Ukujonga itrafikhi yothungelwano, njengohlalutyo lokuziphatha lomsebenzisi kwi-intanethi, ukujonga okungaqhelekanga kwetrafikhi, kunye nokujongwa kwesicelo sothungelwano, kufuneka uqokelele itrafikhi yenethiwekhi.Ukubamba itrafikhi yenethiwekhi kunokuba kungachanekanga.Enyanisweni, kufuneka ukhuphele i-traffic yenethiwekhi yangoku kwaye uyithumele kwisixhobo sokubeka iliso.I-Splitter yenethiwekhi, eyaziwa ngokuba yi-Network TAP.Iyawenza nje lo msebenzi.Makhe sijonge inkcazo ye-Network TAP:

I. Network Tap sisixhobo sehardware esibonelela ngendlela yokufikelela kwidata equkuqelayo kwinethiwekhi yekhompyuter.(isuka kwiwikipedia)

II.AItephu yeNethiwekhi, ekwaziwa ngokuba yiPort Access yoVavanyo, sisixhobo se-hardware esiplaga ngqo kwintambo yoMnatha kwaye ithumela iqhekeza lonxibelelwano lweNethiwekhi kwezinye izixhobo.Izahluli zenethiwekhi ziqhele ukusetyenziswa kwiinkqubo zokubona ukungena kwenethiwekhi (IPS), iziboni zenethiwekhi, kunye neeprofayili.Ukuphindaphinda unxibelelwano kwizixhobo zothungelwano ngoku ngokuqhelekileyo kwenziwa ngokutshintsha isihlalutyi sezibuko (i-span port), eyaziwa ngokuba sisibuko sesibuko kuthungelwano lokutshintsha.

III.Iitephu zeNethiwekhi zisetyenziselwa ukwenza amazibuko ofikelelo ngokusisigxina ukwenzela uqwalaselo lokwenziwa.Itephu, okanye i-Port Access yoVavanyo, inokusetwa phakathi kwazo naziphi na izixhobo ezibini zenethwekhi, ezifana nokutshintsha, iirutha kunye neendonga zomlilo.Inokusebenza njengechweba lokufikelela kwisixhobo sokubeka iliso esisetyenziselwa ukuqokelela idatha ye-in-line, kubandakanywa nenkqubo yokufumanisa i-Intrusion, inkqubo yokukhusela i-Intrusion esetyenziswe kwimodi yokwenziwa, abahlalutyi beprotocol kunye nezixhobo zokubeka iliso ezikude.(ukusuka kwi-NetOptics).
