Ndine chokwadi chekuti unoziva kurwira pakati peNetwork Tap (Test Access Point) uye switch port analyzer (SPAN port) yeNetiweki yekutarisa zvinangwa. Vese vane hunyanzvi hwekutarisa traffic pane network uye kuitumira kune kunze-kwe-bhendi kuchengetedza maturusi senge intrusion yekuona masisitimu, network logger, kana network analyzer. Span ports inogadziriswa panetiweki bhizinesi switch ine port mirroring basa. Iyo chiteshi chakatsaurirwa pane inogadziriswa switch inotora girazi kopi yetiweki traffic kubva kuchinjika kutumira kune yekuchengetedza maturusi. A TAP, kune rumwe rutivi, chishandiso chinongo govera network traffic kubva kunetiweki kuenda kune yekuchengetedza chishandiso. TAP inogamuchira network traffic munzira mbiri munguva chaiyo uye pane yakaparadzana chiteshi.
Aya ndiwo mabhenefiti mashanu makuru eTAP kuburikidza nechiteshi cheSPAN:
1. TAP inobata pakiti imwe neimwe!
Span Inodzima mapaketi akaora uye mapaketi madiki pane mashoma saizi. Naizvozvo, maturusi ekuchengetedza haagone kugashira traffic yese nekuti span ports inopa yakanyanya kukosha kune network traffic. Pamusoro pezvo, RX neTX traffic yakaunganidzwa pachiteshi chimwe chete, saka mapaketi anowanzo kudonhedzwa. TAP inobata ese-maviri-nzira traffic pane yega yega inonangwa chiteshi, kusanganisira zvikanganiso zvechiteshi.
2. Yakakwana passive solution, hapana IP configuration kana magetsi anodiwa
Passive TAP inonyanya kushandiswa mune fiber optic network. Mune passive TAP, inogamuchira traffic kubva kumativi ese etiweki uye inotsemura mwenje unouya kuitira kuti 100% yetraffic ionekwe pachishandiswa chekutarisa. Passive TAP haidi chero magetsi. Nekuda kweizvozvo, ivo vanowedzera dhizaini redundancy, inoda kugadziridzwa kushoma, uye kuderedza mutengo wakazara. Kana ukaronga kutarisa mhangura Ethernet traffic, unofanirwa kushandisa inoshanda TAP. Active TAP inoda magetsi, asi Niagra's Active TAP inosanganisira kutadza-safe bypass tekinoroji inobvisa njodzi yekuvhiringwa kwesevhisi kana magetsi akadzimwa.
3. Zero packet kurasikirwa
Network TAP inotarisisa migumo yese yekubatanidza kuti ipe 100% kuoneka kwenzira mbiri network traffic. TAP haina kurasa chero mapaketi, zvisinei nebandwidth yawo.
4. Inokodzera kushandiswa kwepakati kusvika kune yakakwirira network
Iyo SPAN port haigone kugadzirisa anoshandiswa zvakanyanya network network pasina kudonhedza mapaketi. Naizvozvo, network TAP inodiwa mune idzi kesi. Kana traffic yakawanda ichiyerera kubva muSPAN pane iri kutambirwa, chiteshi cheSPAN chinova chakawandisa uye chinomanikidzwa kurasa mapaketi. Kuti ubate 10Gb yenzira mbiri, chiteshi cheSPAN chinoda 20Gb yehutano, uye 10Gb Network TAP ichakwanisa kutora zvose 10Gb yehutano.
5. TAP Inobvumira traffic yese kuti ipfuure, kusanganisira VLAN tags
Span ports kazhinji haitenderi maVLAN mavara kupfuura, izvo zvinoita kuti zviome kuona matambudziko eVLAN uye kugadzira matambudziko emanyepo. TAP inodzivirira matambudziko akadai nekubvumira traffic yese kupinda.
