Ukuqapha ithrafikhi yenethiwekhi, njengokuhlaziywa komsebenzisi kokuziphatha kwe-inthanethi, ukuqapha kwethrafikhi okungajwayelekile, nokuqapha uhlelo lwenethiwekhi, udinga ukuqoqa ithrafikhi yenethiwekhi. Ukuthwebula ithrafikhi yenethiwekhi kungenzeka kube okungalungile. Eqinisweni, udinga ukukopisha ithrafikhi yenethiwekhi yamanje bese uyithumela kudivayisi yokuqapha. Isihlukanisi senethiwekhi, esaziwa nangokuthi Thepha Network. Ukwenza nje lo msebenzi. Ake sibheke incazelo yokuthepha kwenethiwekhi:
I. I-Tap yenethiwekhi iyithuluzi le-Hardware elinikeza indlela yokufinyelela idatha egeleza ngaphesheya kwenethiwekhi yekhompyutha. (Kusuka ku-Wikipedia)
II. AThepha ngenethiwekhi, eyaziwa nangokuthi i-Test Excent Port, iyithuluzi le-Hardware elixhuma ngqo kwikhebula lenethiwekhi bese lithumela ucezu lokuxhumana kwenethiwekhi kwamanye amadivayisi. Ama-Splitters wenethiwekhi asetshenziswa kakhulu ezinhlelweni zokutholwa kwe-Network Antring (IPS), abathola amanethiwekhi, kanye nabaphrofethi. Ukuphindaphinda ukuxhumana kumadivayisi wenethiwekhi manje kuvame ukwenziwa ngePort Port Analyzer (Port Port), eyaziwa nangokuthi izibuko zePort ku-Network ekushintsheni kwenethiwekhi.
III. Ompompi wenethiwekhi basetshenziselwa ukudala amachweba wokufinyelela unomphela wokuqapha nje. I-Tap, noma i-Test Port Port, ingasethwa phakathi kwanoma yimaphi amadivaysi enethiwekhi amabili, njengokushintshwa, ama-router kanye nama-firewall. Ingasebenza njengembobo yokufinyelela yokuqapha idivaysi esetshenziselwa ukuqoqa idatha ye-in-line, kufaka phakathi uhlelo lokuthola ulwazi, uhlelo lokuvimbela ukungena ngaphakathi oluthunyelwe kwimodi yokuphambuka, amathuluzi okuhlola okukude. (kusuka ku-NETOPTICS).
Kusuka kulezi zincazelo ezintathu ezingenhla, ngokuyisisekelo singakwazi ukudweba izici eziningana zokuthepha kwenethiwekhi: Hardware, inline, esobala
Nakhu ukubheka lezi zici:
1. Ucezu oluzimele lwe-Hardware, futhi ngenxa yalokhu, alunamthelela emthwalweni wamadivayisi akhona wenethiwekhi, anezinzuzo ezinhle kakhulu zokubukwa kwetheku
2. Kuyinto e-in-line. Kalula nje, idinga ukuxhunywa kwinethiwekhi, engaqondakala. Kodwa-ke, lokhu kubuye kube nokungabi nabikwa kokwethula iphuzu lokuhluleka, futhi ngoba kuyithuluzi eliku-inthanethi, inethiwekhi yamanje idinga ukuphazanyiswa ngesikhathi sokufakwa, kuye ngokuthi kuthunyelwe kuphi.
I-3. I-Transparent ibhekisela kwi-pointer kwinethiwekhi yamanje. Finyelela amanethiwekhi ngemuva kwe-shunt, inethiwekhi yamanje yayo yonke imishini, awunawo umphumela, ngoba uqukethe i-Network Shunt ukuthumela ithrafikhi, kufana nokususa inkondlo,
Abantu abaningi bajwayelene nokubukwa kwetheku. Yebo, izibuko ze-port zingafinyelela nomphumela ofanayo. Nakhu ukuqhathanisa phakathi ompompi / ama-diverters kanye ne-portroring portring:
1. Njengoba itheku le-switch ngokwalo lizohlunga amanye amaphakethe amaphutha namaphakethe ngosayizi omncane kakhulu, izibuko zetheku azikwazi ukuqiniseka ukuthi yonke ithrafikhi ingatholakala. Kodwa-ke, i-shunter iqinisekisa ubuqotho bemininingwane ngoba "ikopishwa" ngokuphelele kungqimba ngokomzimba
2
3 Kodwa-ke, le mfuneko kungenzeka ingahlangatshezwa yiwo wonke ama-switch
I-4. Izibuko zePort Izidingo okufanele zilungiselelwe ekushintsheni. Lapho izindawo zibhekwe zidinga ukulungiswa, ukushintshwa kudinga ukulungiswa kabusha.
