A Network Tap, yomwe imadziwikanso kuti Ethernet Tap, Copper Tap kapena Data Tap, ndi chipangizo chomwe chimagwiritsidwa ntchito pamanetiweki a Ethernet kuti mugwire ndikuwunika kuchuluka kwa magalimoto pamaneti. Zapangidwa kuti zipereke mwayi wopeza deta yomwe ikuyenda pakati pa zida zapaintaneti popanda kusokoneza ntchito ya intaneti.
Cholinga chachikulu cha tap ya netiweki ndikufanizira mapaketi a netiweki ndikuwatumiza ku chipangizo chowunikira kuti awunikenso kapena zolinga zina. Nthawi zambiri imayikidwa pamzere pakati pa zida za netiweki, monga masiwichi kapena ma router, ndipo imatha kulumikizidwa ndi chipangizo chowunikira kapena chowunikira maukonde.
Ma Network Taps amabwera m'mitundu yonse ya Passive ndi Active:
1.Passive Network Taps: Mapampu a netiweki osafunikira safuna mphamvu zakunja ndipo amagwira ntchito pogawanitsa kapena kubwereza kuchuluka kwa maukonde. Amagwiritsa ntchito njira monga kuphatikizika kwa kuwala kapena kugwirizanitsa magetsi kuti apange kopi ya mapaketi omwe akuyenda pa ulalo wa netiweki. Mapaketi obwereza amatumizidwa ku chipangizo chowunikira, pomwe mapaketi oyambira amapitilira kufalikira kwawo kwanthawi zonse.
Magawo omwe amagawanika omwe amagwiritsidwa ntchito mu Passive Network Taps amatha kusiyanasiyana kutengera ntchito ndi zofunikira. Komabe, pali mitundu ingapo yogawanitsa yomwe imapezeka kawirikawiri m'kuchita:
50:50
Ichi ndi chiŵerengero chogawanika chokhazikika pamene chizindikiro cha kuwala chimagawidwa mofanana, ndi 50% kupita ku netiweki yaikulu ndipo 50% imayikidwa kuti iwonetsedwe. Imapereka mphamvu yofananira yamagetsi panjira zonse ziwiri.
70:30
Pachiŵerengero ichi, pafupifupi 70% ya chizindikiro cha kuwala imayendetsedwa ku intaneti yaikulu, pamene 30% yotsalayo imayikidwa kuti iwonetsedwe. Amapereka gawo lokulirapo la chizindikiro cha netiweki yayikulu pomwe amalolabe kuthekera kowunika.
90:10
Chiŵerengerochi chimagawira ma siginecha ambiri, mozungulira 90%, ku netiweki yayikulu, ndi 10% yokha yomwe imayikidwa kuti iwunikire. Imayika patsogolo kukhulupirika kwa ma netiweki akuluakulu pomwe ikupereka gawo laling'ono lowunikira.
95:05
Mofanana ndi chiŵerengero cha 90:10, chiŵerengero chogawanikachi chimatumiza 95% ya chizindikiro cha kuwala ku intaneti yaikulu ndikusungira 5% kuti iwonetsedwe. Amapereka mphamvu zochepa pa chizindikiro chachikulu cha intaneti pamene akupereka gawo laling'ono la kusanthula kapena kuyang'anira zosowa.
2.Active Network Taps: Makapu a netiweki omwe akugwira ntchito, kuwonjezera pa kubwereza mapaketi, amaphatikiza magawo omwe akugwira ntchito ndi ma circuitry kuti apititse patsogolo magwiridwe antchito. Atha kupereka zinthu zapamwamba monga kusefa kwa magalimoto, kusanthula kwa protocol, kusanja kwa katundu, kapena kuphatikizira paketi. Ma tapi omwe amagwira ntchito nthawi zambiri amafuna mphamvu zakunja kuti agwiritse ntchito zina zowonjezerazi.
Network Taps imathandizira ma protocol osiyanasiyana a Ethernet, kuphatikiza Ethernet, TCP/IP, VLAN, ndi ena. Amatha kuthana ndi liwiro losiyanasiyana la netiweki, kuyambira pa liwiro lotsika ngati 10 Mbps kupita ku liwiro lapamwamba ngati 100 Gbps kapena kupitilira apo, kutengera mtundu wapampopi komanso kuthekera kwake.
Magalimoto omwe agwidwa atha kugwiritsidwa ntchito powunika maukonde, kuthana ndi zovuta pamanetiweki, kusanthula magwiridwe antchito, kuzindikira zowopsa zachitetezo, ndikuchita maumboni amanetiweki. Ma tap a pa netiweki amagwiritsidwa ntchito kwambiri ndi oyang'anira maukonde, akatswiri achitetezo, ndi ofufuza kuti adziwe momwe maukonde amagwirira ntchito ndikuwonetsetsa kuti maukonde akuyenda, chitetezo, komanso kutsatira.
Ndiye, pali kusiyana kotani pakati pa Passive Network Tap ndi Active Network Tap?
A Passive Network Tapndi chipangizo chosavuta chomwe chimabwereza mapaketi a netiweki popanda luso lowonjezera ndipo sichifuna mphamvu zakunja.
An Active Network Tap, kumbali ina, imaphatikizapo zigawo zogwira ntchito, zimafuna mphamvu, ndipo zimapereka zida zapamwamba kuti ziwonetsedwe ndi kusanthula kwathunthu kwa intaneti. Kusankha pakati pa ziwirizi kumadalira zofunikira zowunikira, ntchito zomwe mukufuna, ndi zinthu zomwe zilipo.
