A virtual local Area Network (VLAN) inyanzvi yekutaurirana iyo inokamura LAN yemuviri mumatunhu akawanda enhepfenyuro zvine musoro.
.
Imwe neimwe VLAN inzvimbo yekutepfenyura. Mauto ari mukati meVLAN anogona kutaurirana zvakanangana, asi haakwanise kutaurirana zvakananga kune mumwe nemumwe. Nenzira iyi, mapaketi ekutepfenyura anongogumira kune imwe VLAN.

Early Ethernet tekinoroji yedata network yekutaurirana yakavakirwa paCSMA/CD (Carrier Sense Multiple Access/Collision Detection) inogovera midhiya yekutaurirana. Huwandu hukuru hwevaenzi hunogona kukonzera kukakavara kwakakomba, mafashama enhepfenyuro, kuderedzwa kwemaitiro, uye kunyange kusawanikwa kwetiweki. Kunyangwe Layer 2 michina inogona kugadzirisa kukakavara kwakakomba, haigone kuparadzanisa mapaketi enhepfenyuro uye kugadzirisa network kunaka.

Muchiitiko ichi, teknolojia yeVLAN inooneka. Mune tekinoroji iyi, LAN inogona kukamurwa kuita akawanda anonzwisisika vlans. Imwe neimwe VLAN inzvimbo yekutepfenyura. Kukurukurirana pakati pevaenzi muVLAN kwakafanana neicho muLAN. Sezvinoratidzwa pamufananidzo unotevera..
Naizvozvo, vlans vane zvinotevera zvakanakira:
● Inodzvinyirirwa dhiyabhorosi: Nzvimbo yekutepfenyura inongogumira kune imwe VLAN, iyo inochengetedza bandwidth uye inovandudza network kugadzirisa kugona.
● Inovandudza LAN kuchengetedza. Mapaketi mune akasiyana vlans akaparadzaniswa kubva kune mumwe. Ndiko kuti, vashandisi mune imwe VLAN havagone kutaurirana zvakananga nevashandisi mune mamwe mavlans.
● Inovandudza kusimba kwetiweki: kukanganisa kunongowanikwa kune imwe chete VLAN. Mhosho muVLAN iyi haikanganisi kushanda kwakajairwa kwemamwe mavlans.
● Flexible kuvaka kwe virtual workgroups: vlans inogona kushandiswa kupa vashandisi vakasiyana kumapoka ekushanda akasiyana. Vashandisi vari muboka rimwe chete rebasa havana kuganhurirwa kune yakatemwa yemuviri siyana, izvo zvinoita kuti network kuvaka uye kugadzirisa kuchinjika.
Vlan tekinoroji inoshandiswa zvakanyanya mukatichinja, ONU, OLTuye kumwe kutaurirana kwemudziyo.
Iri pamusoro iShenzhen HDV Phoelectron Technology Ltd inounza vatengi nezvechinyorwa cheVLAN chekusuma, uye kambani yedu inyanzvi yekugadzira yevanogadzira network vanogadzira, zvigadzirwa zvinosanganisirwa.ONUseries (OLT ONU/ACONU/CATVONU/GPONONU/XPONONU), Optical module series (optical fiber module/Ethernet optical fiber module/SFP optical module),OLTseries (OLTmidziyo /OLT chinja/katsi yemazisoOLT), nezvimwewo, kune zvakasiyana-siyana zvinotsanangurwa zvekutaurirana zvigadzirwa zvezvido zvemamiriro akasiyana ekutsigira network, kugamuchirwa kubvunza.
