Kwigunga ni iki:
Ibyo bita "kwigunga kumubiri" bivuze ko nta guhuza amakuru hagati yimiyoboro ibiri cyangwa myinshi, kandi ntaho uhurira kumurongo wumubiri / guhuza amakuru / urwego rwa IP.Intego yo kwigunga kumubiri nugukingira ibyuma nibikoresho byitumanaho bya buri rezo ibiza byibasiye inyokomuntu, sabotage yakozwe n'abantu hamwe nibitero bya terefone.Kurugero, kwigunga kumubiri wimbere hamwe numuyoboro rusange birashobora rwose kwemeza ko imiyoboro yamakuru yimbere idaterwa naba hackers kuva kuri enterineti.

Kwigunga kwumvikana ni iki:
Ubwigunge bwumvikana nabwo ni ikintu cyo kwigunga hagati y'imiyoboro itandukanye.Haracyariho umuyoboro wamakuru uhuza kumurongo wumubiri / guhuza amakuru kumurongo wiherereye, ariko uburyo bwa tekiniki burakoreshwa kugirango harebwe ko nta miyoboro yamakuru yatanzwe kumpera yihariye, ni ukuvuga, byumvikana.Kwigunga, gutandukanya byumvikana imiyoboro ya optique ya transcevers / guhinduranya ku isoko muri rusange bigerwaho no kugabanya amatsinda ya VLAN (IEEE802.1Q);

VLAN ihwanye na domaine yo gutangaza igice cya kabiri (data ihuza layer) ya moderi ya OSI yerekana, ishobora kugenzura umuyaga mwinshi muri VLAN.Nyuma yo kugabana VLAN, kubera igabanywa ryogutangaza amakuru, gutandukanya ibyambu bibiri bitandukanye bya VLAN bihuza imiyoboro.

Ibyiza byo kwigunga kumubiri hejuru yo kwigunga:
1. Buri rusobe numuyoboro wigenga, ntiruhindura undi, kandi ntirukorana namakuru;
2. Buri rusobe numuyoboro wigenga wigenga, ubwinshi bwumurongo winjira, ubwinshi bwumurongo uri mumurongo wohereza;
