Kuti muwone kuchuluka kwa magalimoto pa intaneti, monga kusanthula khalidwe la ogwiritsa ntchito pa intaneti, kuyang'anira magalimoto molakwika, ndi kuyang'anira mapulogalamu a pa intaneti, muyenera kusonkhanitsa kuchuluka kwa magalimoto pa intaneti. Kujambula kuchuluka kwa magalimoto pa intaneti kungakhale kolakwika. Ndipotu, muyenera kukopera kuchuluka kwa magalimoto pa intaneti ndikutumiza ku chipangizo chowunikira. Network splitter, yomwe imadziwikanso kuti Network TAP. Imagwira ntchito imeneyi. Tiyeni tiwone tanthauzo la Network TAP:
I. Network Tap ndi chipangizo cha hardware chomwe chimapereka njira yopezera deta yomwe ikuyenda pa netiweki ya kompyuta. (kuchokera ku wikipedia)
II. AKudina pa Netiweki, yomwe imadziwikanso kuti Test Access Port, ndi chipangizo cha hardware chomwe chimalumikizidwa mwachindunji mu chingwe cha Network ndikutumiza gawo la kulumikizana kwa Network kuzipangizo zina. Ma splitter a network amagwiritsidwa ntchito kwambiri mu network intrusion detection systems (IPS), network detectors, ndi profilers. Kubwerezabwereza kulumikizana kuzipangizo za network tsopano kumachitika kudzera mu switching port analyzer (span port), yomwe imadziwikanso kuti port mirroring mu network switching.
III. Ma Network Taps amagwiritsidwa ntchito popanga ma access ports okhazikika kuti aziyang'anira zinthu mopanda kusokoneza. Tap, kapena Test Access Port, ikhoza kukhazikitsidwa pakati pa zipangizo ziwiri za netiweki, monga ma switch, ma routers ndi ma firewall. Itha kugwira ntchito ngati access port ya chipangizo choyang'anira chomwe chimagwiritsidwa ntchito kusonkhanitsa deta yapaintaneti, kuphatikiza njira yodziwira kulowerera, njira yopewera kulowerera yomwe imagwiritsidwa ntchito mu passive mode, protocol analyzers ndi zida zowunikira zakutali. (kuchokera ku NetOptics).
Kuchokera ku matanthauzidwe atatu omwe ali pamwambapa, titha kupeza mawonekedwe angapo a Network TAP: hardware, inline, transparent
Nayi mawonekedwe a zinthu izi:
1. Ndi chida chodziyimira pawokha, ndipo chifukwa cha izi, sichikhudza katundu wa zida za netiweki zomwe zilipo, zomwe zili ndi ubwino waukulu kuposa ma mirroring a ma port
2. Ndi chipangizo chomwe chili pa intaneti. Mwachidule, chiyenera kulumikizidwa ku netiweki, zomwe tingamvetse. Komabe, izi zilinso ndi vuto loyambitsa vuto, ndipo chifukwa ndi chipangizo cha pa intaneti, netiweki yomwe ilipo iyenera kusokonezedwa nthawi yogwiritsira ntchito, kutengera komwe yagwiritsidwa ntchito.
3. Transparent imatanthauza cholozera ku netiweki yomwe ilipo. Ma netiweki olowera pambuyo pa shunt, netiweki yomwe ilipo ya zida zonse, siili ndi mphamvu iliyonse, kwa iwo ndi yowonekera bwino, ndithudi, ilinso ndi netiweki shunt tumizani magalimoto kuti aziyang'anira zida, chipangizo chowunikira netiweki ndi chowonekera, zili ngati muli mu mwayi watsopano wopeza soketi yatsopano yamagetsi, ya zida zina zomwe zilipo, Palibe chomwe chimachitika, kuphatikizapo mukachotsa chipangizocho ndikukumbukira ndakatulo yakuti, "Weebetsani dzanja lanu osati mtambo"......
Anthu ambiri amadziwa bwino za ma port mirroring. Inde, ma port mirroring nawonso angathandize chimodzimodzi. Nayi kufananiza pakati pa Network Taps/Diverters ndi Port Mirroring:
1. Popeza doko la switch palokha lidzasefa mapaketi ena olakwika ndi mapaketi omwe ali ndi kukula kochepa kwambiri, kuwunika ma port mirroring sikungatsimikizire kuti magalimoto onse angapezeke. Komabe, shunter imatsimikizira kukhulupirika kwa deta chifukwa "yakopedwa" kwathunthu pagawo lenilenilo.
2. Ponena za magwiridwe antchito enieni, pa ma switch ena otsika, ma port mirroring angabweretse kuchedwa akamakopera magalimoto kupita ku ma mirroring ports, komanso amayambitsa kuchedwa akamakopera ma 10/100m kupita ku ma GIGA ports
3. Kuyerekeza ma port kumafuna kuti bandwidth ya doko lojambulidwa ikhale yayikulu kuposa kapena yofanana ndi kuchuluka kwa ma bandwidth a ma port onse ojambulidwa. Komabe, izi sizingakwaniritsidwe ndi ma switch onse.
4. Kujambula ma doko kuyenera kukonzedwa pa switch. Malo omwe akuyenera kuyang'aniridwa akafunika kusinthidwa, switch iyenera kukonzedwanso.
