Yintoni ukuzahlula ngokwasemzimbeni:
Okubizwa ngokuba "ukuzihlukanisa ngokomzimba" kuthetha ukuba akukho nxu lumano lwedatha phakathi kwamanethiwekhi amabini okanye ngaphezulu, kwaye akukho mdibaniselwano kwinqanaba lomzimba / ikhonkco yedatha / i-IP layer.Injongo yokwahlukaniswa ngokomzimba kukukhusela amaziko e-hardware kunye namakhonkco onxibelelwano womnatha ngamnye kwiintlekele zendalo, i-sabotage eyenziwe ngabantu kunye nokuhlaselwa kwe-wiretapping.Umzekelo, ukwahlukaniswa ngokomzimba kwenethiwekhi yangaphakathi kunye nenethiwekhi yoluntu inokuqinisekisa ngokwenene ukuba inethiwekhi yolwazi lwangaphakathi ayihlaselwa ngabaduni abavela kwi-Intanethi.

Yintoni ukubekwa wedwa okusengqiqweni:
I-isolator enengqondo ikwalicandelo lokuzahlula phakathi kwenethiwekhi ezahlukeneyo.Kusekho uxhulumaniso lweshaneli yedatha kwinqanaba lomzimba / ikhonkco yedatha kwiiphelo ezizimeleyo, kodwa iindlela zobugcisa zisetyenziselwa ukuqinisekisa ukuba akukho ziteshi zedatha kwiiphelo ezizimeleyo, oko kukuthi, ngokwengqiqo.Ukuzihlukanisa, ukuhlukaniswa okunengqiqo kwe-network optical transceivers / switches kwimarike ngokuqhelekileyo kufezekiswa ngokwahlula amaqela eVLAN (IEEE802.1Q);

I-VLAN ilingana ne-domain yokusasazwa kwinqanaba lesibini (idatha yekhonkco yedatha) yemodeli yereferensi ye-OSI, enokulawula isaqhwithi sosasazo ngaphakathi kweVLAN.Emva kokwahlula i-VLAN, ngenxa yokunciphisa indawo yosasazo, ukwahlukaniswa kwamachweba amabini ahlukeneyo enethiwekhi yeVLAN kuyafezekiswa.

Izinto eziluncedo zokuzihlukanisa ngokwasemzimbeni ngaphezu kokuba wedwa okusengqiqweni:
1. Inethiwekhi nganye yitshaneli ezimeleyo, ayinayo impembelelo komnye nomnye, kwaye ayisebenzisi kunye nedatha;
2. Inethiwekhi nganye yi-bandwidth ye-channel ezimeleyo, ingakanani i-bandwidth engena, ingakanani i-bandwidth kwi-channel yokudlulisa;
