Lub ntsiab lus ntawm cov txheej txheem yog daim ntawv qhia kev sib txuas lus ntawm kab ntawv, ob sab ntawm kev sib txuas lus yuav tsum tau sib koom ua ke ua cov ntaub ntawv sib kis raws li tus qauv no. Hauv kev sib txuas lus hauv computer, kev sib txuas lus raws tu qauv yog siv los paub txog kev sau npe ntawm lub khoos phis tawj thiab kev sib txuas hauv lub network, yog tias tsis muaj kev sib txuas lus sib koom ua ke, cov ntaub ntawv xa tawm ntawm cov khoos phis tawj tsis tuaj yeem txheeb xyuas, kev sib txuas lus raws tu qauv yog cov cai sib txuas lus pom zoo los ntawm ob sab ua ntej. Nws tuaj yeem nkag siab yooj yim raws li hom lus siv los ntawm khoos phis tawj sib tham
Cov txheej txheem txheej txheem hais txog cov kev siv tshwj xeeb ntawm cov txheej txheem, peb feem ntau hais lus yog lub tsev qiv ntawv ua haujlwm nrog cov cai, txhawm rau pab txhawb kev hu xov tooj ntawm tus tsim tawm. Cov txheej txheem txheej txheem yog cov lej ntawm cov txheej txheem hauv txhua txheej ntawm lub network, thiab nws cov duab qhia txog cov txheej txheem hloov ntaub ntawv hauv lub network. Los ntawm cov txheej txheem sab saud mus rau cov txheej txheem qis, thiab los ntawm cov txheej txheem qis mus rau sab sauv txheej txheem.
Network designers siv ib tug hierarchical network architecture, txheej txheem ntawm kev sib txuas lus ntawm ob tug tswv, nrog rau kev hloov khoom siv, raws tu qauv ua hauj lwm zoo li ib pawg, yog li nws yog hu ua raws tu qauv pawg.
Lub party a: Daim ntawv thov txheej- -> kis txheej - -> Network txheej- -> Cov ntaub ntawv txuas txheej- -> Lub cev txheej, cov tswv cuab b: Lub cev txheej - -> Cov ntaub ntawv txuas txheej - -> Network txheej- -> kis txheej- -> Daim ntawv thov txheej
Cov saum toj no yog cov lus piav qhia luv luv ntawm qhov sib txawv ntawm cov txheej txheem thiab cov txheej txheem txheej txheem coj los ntawm Shenzhen HDV Phoelectron Technology Co., LTD. Cov khoom siv sib txuas ntawm Shenzhen HDV Phoelectron Technology Co., LTD.. muaj software sib xws nrog peb cov khoom, cov khoom siv network no yogONUseries, kho qhov muag module series,OLTseries, transceiver series. Txais tos kom thov cov neeg ua haujlwm kom paub meej cov khoom nkag siab!
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.
16, Broadband thiab Dial-up
Peb tau siv ADSL broadband. ADSL: Asymmetric Digital Subscriber Kab.
Broadband yog siv los ntawm kev sib txuas ib lub xov tooj ntawm koj lub broadband cab kuj mus rau koj lub modem sab hauv tsev (feem ntau hu ua miv) thiab tom qab ntawd siv lub cable txuas rau lwm yam khoom siv hauv Internet.
Tom qab xyoo ntawm txoj kev loj hlob, ADSL tau dhau los ntawm peb tiam, los ntawm thawj ADSL mus rau tom qab txhim kho ADSL2 thiab tam sim no ADSL2+, qhov kev rub tawm tam sim no tuaj yeem ncav cuag 24M. ADSL siv zaus division multiplexing kom paub tias lub xov tooj teeb liab, uplink thiab downlink teeb liab tsis cuam tshuam ib leeg.
Niaj hnub no, kev siv fiber ntau rau hauv tsev (FTTH), tom qab tag nrho, lub teeb kis tau tus mob nrawm dua li qhov hluav taws xob sib kis ceev, muaj txiaj ntsig zoo dua. FTTH ua haujlwm los ntawm rub lub fiber ntau optic los ntawm cov cab kuj mus rau koj lub tsev thiab txuas mus rau lub teeb modem (feem ntau hu ua lub teeb miv). Tom qab ntawd siv Internet cable los ntawm lub teeb miv coj mus rau Is Taws Nem.
Dial-up Internet feem ntau yog hais txog PPPoe dial-up, uas yog ib txoj hauv kev nkag mus rau Is Taws Nem, ob qho tib si ADSL broadband dial-up (xov tooj kab sib txuas) thiab fiber ntau optic dial-up (fiber optic kis tau tus mob). PPPoe hais txog Point-to-Point Protocol Over Ethernet, uas txhais tau hais tias muaj ob lub cim ntawm cov neeg rau zaub mov thiab cov neeg siv khoom hauv qhov taw tes-rau-point raws tu qauv PPPoe hauv Is Taws Nem. Tus neeg teb xov tooj tau txais thiab xa cov ntaub ntawv mus rau cov neeg siv ntawm cov neeg siv tib yam li cov neeg rau zaub mov, uas yog ib-rau-ntau qhov topology. Yuav kom paub qhov txawv ntawm tus kheej thiab kev tsim nyog ntawm txhua tus neeg siv khoom, txhua tus neeg siv yuav tsum tau sau npe tus account thiab lo lus zais hauv tus neeg teb xov tooj, thiab tom qab ntawd nkag mus rau tus account thiab lo lus zais ntawm nws lub computer siv cov software tshwj xeeb xa mus rau tus neeg teb xov tooj server. Yog tias tus as khauj raug cai, nws tuaj yeem nkag mus rau hauv Internet ib txwm. Tau kawg, qee zaum peb yuav pom tias peb tuaj yeem nkag mus hauv Is Taws Nem yam tsis tau nkag mus rau tus lej password hauv computer. Tias yog vim li cas tus account password yog preset ntawm tus miv, yog li peb tsis tas yuav nkag mus rau nws manually.
Cov saum toj no yog cov lus piav qhia luv luv ntawm broadband thiab dial-up coj los ntawm Shenzhen HDV Phoelectron Technology Co., LTD. Cov khoom siv sib txuas ntawm Shenzhen HDV Phoelectron Technology Co., Ltd. muaj software sib xws nrog peb cov khoom, cov khoom siv network no yogONUseries, kho qhov muag module series,OLTseries, transceiver series.
