Ukuze uqaphe ithrafikhi yenethiwekhi, njengokuhlaziywa kokuziphatha komsebenzisi ku-inthanethi, ukuqapha ithrafikhi okungavamile, kanye nokuqapha uhlelo lokusebenza lwenethiwekhi, udinga ukuqoqa ithrafikhi yenethiwekhi. Ukuthwebula ithrafikhi yenethiwekhi kungase kungabi nembile. Eqinisweni, udinga ukukopisha ithrafikhi yenethiwekhi yamanje bese uyithumela kudivayisi yokuqapha. I-Network splitter, eyaziwa nangokuthi i-Network TAP. Imane yenza lo msebenzi. Ake sibheke incazelo ye-Network TAP:
I. I-Network Tap iyidivayisi yehadiwe enikeza indlela yokufinyelela idatha egeleza kunethiwekhi yekhompyutha. (kusukela ku-wikipedia)
II. AUkuthepha Kwenethiwekhi, eyaziwa nangokuthi i-Test Access Port, iyidivayisi yehadiwe exhuma ngqo kukhebula leNethiwekhi bese ithumela ingxenye yokuxhumana kweNethiwekhi kwamanye amadivayisi. Ama-splitter enethiwekhi avame ukusetshenziswa ezinhlelweni zokuthola ukungena kwenethiwekhi (i-IPS), ama-detector enethiwekhi, kanye namaphrofayili. Ukukopisha ukuxhumana kumadivayisi enethiwekhi manje kwenziwa nge-switching port analyzer (span port), eyaziwa nangokuthi i-port mirroring ekushintsheni kwenethiwekhi.
III. Ama-Network Taps asetshenziselwa ukudala ama-port okufinyelela unomphela ukuze kuqashwe ngokunganaki. I-tap, noma i-Test Access Port, ingasethwa phakathi kwamadivayisi amabili enethiwekhi, njenge-switch, ama-router kanye nama-firewall. Ingasebenza njenge-port yokufinyelela yedivayisi yokuqapha esetshenziselwa ukuqoqa idatha esemgqeni, kufaka phakathi uhlelo lokuthola ukungena, uhlelo lokuvimbela ukungena olusetshenziswa kwimodi enganaki, abahlaziyi bephrothokholi kanye namathuluzi okuqapha akude. (kusuka ku-NetOptics).
Kusukela ezincazelweni ezintathu ezingenhla, singakwazi ukudweba izici eziningana ze-Network TAP: ihadiwe, i-inline, i-transparent
Nasi ukubuka lezi zici:
1. Kuyi-hardware ezimele, futhi ngenxa yalokhu, ayinawo umthelela emthwalweni wamadivayisi enethiwekhi akhona, anezinzuzo ezinkulu kunezibuko ze-port
2. Iyidivayisi esemgqeni. Kalula nje, idinga ukuxhunywa kunethiwekhi, okungaqondwa. Kodwa-ke, lokhu futhi kunephutha lokwethula iphuzu lokwehluleka, futhi ngenxa yokuthi iyidivayisi eku-inthanethi, inethiwekhi yamanje idinga ukuphazanyiswa ngesikhathi sokufakwa, kuye ngokuthi isetshenziswa kuphi.
3. Ukucaca kubhekisela enkombeni yenethiwekhi yamanje. Amanethiwekhi okufinyelela ngemva kwe-shunt, inethiwekhi yamanje yayo yonke imishini, ayinawo umphumela, kubo isobala ngokuphelele, vele, iqukethe ne-shunt yenethiwekhi ukuthumela ithrafikhi ukuqapha imishini, idivayisi yokuqapha yenethiwekhi isobala, kunjengokungathi usekufinyeleleni okusha endaweni entsha kagesi, kwezinye izinto ezikhona, Akukho okwenzekayo, okuhlanganisa nalapho ekugcineni ususa ithuluzi bese ukhumbula ngokuzumayo inkondlo ethi, "Wave your sleeve hhayi ifu"......
Abantu abaningi bajwayelene nokulingisa izibuko. Yebo, ukulingisa izibuko nakho kungafeza umphumela ofanayo. Nasi ukuqhathanisa phakathi kwe-Network Taps/Diverters kanye ne-Port Mirroring:
1. Njengoba imbobo yeswishi ngokwayo izohlunga amanye amaphakethe amaphutha namaphakethe anosayizi omncane kakhulu, ukwenza izibuko ngembobo akuqinisekisi ukuthi yonke ithrafikhi ingatholakala. Kodwa-ke, i-shunter iqinisekisa ubuqotho bedatha ngoba "ikopishwe" ngokuphelele kungqimba olubonakalayo.
2. Ngokuphathelene nokusebenza kwesikhathi sangempela, kwezinye izinkinobho ezisezingeni eliphansi, ukulingisa izibuko kungase kubangele ukubambezeleka lapho kukopisha ithrafikhi kuma-port abonisa izibuko, futhi kuphinde kwethule ukubambezeleka lapho kukopisha ama-port angu-10/100m kuma-port e-GIGA
3. Ukulinganisa imbobo kudinga ukuthi ububanzi bembobo ebonisiwe bube bukhulu noma bulingane nesamba semingcele yazo zonke izimbobo ezibonisiwe. Kodwa-ke, lesi sidingo singase singahlangatshezwa yizo zonke izishintshi
4. Ukulinganisa imbobo kudinga ukulungiswa kuswishi. Uma izindawo ezizoqashwa zidinga ukulungiswa, iswishi idinga ukulungiswa kabusha.
