Kuti muwunikire kuchuluka kwa anthu pamanetiweki, monga kusanthula machitidwe a ogwiritsa ntchito pa intaneti, kuyang'anira kuchuluka kwa magalimoto pamsewu, ndi kuyang'anira ma netiweki, muyenera kusonkhanitsa kuchuluka kwa anthu pamanetiweki. Kujambula kuchuluka kwa magalimoto pa netiweki kungakhale kolakwika. M'malo mwake, muyenera kutengera kuchuluka kwa magalimoto apaintaneti ndikutumiza ku chipangizo chowunikira. Network splitter, yomwe imadziwikanso kuti Network TAP. Zimangogwira ntchito imeneyi. Tiyeni tiwone tanthauzo la Network TAP:
I. Network Tap ndi chipangizo cha hardware chomwe chimapereka njira yopezera deta yomwe ikuyenda pa netiweki yamakompyuta.(kuchokera ku wikipedia)
II. ANetwork Tap, yomwe imadziwikanso kuti Test Access Port, ndi chipangizo cha hardware chomwe chimalumikiza chingwe cha Network ndikutumiza chidutswa cha Kuyankhulana kwa Network ku zipangizo zina. Magulu ophatikizira ma network amagwiritsidwa ntchito kwambiri mu network intrusion monitoring systems (IPS), zowunikira pa netiweki, ndi ma profiler. Kubwereza kuyankhulana kuzipangizo zamagetsi tsopano kumachitika kudzera pa switching port analyzer (span port), yomwe imadziwikanso kuti port mirroring mu network switching.
III. Ma Network Taps amagwiritsidwa ntchito kupanga madoko ofikira osatha kuti awonedwe mosasamala. Pompopi, kapena Test Access Port, ikhoza kukhazikitsidwa pakati pa zida ziwiri zilizonse za netiweki, monga masiwichi, ma routers ndi ma firewall. Itha kugwira ntchito ngati doko lolowera pa chipangizo chowunikira chomwe chimagwiritsidwa ntchito kusonkhanitsa deta yapamzere, kuphatikiza njira yodziwira Intrusion, Intrusion prevention system yomwe imayikidwa mumayendedwe okhazikika, ma protocol analyzers ndi zida zowunikira kutali. (kuchokera ku NetOptics).
Kuchokera ku matanthauzo atatu omwe ali pamwambawa, titha kujambula mawonekedwe angapo a Network TAP: hardware, inline, transparent
Tawonani izi:
1. Ndi gawo lodziyimira pawokha la Hardware, ndipo chifukwa cha ichi, silikhala ndi mphamvu pa katundu wa zida zomwe zilipo kale, zomwe zili ndi zabwino zambiri kuposa kuyang'ana doko.
2. Ndi chipangizo chapamzere. Mwachidule, ziyenera kulumikizidwa ndi intaneti, zomwe zitha kumveka. Komabe, izi zimakhalanso ndi vuto loyambitsa mfundo yolephereka, ndipo chifukwa ndi chipangizo cha intaneti, intaneti yamakono iyenera kusokonezedwa panthawi yotumizira, malingana ndi kumene imayikidwa.
3. Transparent imatanthawuza cholozera ku netiweki yamakono. Kufikira ma netiweki pambuyo pa shunt, netiweki yomwe ilipo pazida zonse, ilibe chilichonse, kwa iwo imawonekeratu, imakhalanso ndi network shunt send traffic kuti iwunikire zida, chipangizo chowunikira pa netiweki chimawonekera, chili ngati ngati muli ndi mwayi watsopano wopita kumagetsi atsopano, kwa zipangizo zina zomwe zilipo, Palibe chimene chimachitika, kuphatikizapo pamene mumachotsa chipangizocho ndikukumbukira mwadzidzidzi ndakatuloyo, "Sungani manja anu osati mtambo"......
Anthu ambiri amadziwa za port mirroring. Inde, kuyang'ana pa doko kungathenso kukwaniritsa zomwezo. Nayi kufananitsa pakati pa Network Taps/Diverters ndi Port Mirroring:
1. Monga doko la chosinthira palokha adzasefa ena mapaketi zolakwika ndi mapaketi ndi kukula kochepa, doko mirroring sikungatsimikizire kuti magalimoto onse angapezeke. Komabe, shunter imatsimikizira kukhulupirika kwa deta chifukwa "yakopera" kwathunthu pagawo la thupi
2. Pankhani ya zochitika zenizeni, pazitsulo zina zotsika, kuyang'ana pa doko kungayambitse kuchedwa pamene kukopera magalimoto kumalo owonetsera magalasi, komanso kumayambitsa kuchedwa pamene ikopera madoko a 10 / 100m ku madoko a GIGA.
3. Kuyika magalasi pamadoko kumafuna kuti bandwidth ya doko lowoneka bwino ikhale yayikulu kuposa kapena yofanana ndi kuchuluka kwa mayendedwe a madoko onse owonetsedwa. Komabe, izi sizingakwaniritsidwe ndi masiwichi onse
4. Port mirroring iyenera kukhazikitsidwa pa switch. Pomwe madera omwe akuyenera kuyang'aniridwa akuyenera kusinthidwa, kusinthaku kumayenera kukonzedwanso.
