Ndeupi musiyano uripo pakati pePassive Network Tap uye Active Network Tap?

A Network Tap, inozivikanwawo seEthernet Tap, Copper Tap kana Data Tap, chishandiso chinoshandiswa muEthernet-based network kutora uye kutarisa network traffic.Yakagadzirirwa kupa mukana kune iyo data inoyerera pakati petiweki zvishandiso pasina kukanganisa kushanda kwetiweki.

Chinangwa chekutanga chetiweki tapi ndeye kudzokorora mapaketi etiweki uye nekuatumira kune chigadziriso chekuongorora kana zvimwe zvinangwa.Iyo inowanzo kuisirwa mu-mutsara pakati petiweki zvishandiso, senge switch kana ma router, uye inogona kubatanidzwa kune yekutarisa mudziyo kana network analyzer.

Network Taps inouya mune ese ari maviri Passive uye Active akasiyana:

1.Passive Network Taps: Passive network matepi haadi simba rekunze uye anoshanda chete nekutsemura kana kudzokorora traffic network.Vanoshandisa matekiniki akaita sekubatanidza optical kana kuenzanisa kwemagetsi kugadzira kopi yemapaketi anoyerera nepanetiweki link.Mapaketi akadhindwa anozoendeswa kune yekutarisisa mudziyo, nepo epakutanga mapaketi achienderera mberi nekutapurirana kwawo.

Iwo akajairwa kupatsanura ratios anoshandiswa muPassive Network Taps anogona kusiyana zvichienderana neiyo chaiyo application uye zvinodiwa.Nekudaro, kune mashoma akajairwa kupatsanura ratios anowanzo kusangana mukuita:

50:50

Iyi ireshiyo yekukamura yakaenzana uko chiratidzo chemaziso chakakamurwa zvakaenzana, ne50% ichienda kunetiweki huru uye 50% ichibatwa kuti itariswe.Inopa yakaenzana chiratidzo chesimba kune ese makwara.

70:30

Muchiyero ichi, inenge 70% yechiratidzo chemaziso chinotungamirirwa kunetiweki huru, nepo 30% yakasara inobatwa kuti iongorore.Inopa chikamu chakakura chechiratidzo chetiweki huru ichiri kubvumira kugona kwekutarisa.

90:10

Ichi chiyero chinogovera ruzhinji rwechiratidzo chemaziso, chakakomberedza 90%, kunetiweki huru, iine gumi muzana chete iri kubatwa nekuda kwekutarisa.Inoisa pamberi pechiratidzo chekuvimbika kune network huru ichipa chikamu chidiki chekutarisa.

95:05

Zvakafanana nereshiyo ye90:10, iyi kupatsanura chiyero inotumira 95% yechiratidzo chemaziso kune network huru uye inochengeta 5% yekutarisa.Inopa hushoma hunoita pane huru network chiratidzo ichipa chikamu chidiki chekuongorora kana chekutarisa zvinodiwa.

 

 

 

 

2.Active Network Taps: Active network matepi, kuwedzera pakudzokorora mapaketi, anosanganisira anoshanda zvinoriumba uye masekete kuti awedzere kushanda kwawo.Ivo vanogona kupa epamberi maficha senge traffic kusefa, kuongororwa kweprotocol, kuyera kuyera, kana kuunganidzwa kwepakiti.Mapombi anoshanda kazhinji anoda simba rekunze kuti ashandise mamwe mabasa aya.

Network Taps inotsigira akasiyana Ethernet mapuroteni, anosanganisira Ethernet, TCP/IP, VLAN, nevamwe.Vanokwanisa kubata zvakasiyana-siyana zvekumhanya kwenetiweki, kubva pakumhanya kwakaderera senge 10 Mbps kusvika kumhanyiro yepamusoro se100 Gbps kana kupfuura, zvichienderana neiyo chaiyo tap modhi uye kugona kwayo.

Iyo yakatorwa network traffic inogona kushandiswa kutarisisa network, kugadzirisa matambudziko netiweki, kuongorora mashandiro, kuona kutyisidzira kwekuchengetedza, uye kuita network forensics.Matepi etiweki anowanzo shandiswa nevanetiweki maneja, nyanzvi dzekuchengetedza, uye vaongorori kuti vawane nzwisiso mumaitiro etiweki uye kuona kushanda kwenetiweki, kuchengetedzeka, uye kutevedzera.
