Umuyoboro wibanze waho (VLAN) nubuhanga bwitumanaho bugabanya LAN yumubiri mubice byinshi byogutangaza byumvikana.
?
Buri VLAN ni indangarubuga. Abashitsi muri VLAN barashobora kuvugana muburyo butaziguye, ariko ntibashobora kuvugana nabo. Muri ubu buryo, ibipapuro byo gutangaza bigarukira kuri VLAN imwe ..

Ethernet yambere ni tekinoroji yo gutumanaho amakuru yamakuru ashingiye kuri CSMA / CD (Carrier Sense Multiple Access / Collision Detection) gusangira itangazamakuru ryitumanaho. Umubare munini wabakiriye urashobora guteza amakimbirane akomeye, gutangaza imyuzure, kwangirika kwimikorere, ndetse numuyoboro utaboneka. Nubwo ibikoresho bya Layeri 2 bishobora gukemura amakimbirane akomeye, ntibishobora gutandukanya ibipapuro byamamaza no kuzamura ireme ryurusobe.

Muri iki kibazo, tekinoroji ya VLAN iragaragara. Muri tekinoroji, LAN irashobora kugabanywamo ibice byinshi byumvikana. Buri VLAN ni indangarubuga. Itumanaho hagati yabakiriye muri VLAN ni kimwe no muri LAN. Nkuko bigaragara ku ishusho ikurikira ..
Kubwibyo, vlans ifite ibyiza bikurikira:
Domain Imiyoboro yagabanijwe yo gukwirakwiza: Indangarubuga yo gutangaza igarukira kuri VLAN imwe, ibika umurongo mugari kandi igatezimbere ubushobozi bwo gutunganya imiyoboro.
Yongera umutekano wa LAN. Amapaki muri vlans atandukanye yitandukanije. Nukuvuga, abakoresha muri VLAN imwe ntibashobora kuvugana nabakoresha mubindi vlans.
Gutezimbere imiyoboro ikomeye: amakosa agarukira kuri VLAN imwe gusa. Amakosa muri iyi VLAN ntabwo agira ingaruka kumikorere isanzwe yizindi vlans.
Construction Kubaka byoroshye byimikorere yibikorwa: vlans irashobora gukoreshwa muguha abakoresha batandukanye mumatsinda atandukanye. Abakoresha mumurwi umwe wakazi ntibagarukira kumurongo uhamye wumubiri, bigatuma kubaka urusobe no kubungabunga byoroshye.
Ikoranabuhanga rya Vlan rikoreshwa cyane murihindura, ONU, OLTnibindi bikoresho byitumanaho.
Ibyavuzwe haruguru ni Shenzhen HDV Phoelectron Technology Ltd izana abakiriya kubyerekeye ingingo yo gutangiza VLAN, kandi isosiyete yacu ni umusaruro wihariye wabakora imiyoboro ya optique, ibicuruzwa birimoONUurukurikirane (OLT ONU/ ACONU/ CATVONU/ GPONONU/ XPONONU), Optical module series (optique fibre module / Ethernet optique fibre module / SFP optique module),OLTurukurikirane (OLTibikoresho /OLT hindura/ injangweOLT), nibindi, haribisobanuro bitandukanye byibicuruzwa byitumanaho kubikenewe muburyo butandukanye bwo gushyigikira imiyoboro, ikaze kugisha inama.
