Tonse tikudziwa kuti pa LAN yomweyo, kulumikizana kwa hub kumapanga malo otsutsana. Pamene pansi pakusintha, malo otsutsana amatha kuthetsedwa, padzakhala malo owulutsa. Kuti tithane ndi dera lowulutsali, ndikofunikira kuyambitsa ma routers kuti agawane ma LAN osiyanasiyana m'malo osiyanasiyana owulutsa kuti achepetse kusokoneza kwa domain pakati pazida. Kodi tinganene kutikusinthaalinso ndi ntchito ya izirauta? Pambuyo pa chitukuko, lingaliro la VLAN likuperekedwa. VLAN ndi chiyani?
"VLAN" amatanthauza "Virtual Local Area Network."
Network local area network (VLAN) imagawidwa momveka kukhala madera angapo owulutsa, ndipo dera lililonse lowulutsa ndi VLAN. Momwe mungagawire.
Chithunzi chotsatira chikuwonetsakusinthaimagawidwa kukhala ma LAN pafupifupi. Kumanzere, kudzera muzokonda zamkati, izikusinthaimagawaniza dera lowulutsa m'magawo atatu owulutsa, VLAN1, VLAN2, ndi VLAN3. Mwakuthupi, zida izi zili pa chimodzikusintha, koma zomveka, iwo agawidwa mu masinthidwe atatu, kotero padzakhala ma LAN atatu (ma LAN enieni) ndi madera atatu owulutsa.
Kugawa kumasintha kukhala ma LAN enieni
Gawo la VLANkusinthaimasonyeza kuti VLAN 1, nambala ya VLAN, nthawi zambiri imagwira ntchito mu gulu loyang'anira, kotero ma VLAN wamba amawerengedwa kuyambira 2 mpaka 3. Mwachisawawa, ma VLAN onse ndi a VALN1.
Zomwe zili pamwambazi ndizofotokozera za VLAN, kapena LAN yeniyeni, yobweretsedwa ndi Shenzhen Haidiwei Optoelectronics Technology Co., Ltd. Shenzhen HDV Phoelectron Technology Co., Ltd.
