Kuti utarise traffic yenetwork, senge ongororo yemaitiro evashandisi online, kutarisa traffic zvisina kujairika, uye kutarisa maapplication enetwork, unofanirwa kuunganidza traffic yenetwork. Kubata traffic yenetwork kungave kusina kururama. Kutaura zvazviri, unofanirwa kukopa traffic yenetwork iripo woitumira kune monitoring device. Network splitter, inozivikanwawo seNetwork TAP. Inongoshanda basa iri. Ngatitarisei tsananguro yeNetwork TAP:
I. Network Tap mudziyo wehardware unopa nzira yekuwana data rinoyerera kuburikidza nenetwork yekombuta. (kubva kuWikipedia)
II. ATap yeNetiweki, inozivikanwawo seTest Access Port, mudziyo wehardware unobatanidzirwa zvakananga muNetwork cable uye unotumira chikamu cheNetwork communication kune mamwe ma devices. Network splitters dzinowanzo shandiswa muma network intrusion detection systems (IPS), network detectors, uye profilers. Kudzokorora kutaurirana kune network devices ikozvino kunowanzoitwa kuburikidza ne switching port analyzer (span port), inozivikanwawo se port mirroring mu network switching.
III. Network Taps inoshandiswa kugadzira ma "access ports" ekugara kwenguva refu ekutarisa pasina kupindira. "Tap", kana kuti "Test Access Port", inogona kuiswa pakati pemidziyo miviri yenetwork, yakaita se "switches", "routers" uye "firewalls". Inogona kushanda se "access port" ye "monitoring device" inoshandiswa kuunganidza data riri mu "line", kusanganisira "Intrusion detection system", "Intrusion prevention system" inoshandiswa mu "passive mode", "protocol analyzers" uye "remote monitoring tools". (kubva kuNetOptics).
Kubva pane tsanangudzo nhatu dziri pamusoro apa, tinogona kudhirowa hunhu hwakasiyana hweNetwork TAP: hardware, inline, transparent
Heino tarisiro yezvinhu izvi:
1. I hardware yakazvimiririra, uye nekuda kweizvi, haina kana kukanganisa mutoro wezvishandiso zve network zviripo, izvo zvine mabhenefiti makuru pane ma port mirroring
2. Chishandiso chiri mu-line. Zvichitaurwa zviri nyore, chinofanira kubatanidzwa kune network, izvo zvinogona kunzwisiswa. Zvisinei, izvi zvinewo kuipa kwekuisa poindi yekukundikana, uye nekuti chishandiso chiri online, network iripo inofanira kukanganiswa panguva yekuiswa, zvichienderana nekuti yaiswa kupi.
3. Transparent zvinoreva pointer kune network iripo. Access networks mushure me shunt, network iripo yemidziyo yese, haina zvayakaita, kwavari yakajeka chose, hongu, inewo network shunt tumira traffic kumodhi yemidziyo, modhi ye monitoring yenetwork yakajeka, zvinoita sekunge uri mu new access to new electrical outlet, kune mimwe midziyo iripo, Hapana chinoitika, kusanganisira paunozobvisa mudziyo wacho wobva wangoyeuka nhetembo inoti, "Wave sleeve yako kwete gore"......
Vanhu vazhinji vanoziva nezve port mirroring. Ehe, port mirroring inogonawo kuita zvakafanana. Heino kuenzanisa pakati peNetwork Taps/Diverters nePort Mirroring:
1. Sezvo chiteshi cheswitch pachayo chichizosefa mamwe mapaketi ezvikanganiso nemapaketi ane saizi diki kwazvo, kuiisa pamichina hakugone kuvimbisa kuti traffic yese inogona kuwanikwa. Zvisinei, shunter inovimbisa kuvimbika kwedata nekuti "yakakopwa" zvizere pachikamu chemuviri.
2. Panyaya yekushanda kwenguva chaiyo, pane mamwe maswichi emhando yepasi, kurongedza magirazi echiteshi kunogona kukonzera kunonoka kana kuchikopa traffic kuenda kumagirazi echiteshi, uye zvakare kunokonzera kunonoka kana kuchikopa mahwindo e10/100m kuenda kumaGIGA ports
3. Kutarisa magirazi echiteshi kunoda kuti bandwidth yechiteshi chine girazi ive yakakura kupfuura kana kuti yakaenzana nehuwandu hwema bandwidth ema mirrored ports ese. Zvisinei, chinodiwa ichi chingasazadzikiswa nema switch ese
4. Kutarisa magirazi echiteshi kunofanirwa kugadziriswa paswitch. Kana nzvimbo dzinofanira kutariswa dzave kuda kugadziriswa, switch yacho inofanira kugadziriswazve.
