Kugirango dusesengure urujya n'uruza, birakenewe kohereza paki y'urusobekerane kuri NTOP / NPROBE cyangwa hanze yumurongo wumutekano hamwe nogukurikirana. Hariho ibisubizo bibiri kuri iki kibazo:
Indorerwamo(bizwi kandi nka SPAN)
Kanda Umuyoboro.
Mbere yo gusobanura itandukaniro riri hagati y ibisubizo byombi (Port Mirror na Network Tap), ni ngombwa kumva uburyo Ethernet ikora. Kuri 100Mbit no hejuru, abashyitsi mubisanzwe bavuga muri duplex yuzuye, bivuze ko uwakiriye ashobora kohereza (Tx) akakira (Rx) icyarimwe. Ibi bivuze ko kuri kabili 100 Mbit ihujwe numucumbitsi umwe, igiteranyo cyurugendo rwurusobe umuyoboro umwe ashobora kohereza / kwakira (Tx / Rx)) ni 2 × 100 Mbit = 200 Mbit.
Indorerwamo ya Port nigikorwa cyo kwigana paki, bivuze ko igikoresho cyurusobe gifite inshingano zo gukoporora paki kuricyambu.
Ibi bivuze ko igikoresho kigomba gukora iki gikorwa ukoresheje ibikoresho bimwe na bimwe (nka CPU), kandi ibyerekezo byombi byumuhanda bizigana ku cyambu kimwe. Nkuko byavuzwe haruguru, muri A duplex yuzuye, ibi bivuze ko
A -> B na B -> A.
Igiteranyo cya A ntikizarenza umuvuduko wurusobe mbere yuko gutakaza paki bibaho. Ibi ni ukubera ko nta mwanya uhari wo kwigana paki. Biragaragara ko indorerwamo yicyambu ari tekinike ikomeye kuko ishobora gukorwa na swike nyinshi (ariko sibyose), kuberako ibyinshi byahinduwe hamwe nibibi byo gutakaza paki, niba ukurikirana umurongo ufite imitwaro irenga 50%, cyangwa indorerwamo ibyambu ku cyambu cyihuse (urugero indorerwamo 100 Mbit ibyambu kuri 1 Gbit). Tutibagiwe ko indorerwamo zipakurura zishobora gusaba guhana ibikoresho, bishobora gutwara igikoresho kandi bigatera imikorere yo guhana agaciro. Menya ko ushobora guhuza icyambu 1 ku cyambu kimwe, cyangwa 1 VLAN ku cyambu kimwe, ariko muri rusange ntushobora kwigana ibyambu byinshi kuri 1. (Nkuko rero indorerwamo yapaki) yabuze.
Umuyoboro TAP (Terminal Access Point)ni igikoresho cyuzuye cyuma cyuma, gishobora gufata traffic kuri neti. Bikunze gukoreshwa mugukurikirana traffic hagati yingingo ebyiri murusobe. Niba umuyoboro uri hagati yizi ngingo zombi ugizwe numuyoboro wumubiri, umuyoboro TAP urashobora kuba inzira nziza yo gufata traffic.
Umuyoboro TAP ufite byibura ibyambu bitatu: icyambu, icyambu B, nicyambu. Gushyira igikanda hagati yingingo A na B, umuyoboro wumuyoboro uri hagati ya A na point B usimbuzwa insinga ebyiri, imwe ijya ku cyambu cya TAP, indi igana ku cyambu cya TAP. TAP inyura traffic zose hagati yinzira zombi, bityo ziracyahujwe. TAP kandi ikoporora traffic kuri port yayo ikurikirana, bityo igafasha igikoresho cyo gusesengura kumva.
Umuyoboro wa TAP ukoreshwa mugukurikirana no gukusanya ibikoresho nka APS. TAP irashobora kandi gukoreshwa mubisabwa byumutekano kuko idahwitse, ntishobora kugaragara kumurongo, irashobora gukorana na duplex yuzuye kandi idasangiwe, kandi mubisanzwe izanyura mumodoka kabone niyo kanda ihagarika gukora cyangwa gutakaza ingufu. .
Nka Network Taps ibyambu bitakira ariko byohereza gusa, switch nta kimenyetso yicaye inyuma yicyambu. Ingaruka ni uko isakaza paki ku byambu byose. Kubwibyo, niba uhuza igikoresho cyawe cyo kugenzura kuri switch, igikoresho nkicyo kizakira paki zose. Menya ko ubu buryo bukora niba igikoresho cyo kugenzura cyohereje paki iyo ari yo yose; bitabaye ibyo, uhindura azakeka ko paki zafashwe zitagenewe ibikoresho nkibi. Kugirango ubigereho, urashobora gukoresha insinga y'urusobekerane utigeze uhuza insinga za TX, cyangwa ugakoresha interineti itagabanije IP (na DHCP-nkeya) itohereza paki na gato. Hanyuma, menya ko niba ushaka gukoresha igikanda kugirango udatakaza paki, noneho ntugahuze icyerekezo cyangwa ngo ukoreshe icyerekezo aho icyerekezo cyerekanwe kigenda gahoro (urugero 100 Mbit) ko icyambu cyo guhuza (urugero 1 Gbit).
