Kodi pali kusiyana kotani pakati pa Passive Network Tap ndi Active Network Tap?

A Kudina pa Netiweki, yomwe imadziwikanso kuti Ethernet Tap, Copper Tap kapena Data Tap, ndi chipangizo chomwe chimagwiritsidwa ntchito m'ma netiweki ozikidwa pa Ethernet kuti chigwire ndikuyang'anira kuchuluka kwa magalimoto pa netiweki. Chapangidwa kuti chipereke mwayi wopeza deta yomwe ikuyenda pakati pa zida za netiweki popanda kusokoneza ntchito ya netiweki.

Cholinga chachikulu cha kukhudza netiweki ndikubwereza mapaketi a netiweki ndikutumiza ku chipangizo chowunikira kuti chiwunikidwe kapena zolinga zina. Nthawi zambiri chimayikidwa pamzere pakati pa zida za netiweki, monga ma switch kapena ma rauta, ndipo chimatha kulumikizidwa ku chipangizo chowunikira kapena chowunikira netiweki.

Ma Network Taps amabwera m'mitundu yonse ya Passive ndi Active:

1.Ma Tap a Network Opanda Ntchito: Ma tap a netiweki osagwiritsa ntchito mphamvu safuna mphamvu yakunja ndipo amagwira ntchito pogawa kapena kubwerezabwereza kuchuluka kwa magalimoto a netiweki. Amagwiritsa ntchito njira monga kulumikizana kwa kuwala kapena kulinganiza magetsi kuti apange kopi ya mapaketi omwe akuyenda kudzera mu ulalo wa netiweki. Mapaketi obwerezabwereza amatumizidwa ku chipangizo chowunikira, pomwe mapaketi oyambilira amapitiliza kutumiza kwawo kwanthawi zonse.

Ma ratio ogawa magawo omwe amagwiritsidwa ntchito mu Passive Network Taps amatha kusiyana kutengera momwe akugwiritsira ntchito komanso zofunikira zake. Komabe, pali ma ratio ochepa ogawa magawo omwe amapezeka nthawi zambiri:

50:50

Ichi ndi chiŵerengero chogawanika bwino komwe chizindikiro cha kuwala chimagawidwa mofanana, ndipo 50% imapita ku netiweki yayikulu ndipo 50% imagwiritsiridwa ntchito poyang'anira. Chimapereka mphamvu yofanana ya chizindikiro panjira zonse ziwiri.

70:30

Mu chiŵerengero ichi, pafupifupi 70% ya chizindikiro cha kuwala chimalunjika ku netiweki yayikulu, pomwe 30% yotsalayo imagwiritsidwa ntchito poyang'anira. Imapereka gawo lalikulu la chizindikiro cha netiweki yayikulu pomwe imalolabe kuthekera koyang'anira.

90:10

Chiŵerengerochi chimagawa chizindikiro chachikulu cha kuwala, pafupifupi 90%, ku netiweki yayikulu, ndipo 10% yokha ndi yomwe imagwiritsidwa ntchito poyang'anira. Chimaika patsogolo umphumphu wa chizindikiro pa netiweki yayikulu pomwe chimapereka gawo laling'ono loyang'anira.

95:05

Mofanana ndi chiŵerengero cha 90:10, chiŵerengero chogawanikachi chimatumiza 95% ya chizindikiro chowunikira ku netiweki yayikulu ndipo chimasunga 5% kuti chiziyang'aniridwa. Chimapereka mphamvu yochepa pa chizindikiro chachikulu cha netiweki pomwe chimapereka gawo laling'ono la zosowa zowunikira kapena kuyang'aniridwa.

 

 

 

 

2.Ma Tap a Network Ogwira Ntchito: Ma tap a netiweki ogwira ntchito, kuwonjezera pa kubwereza mapaketi, amaphatikizapo zigawo zogwira ntchito ndi ma circuitry kuti awonjezere magwiridwe antchito awo. Amatha kupereka zinthu zapamwamba monga kusefa magalimoto, kusanthula kwa protocol, kulinganiza katundu, kapena kuphatikiza mapaketi. Ma tap ogwira ntchito nthawi zambiri amafunikira mphamvu zakunja kuti agwire ntchito zina izi.

Ma Network Taps amathandizira ma protocol osiyanasiyana a Ethernet, kuphatikiza Ethernet, TCP/IP, VLAN, ndi ena. Amatha kuthana ndi liwiro losiyana la netiweki, kuyambira liwiro lotsika monga 10 Mbps mpaka liwiro lokwera ngati 100 Gbps kapena kuposerapo, kutengera mtundu wa tap womwe wagwiritsidwa ntchito komanso kuthekera kwake.

Ma network omwe agwidwa angagwiritsidwe ntchito poyang'anira ma network, kuthetsa mavuto a ma network, kusanthula momwe zinthu zikuyendera, kuzindikira zoopsa zachitetezo, komanso kuchita kafukufuku wa ma network. Ma network taps nthawi zambiri amagwiritsidwa ntchito ndi oyang'anira ma network, akatswiri achitetezo, ndi ofufuza kuti apeze chidziwitso cha momwe ma network amagwirira ntchito ndikuwonetsetsa kuti ma network akugwira ntchito bwino, otetezeka, komanso kutsatira malamulo.
