Nplhaib qaum
NPAJ NTAUB NTAWV yog ib tsob ntoo SPANNING lub qaum qaum nyob hauv cheeb tsam nroog. Cov qauv no tuaj yeem raug deformed rau hauv lub network qauv, uas yog tsim rau cov high-density central koog tsev kawm ntawv nyob rau hauv lub nroog cheeb tsam network thiab tsim ib tug txhaum rau cov tub ntxhais qaum network. Kev txhawb nqa rau IEEE.1q thiab ISL network nta tuaj yeem ua kom muaj kev sib raug zoo nrog feem ntau lub hauv paus caj qaum tes hauj lwm, xws li hla hloov VLAN, TRUNK thiab lwm yam haujlwm. Nplhaib qaum network tuaj yeem tsim broadband virtual private network rau nyiaj txiag, tsoomfwv, kev kawm thiab lwm yam lag luam.
Chain backbone network
Cov sawrov qab networktuaj yeem txuag tau ntau lub teeb nraub qaum los ntawm kev siv cov saw txuas. Nws yog qhov tsim nyog rau kev tsim cov pob txha caj qaum nrog lub siab bandwidth thiab tus nqi qis nyob rau hauv periphery ntawm lub nroog thiab sub-county. Cov qauv no tseem tuaj yeem siv rau hauv ib puag ncig ntawm kev nthuav dav, cov roj xa hluav taws xob thiab cov kab sib txuas. Cov saw caj npab txhawb nqa IEEE802.1Q thiab ISL network nta, uas tuaj yeem ua kom muaj kev sib raug zoo nrog feem ntau ntawm cov pob txha caj qaum, thiab tuaj yeem teeb tsa broadband virtual private networks rau nyiaj txiag, tsoomfwv, kev kawm thiab lwm yam lag luam. Chain backbone network yog multimedia network uas tuaj yeem muab kev sib txuas ntawm cov duab, suab, cov ntaub ntawv thiab saib xyuas lub sijhawm.
Cov neeg siv khoom nkag system
Tus neeg siv nkag tau siv 10Mbps / 100Mbps adaptive thiab 10Mbps / 100Mbps tsis siv neeg hloov dua siab tshiab ua haujlwm los txuas rau txhua tus neeg siv khoom, tsis tas yuav npaj ntau lub fiber ntau optic transceivers, uas tuaj yeem muab tau yooj yim.network upgrade tswvyim. Tib lub sijhawm, ib nrab-duplex / full-duplex adaptive thiab ib nrab-duplex / full-duplex tsis siv neeg hloov dua siab tshiab tuaj yeem siv los teeb tsa pheej yig ib nrab-duplex HUB ntawm tus neeg siv khoom kawg, uas tuaj yeem txo cov nqi sib txuas ntawm tus neeg siv khoom kawg. kaum ob lub sij hawm thiab txhim kho kev sib tw ntawm cov tswv lag luam network.
