Inethiwekhi yendawo yengingqi (VLAN) iteknoloji yonxibelelwano eyahlula i-LAN ebonakalayo kwiindawo ezininzi zokusasaza ngengqiqo.
I-VLAN nganye yindawo yosasazo. Iinginginya ezingaphakathi kweVLAN zinokunxibelelana ngokuthe ngqo omnye nomnye, kodwa azikwazi ukunxibelelana ngokuthe ngqo. Ngale ndlela, iipakethi zokusasaza zithintelwe kwiVLAN enye.
I-Early Ethernet iteknoloji yonxibelelwano lwenethiwekhi yedatha esekelwe kwi-CSMA / CD (i-Carrier Sense Access Multiple / Conlision Detection) ukwabelana ngeendaba zonxibelelwano. Inani elikhulu leenginginya zingabangela ungquzulwano olumandundu, izikhukhula zosasazo, ukuthotywa komgangatho wokusebenza, kunye nokungafumaneki kothungelwano. Nangona izixhobo zeLayer 2 zinokucombulula iingxabano ezinzulu, azikwazi ukwahlula iipakethi zokusasaza kunye nokuphucula umgangatho womnatha.
Kule meko, iteknoloji yeVLAN ibonakala. Kule teknoloji, i-LAN inokwahlulwa ibe yi-vlans ezininzi ezinengqiqo. I-VLAN nganye yindawo yosasazo. Unxibelelwano phakathi kwenginginya kwi-VLAN iyafana naleyo ikwi-LAN. Njengoko kubonisiwe kumfanekiso olandelayo..
Ke ngoko, ii-vlans zineenzuzo ezilandelayo:
● I-domain yosasazo ethintelweyo: I-domain yosasazo ikhawulelwe kwi-VLAN enye, egcina i-bandwidth kunye nokuphucula amandla okusebenza kwenethiwekhi.
● Ukwandisa ukhuseleko lwe-LAN. Iipakethi kwii-vlans ezahlukeneyo zodwa omnye komnye. Oko kukuthi, abasebenzisi kwi-VLAN enye abakwazi ukunxibelelana ngokuthe ngqo nabasebenzisi kwezinye iivlan.
● Ukuphucula ukomelela kwenethiwekhi: iimpazamo zithintelwe kuphela kwiVLAN enye. Iimpazamo kule VLAN azichaphazeli ukusebenza okuqhelekileyo kwezinye ii-vlans.
● Ukwakhiwa okuguquguqukayo kwamaqela okusebenza okubonakalayo: ii-vlans zingasetyenziselwa ukwabela abasebenzisi abahlukeneyo kumaqela okusebenza ahlukeneyo. Abasebenzisi kwiqela lomsebenzi elifanayo abakhawulelwanga kuluhlu olusisigxina lomzimba, okwenza ukwakhiwa kwenethiwekhi kunye nokugcinwa kuguquguquke ngakumbi.
Itekhnoloji yeVlan isetyenziswa ngokubanzi kwitshintsha, I-ONU, OLTkunye nolunye unxibelelwano lwesixhobo.
Oku ngasentla yi-Shenzhen HDV Phoelectron Technology Ltd. izisa abathengi malunga nenqaku lentshayelelo ye-VLAN, kwaye inkampani yethu iyimveliso ekhethekileyo yabavelisi benethiwekhi yamehlo, iimveliso ezibandakanyekayo.I-ONUuthotho (OLT I-ONU/ACI-ONU/CATVI-ONU/GPONI-ONU/XPONI-ONU), uchungechunge lwemodyuli ye-Optical (imodyuli yefiber optical / Ethernet imodyuli yefiber optical / SFP imodyuli yokubona),OLTuthotho (OLTizixhobo /OLT tshintsha/ikati yamehloOLT), njl., kukho iinkcukacha ezahlukeneyo zeemveliso zonxibelelwano kwiimfuno zeemeko ezahlukeneyo zenkxaso yenethiwekhi, wamkelekile ukubonisana.
