Shabakadda Aagga Maxalli ah ee Virtual (VLAN) waa tignoolajiyada isgaarsiineed ee u qaybisa LAN-ga jirka qaybo badan oo baahinta si macquul ah.
?
VLAN kasta waa goob warbaahineed. Martigeliyayaasha gudaha VLAN si toos ah ayay isula xidhiidhi karaan, laakiin si toos ah isuma xidhiidhi karaan. Sidan, xirmooyinka baahinta waxay ku xaddidan yihiin hal VLAN.

Early Ethernet waa tignoolajiyada isgaarsiinta xogta ee ku saleysan CSMA/CD Tiro badan oo martigeliyayaal ah ayaa sababi kara isku dhacyo halis ah, daad baahinta, hoos u dhaca waxqabadka, iyo xitaa la'aanta shabakada In kasta oo aaladaha lakabka 2 ay xallin karaan isku dhacyada halista ah, ma go'doomin karaan xirmooyinka baahinta mana hagaajin karaan tayada shabakadda.

Xaaladdan oo kale, tignoolajiyada VLAN ayaa u muuqata. Farsamadan, LAN waxa loo qaybin karaa vlans badan oo macquul ah. VLAN kasta waa goob warbaahineed. Xidhiidhka ka dhexeeya martigeliyaha ku jira VLAN waa la mid kan LAN. Sida ka muuqata sawirka soo socda..
Sidaa darteed, vlans waxay leeyihiin faa'iidooyinka soo socda:
● Qaybta baahinta ee xaddidan: Qaybta baahinta waxa ay ku xaddidan tahay hal VLAN, kaas oo badbaadiya xadhkaha xadhkaha goosha oo wanaajiya awoodda habaynta shabakada.
● Waxay xoojisaa amniga LAN. Baakadaha vlan ee kala duwan ayaa midba midka kale ka go'doonsan yahay. Taasi waa, isticmaalayaasha hal VLAN si toos ah ulama xiriiri karaan isticmaalayaasha vlans kale.
● Waxay wanaajisaa adkeysiga shabakada: khaladaadka waxay ku xaddidan yihiin hal VLAN oo keliya. Cilladaha VLAN-kan ma saameeyaan shaqada caadiga ah ee vlans kale.
● Dhisme dabacsanaan ah oo kooxo shaqo ah: vlans waxa loo isticmaali karaa in lagu meeleeyo isticmaaleyaal kala duwan kooxo shaqo oo kala duwan. Isticmaalayaasha isla kooxda shaqada kuma koobna kala duwanaansho jireed oo go'an, taas oo ka dhigaysa dhismaha shabakada iyo dayactirka mid dabacsan.
Tiknoolajiyada Vlan ayaa si weyn loogu isticmaalaa gudahabeddelo, ONU, OLTiyo isgaarsiinta qalabka kale.
