Kuyini ukuzihlukanisa ngokomzimba:
Lokhu okubizwa ngokuthi “ukuhlukaniswa ngokomzimba” kusho ukuthi akukho ukuxhumana kwedatha phakathi kwamanethiwekhi amabili noma ngaphezulu, futhi akukho ukuxhumana kungqimba olubonakalayo/ungqimba lwesixhumanisi sedatha/sendlalelo se-IP.Inhloso yokuhlukaniswa ngokomzimba ukuvikela izinhlangano zehadiwe nezixhumanisi zokuxhumana zenethiwekhi ngayinye ezinhlekeleleni zemvelo, ukucekelwa phansi kwabantu kanye nokuhlaselwa kwe-wiretapping.Isibonelo, ukuhlukaniswa ngokomzimba kwenethiwekhi yangaphakathi kanye nenethiwekhi yomphakathi kungaqinisekisa ngempela ukuthi inethiwekhi yolwazi lwangaphakathi ayihlaselwa izigebengu ze-inthanethi.

Kuyini ukuzihlukanisa okunengqondo:
I-isolator enengqondo iphinde ibe ingxenye yokuhlukanisa phakathi kwamanethiwekhi ahlukene.Kusenokuxhumana kweshaneli yedatha kungqimba olubonakalayo/isixhumanisi sedatha ungqimba emaphethelweni angawodwa, kodwa izindlela zobuchwepheshe zisetshenziswa ukuze kuqinisekiswe ukuthi awekho amashaneli edatha ezindaweni ezingazodwa, okungukuthi, ngokunengqondo.Ukuzihlukanisa, ukuhlukaniswa okunengqondo kwama-transceivers optical network emakethe ngokuvamile kufezwa ngokuhlukanisa amaqembu e-VLAN (IEEE802.1Q);

I-VLAN ilingana nesizinda sokusakaza sesendlalelo sesibili (usendlalelo sesixhumanisi sedatha) semodeli yereferensi ye-OSI, engalawula isiphepho sokusakaza ngaphakathi kwe-VLAN.Ngemva kokuhlukanisa i-VLAN, ngenxa yokwehliswa kwesizinda sokusakaza, ukuhlukaniswa kwezimbobo zenethiwekhi yeqembu le-VLAN ehlukene kuyabonakala.

Izinzuzo zokuzihlukanisa ngokomzimba ngaphezu kokuzihlukanisa okunengqondo:
1. Inethiwekhi ngayinye iyishaneli ezimele, ayinalo ithonya komunye nomunye, futhi ayihlangani nedatha;
2. Inethiwekhi ngayinye iwumkhawulokudonsa ozimele wesiteshi, ungakanani umkhawulokudonsa ongena, ungakanani umkhawulokudonsa esiteshini sokudlulisa;
