hauv lub network: nws muab faib ua cov txheej txheem nkag, cov txheej txheem sib txuas thiab cov txheej txheem tseem ceeb.

1-2 Raws li OSI qauv: nws muab faib ua txheej 2 keyboards, txheej 3 keyboards, txheej 4 keyboards, thiab lwm yam, txhua txoj kev mus rau txheej 7 keyboards.

1-3 Kev Tswjhwm ntawm cov keyboards: Qhov sib txawv ntawm cov keyboards tswj thiab tsis tswj cov keyboards nyob rau hauv lawv cov kev txhawb nqa rau network tswj raws tu qauv xws li SNMP thiab RMON.

JHA Tech, yog cov chaw tsim khoom qub tau mob siab rau R&D, ntau lawm, thiab muag Ethernet Hloov, Media Converter, PoE Hloov & Txhaj Tshuaj thiab SFP module thiab ntau yam khoom lag luam rau 17 xyoo. Txhawb OEM, ODM, SKD thiab lwm yam.

Kuj tseem muaj cov khoom lag luam ua tiav, pab pawg R & D muaj zog, kev teb sai tom qab kev muag khoom, thiab kev paub daws teeb meem kev thov.

JHA Tech muaj pab pawg kws tshaj lij tshaj lij ntawm ntau dua 20 tus neeg nrog kev ua haujlwm nruab nrab ntawm ntau dua 15 xyoo, thiab tuaj yeem daws koj qhov teeb meem tsis pub dhau 30 feeb ntawm qhov ceev tshaj plaws.

2.Main reference yam tseem ceeb rau kev xaiv hloov

a.Backplane bandwidth, Txheej 2/3 switching throughput.

b.VLAN hom thiab tus lej.

c.Number thiab hom hloov chaw nres nkoj.

d. Txhawb kev tswj hwm kev sib txuas lus thiab cov txheej txheem. Cov keyboards yuav tsum tau muab kom yooj yim dua thiab kev tswj hwm hauv nruab nrab.

e, Qos, 802.1q qhov tseem ceeb tswj, 802.1X, 802.3X kev txhawb nqa.

f. Kev pab txhawb nqa.

g.Switching cache, chaw nres nkoj cache, lub cim xeeb loj, kev xa mus qeeb thiab lwm yam tsis muaj.

h.Line ceev xa mus, routing rooj loj, nkag mus tswj daim ntawv teev loj, kev txhawb nqa rau routing raws tu qauv, kev them nyiaj yug rau multicast raws tu qauv, packet filtering txoj kev, tshuab expansion peev, thiab lwm yam yog tag nrho cov tsis tsim nyog xav txog thiab yuav tsum tau soj ntsuam raws li qhov tseeb qhov teeb meem.

Yog tias koj xav tau kev daws teeb meem ntawm kev xaiv qhov hloov pauv, thov tso koj tus email chaw nyob thiab peb yuav muaj tus kws tshaj lij hu rau koj rau cov lus teb ib leeg.
