Ndikukhulupirira kuti mukudziwa kulimbana pakati pa Network Tap(Test Access Point) ndi switch port analyzer (SPAN port) pazolinga zowunikira Network. Onsewa ali ndi kuthekera kowonera kuchuluka kwa magalimoto pa netiweki ndikutumiza ku zida zachitetezo zomwe zili kunja kwa gulu monga makina ozindikira ma intrusion, odula ma network, kapena ma analyzer a network. Madoko a Span amapangidwa pa masiwichi abizinesi apaintaneti omwe ali ndi ntchito yoyang'anira doko. Ndilo doko lodzipatulira pa switch yoyendetsedwa yomwe imatenga kope lagalasi la magalimoto apaintaneti kuchokera pakusintha kupita ku zida zachitetezo. A TAP, kumbali ina, ndi chipangizo chomwe chimagawira mosavuta kuchuluka kwa maukonde kuchokera pa netiweki kupita ku chida chachitetezo. TAP imalandira kuchuluka kwa maukonde mbali zonse ziwiri munthawi yeniyeni komanso panjira ina.
Izi ndi zabwino zisanu za TAP kudzera pa doko la SPAN:
1. TAP imagwira paketi iliyonse!
Span Imachotsa mapaketi ovunda ndi mapaketi ang'onoang'ono kuposa kukula kwake. Chifukwa chake, zida zachitetezo sizingalandire kuchuluka kwa magalimoto onse chifukwa madoko a span amapereka patsogolo kwambiri kuchuluka kwa maukonde. Kuphatikiza apo, magalimoto a RX ndi TX amaphatikizidwa padoko limodzi, kotero mapaketi amatha kugwetsedwa. TAP imagwira magalimoto anjira ziwiri padoko lililonse, kuphatikiza zolakwika zamadoko.
2. Yankho lokhazikika, palibe kasinthidwe ka IP kapena magetsi ofunikira
Passive TAP imagwiritsidwa ntchito makamaka mu fiber optic network. Mu TAP yopanda kanthu, imalandira magalimoto kuchokera kumbali zonse ziwiri za intaneti ndikugawa kuwala komwe kukubwera kuti 100% ya magalimoto iwoneke pa chida chowunikira. Passive TAP safuna magetsi. Zotsatira zake, amawonjezera kusanjikiza, amafunikira kusamalidwa pang'ono, ndikuchepetsa ndalama zonse. Ngati mukufuna kuyang'anira kuchuluka kwa Ethernet yamkuwa, muyenera kugwiritsa ntchito TAP yogwira. Active TAP imafuna magetsi, koma Active TAP ya Niagra imaphatikizanso ukadaulo wopumira wotetezedwa womwe umachotsa chiwopsezo cha kusokonezeka kwa ntchito ngati magetsi azimitsidwa.
3. Kutayika kwa paketi ya Zero
Network TAP imayang'anira malekezero onse a ulalo kuti apereke mawonekedwe a 100% a njira ziwiri zama network. TAP sichitaya mapaketi aliwonse, mosasamala kanthu za bandwidth yawo.
4. Yoyenera kugwiritsa ntchito maukonde apakati mpaka apamwamba
Doko la SPAN silingathe kukonza maulalo a netiweki omwe amagwiritsidwa ntchito kwambiri popanda kutaya mapaketi. Chifukwa chake, TAP ya netiweki ndiyofunikira pamilandu iyi. Ngati magalimoto ambiri atuluka mu SPAN kuposa momwe akulandirira, doko la SPAN limakhala lolembetsedwa kwambiri ndipo amakakamizika kutaya mapaketi. Kuti mugwire 10Gb ya magalimoto awiri, doko la SPAN likufunika 20Gb ya mphamvu, ndipo 10Gb Network TAP idzatha kutenga mphamvu zonse za 10Gb.
5. TAP Imalola magalimoto onse kudutsa, kuphatikiza ma tag a VLAN
Madoko a Span nthawi zambiri salola kuti zilembo za VLAN zidutse, zomwe zimapangitsa kuti zikhale zovuta kuzindikira zovuta za VLAN ndikupanga zovuta zabodza. TAP imapewa zovuta zotere polola magalimoto onse kudutsa.
