Ua ntej nkag siab txog VLAN cais kev ua haujlwm ntawm lubhloov, peb xub nkag siab Ethernethloov: Ethernethloovyog ahloovraws li Ethernet cov ntaub ntawv xa mus. Txhua qhov chaw nres nkoj ntawm Ethernethloovtuaj yeem txuas nrog tus tswv tsev, feem ntau ua haujlwm nyob rau hauv full-duplex hom, thiab tuaj yeem txuas rau qhov chaw nres nkoj ntawm tib lub sijhawm, kom txhua khub ntawm cov khoom siv sib txuas lus tuaj yeem sib txuas lus tsis muaj kev cuam tshuam rau ib leeg.
VLAN yog hais txog lub network hauv zos virtual, yog ib pawg ntawm cov cuab yeej siv thiab cov neeg siv, kev sib txuas lus ntawm pab pawg ntawm cov cuab yeej siv no thiab cov neeg siv zoo sib xws hauv tib lub network ntu, tuaj yeem sib txawv qhov chaw sib txawv, sib txawv network, sib txawv cov neeg siv ua ke los tsim ib lub virtual. network ib puag ncig, ib yam li kev siv LAN hauv zos kom yooj yim, hloov tau, siv tau. VLAN tuaj yeem txo tus nqi tswj kev txav lossis hloov qhov chaw ntawm chaw ua haujlwm, tshwj xeeb tshaj yog rau qee lub tuam txhab uas muaj kev hloov pauv ntau zaus hauv kev lag luam, qhov no ntawm cov nqi tswj tau txo qis heev.
Kev rho tawm Vlan yog ua tau raws li lub luag haujlwm ntawm Vlan thev naus laus zis, los ntawm Vlan faib ntawm cov chaw nres nkoj sib txawv, cov khoom siv terminals, cov neeg siv kom ua tiav kev sib cais ntawm cov ntaub ntawv lag luam. Tsis tas li ntawd, kev cais tawm Vlan tuaj yeem ua raws li qhov chaw nres nkoj ntawm lubhloovVlan muab faib rau kev sib txuas sib txuas, kuj tuaj yeem ua raws li IP Vlan muab faib rau kev sib txuas sib txuas Ethernethloovraws li VLAN thev naus laus zis, koj tuaj yeem tsim ntau yam LAN, hauv lub neej tiag tiag, xav tsim kom muaj qhov sib txawv LAN rau txhua qhov chaw nres nkoj, Piv txwv li, R&D department, chaw ua lag luam, chaw ua haujlwm, thiab lwm yam, ntawm tib lub tuam txhab.
Ua tsaug rau kev tshuaj xyuas qhov qhia txog VLAN kev cais tawm ntawm Ethernethloovcoj los ntawm Shenzhen Haidiwei Optoelectronic Technology Co., LTD., Pebhloovkhoom series, kuj npog ib tug xov tooj ntawm specifications ntawm lubhloov, xws li: txhua qhov chaw kho qhov muaghloov,,8 port ibhloov, 100 MEGAbithloov, kev tswj networkhloovthiab lwm yam, txais tos tuaj xyuas.
