Nzi neza ko uzi urugamba hagati ya Network Tap (Ikigereranyo cyo Kugerageza) hamwe nuwasesenguye icyambu (icyambu cya SPAN) kugirango agenzure Network. Byombi bifite ubushobozi bwo kwerekana indorerwamo kuri neti no kubyohereza mubikoresho byumutekano bitari hanze nka sisitemu yo gutahura kwinjira, abinjira mumurongo, cyangwa abasesengura imiyoboro. Icyambu cya Span cyashyizwe kumurongo uhuza imishinga ifite imikorere yicyerekezo. Nicyambu cyabugenewe kuri switch icungwa ifata indorerwamo kopi yumuhanda uva kumurongo kugirango wohereze kubikoresho byumutekano. Ku rundi ruhande, TAP, ni igikoresho gikwirakwiza mu buryo bworoshye urujya n'uruza rw'umuyoboro uva ku muyoboro ujya ku gikoresho cy'umutekano. TAP yakira traffic traffic mubyerekezo byombi mugihe nyacyo no kumuyoboro utandukanye.
Izi ninyungu eshanu zingenzi za TAP zinyuze ku cyambu cya SPAN:
1. TAP ifata buri paki imwe!
Span Gusiba ibintu byangiritse nibipaki bito kurenza ubunini buke. Kubwibyo, ibikoresho byumutekano ntibishobora kwakira traffic zose kuko ibyambu bya span biha umwanya munini traffic traffic. Mubyongeyeho, traffic RX na TX byegeranijwe ku cyambu kimwe, bityo paki zirashobora kugabanuka. TAP ifata inzira-ebyiri zose kuri buri cyambu, harimo amakosa yicyambu.
2. Igisubizo cyuzuye gusa, nta IP iboneza cyangwa amashanyarazi akenewe
Passive TAP ikoreshwa cyane cyane mumiyoboro ya fibre optique. Muri pasiporo ya TAP, yakira traffic kuva mubyerekezo byombi byurusobe kandi igabanya urumuri rwinjira kuburyo 100% yimodoka igaragara kubikoresho byo gukurikirana. Passive TAP ntabwo isaba amashanyarazi ayo ari yo yose. Nkigisubizo, bongeraho urwego rwubucucike, bisaba kubungabungwa bike, no kugabanya ibiciro muri rusange. Niba uteganya gukurikirana umuringa wa Ethernet, ugomba gukoresha TAP ikora. TAP ikora isaba amashanyarazi, ariko Niagra's Active TAP ikubiyemo tekinoroji ya bypass itagira umutekano ikuraho ibyago byo guhungabanya serivisi mugihe habaye umuriro.
3. Gutakaza paki ya zeru
Umuyoboro TAP ukurikirana impera zombi zumuhuza kugirango utange 100% kugaragara kumurongo wibice bibiri. TAP ntishobora guta paki iyo ari yo yose, tutitaye ku burebure bwayo.
4. Birakwiriye gukoresha imiyoboro mito n'iciriritse
Icyambu cya SPAN ntigishobora gutunganya imiyoboro ikoreshwa cyane idataye paki. Kubwibyo, umuyoboro TAP urasabwa muribi bihe. Niba ibinyabiziga byinshi bisohoka muri SPAN kuruta kwakirwa, icyambu cya SPAN gihinduka abiyandikishije kandi bigahatirwa guta paki. Kugirango ufate 10Gb yimodoka ebyiri, icyambu cya SPAN gikeneye 20Gb yubushobozi, kandi 10Gb Network TAP izashobora gufata 10Gb yubushobozi bwose.
5. TAP Emerera traffic yose kunyura, harimo tagi ya VLAN
Icyambu cya Span muri rusange ntabwo cyemerera ibirango bya VLAN kurengana, bigatuma bigorana kumenya ibibazo bya VLAN no guteza ibibazo bogus. TAP irinda ibibazo nkibi yemerera traffic yose kunyuramo.
