    Nirtual local area network

    Nthawi yotumiza: Aug-13-2024

    A Virtual Local Area Network (VLAN) ndiukadaulo wolumikizirana womwe umagawa LAN yakuthupi m'magawo angapo owulutsa momveka bwino.
    pa
    VLAN iliyonse ndi malo owulutsa. Okhala mkati mwa VLAN amatha kulumikizana mwachindunji, koma sangathe kulumikizana mwachindunji. Mwanjira iyi, mapaketi owulutsa amangokhala ku VLAN imodzi.
    pa
    Early Ethernet ndi ukadaulo wapaintaneti wa data wozikidwa pa CSMA/CD (Carrier Sense Multiple Access/Collision Detection) yogawana media media. Chiwerengero chochuluka cha olandila atha kuyambitsa mikangano yayikulu, kusefukira kwa mawayilesi, kuwonongeka kwa magwiridwe antchito, ngakhalenso kusapezeka kwa maukonde. Ngakhale zida za Layer 2 zimatha kuthetsa mikangano yayikulu, sizingalekanitse mapaketi owulutsa ndikuwongolera maukonde.
    pa
    Pankhaniyi, ukadaulo wa VLAN ukuwoneka. Muukadaulo uwu, LAN imatha kugawidwa kukhala ma vlans angapo omveka. VLAN iliyonse ndi malo owulutsa. Kulumikizana pakati pa makamu mu VLAN ndikofanana ndi komwe kuli mu LAN. Monga zikuwonekera pachithunzipa..

    Chifukwa chake, ma vlan ali ndi zabwino izi:

    ● Dongosolo lowulutsa loletsedwa: Dongosolo lowulutsa limangokhala pa VLAN imodzi, yomwe imasunga bandwidth ndikuwongolera kuthekera kokonza maukonde.
    ● Imalimbitsa chitetezo cha LAN. Mapaketi amitundu yosiyanasiyana amasiyanitsidwa. Ndiko kuti, ogwiritsa ntchito mu VLAN imodzi sangathe kulankhulana mwachindunji ndi ogwiritsa ntchito ma vlan ena.
    ● Imawonjezera kulimba kwa netiweki: zolakwika zimangopezeka pa VLAN imodzi yokha. Zolakwika mu VLAN iyi sizimakhudza magwiridwe antchito a ma vlans ena.
    ● Kupanga kosinthika kwamagulu ogwira ntchito: ma vlans angagwiritsidwe ntchito kupatsa ogwiritsa ntchito osiyanasiyana kumagulu osiyanasiyana ogwira ntchito. Ogwiritsa ntchito omwe ali mu gulu lomwelo sakhala ndi mawonekedwe okhazikika, zomwe zimapangitsa kuti kumanga ndi kukonza maukonde kukhale kosavuta.

    Tekinoloje ya Vlan imagwiritsidwa ntchito kwambiri mukusintha, ONU, OLTndi kulumikizana kwa zida zina.

    Zomwe zili pamwambazi ndi Shenzhen HDV Phoelectron Technology Ltd. kubweretsa makasitomala za nkhani yoyambilira ya VLAN, ndipo kampani yathu ndi yopanga mwapadera opanga opanga ma netiweki, zomwe zikukhudzidwa.ONUmndandanda (OLT ONU/ACONU/CATVONU/GPONONU/XPONONU), Optical module series (optical fiber module/Ethernet optical fiber module / SFP Optical module),OLTmndandanda (OLTzida /OLT kusintha/ mphaka wowonekaOLT), etc., pali specifications zosiyanasiyana za mankhwala kulankhulana kwa zosowa za zochitika zosiyanasiyana thandizo maukonde, kulandiridwa kufunsira.
