Menene TAP na Network?
Wataƙila kun fara jin sunan TAP switch. TAP (Terminal Access Point), wanda aka fi sani da NPB (Network Packet Broker), ko Tap Aggregator?
Babban aikin TAP shine saita tsakanin tashar madubi a kan hanyar sadarwa ta samarwa da kuma rukunin na'urar bincike. TAP tana tattara zirga-zirgar madubi ko rabe-raben na'urorin sadarwa na samarwa ɗaya ko fiye kuma tana rarraba zirga-zirgar zuwa ɗaya ko fiye na na'urorin nazarin bayanai.
Yanayin ƙaddamar da hanyar sadarwa ta TAP ta gama gari
Network Tap yana da lakabi bayyanannu, kamar:

Bayan an haɗa TAP da hanyar sadarwa, duk sauran na'urori da ke kan hanyar sadarwa ba su shafi ba. A gare su, TAP ɗin yana da haske kamar iska, kuma na'urorin sa ido da aka haɗa da TAP suna da haske ga hanyar sadarwa gaba ɗaya.
TAP kamar Port Mirroring ne akan makullin wuta. To me yasa za a tura TAP daban? Bari mu kalli wasu bambance-bambancen da ke tsakanin Network TAP da Network Port Mirroring bi da bi.
Bambanci na 1: TAP na hanyar sadarwa ya fi sauƙin saitawa fiye da mirroring na tashar jiragen ruwa
Dole ne a saita madubin tashar jiragen ruwa a kan maɓallin. Idan ana buƙatar daidaita sa ido, ana buƙatar sake saita maɓallin DUK. Duk da haka, ana buƙatar daidaita TAP ne kawai inda aka buƙata, wanda ba shi da tasiri ga na'urorin sadarwa na yanzu.
Bambanci na 2: TAP na hanyar sadarwa ba ya shafar aikin hanyar sadarwa idan aka kwatanta da madubin tashar jiragen ruwa
Mirroring na tashar jiragen ruwa a kan mashin yana lalata aikin mashin ɗin kuma yana shafar ikon canzawa. Musamman ma, idan mashin ɗin ya haɗu da hanyar sadarwa a jere a matsayin layi, ikon tura dukkan hanyar sadarwar yana da matuƙar tasiri. TAP kayan aiki ne mai zaman kansa kuma baya lalata aikin na'urar saboda mirroring na zirga-zirga. Saboda haka, ba shi da tasiri kan nauyin na'urorin sadarwa da ke akwai, wanda ke da fa'idodi masu yawa fiye da mirroring na tashar jiragen ruwa.
Bambanci na 3: Cibiyar sadarwa ta TAP tana ba da cikakken tsarin zirga-zirga fiye da kwafi na madubin tashar jiragen ruwa
Mirroring na tashar jiragen ruwa ba zai iya tabbatar da cewa za a iya samun dukkan zirga-zirgar ba saboda tashar sauyawa da kanta za ta tace wasu fakitin kuskure ko ƙananan fakiti masu girma. Duk da haka, TAP yana tabbatar da sahihancin bayanai saboda cikakken "kwafi" ne a matakin zahiri.
Bambanci na 4Jinkirin tura TAP ya fi na Port Mirroring ƙanƙanta
A wasu ƙananan maɓallan, madubin tashar jiragen ruwa na iya haifar da jinkiri lokacin kwafi zirga-zirga zuwa tashoshin mirroring, da kuma lokacin kwafi tashoshin jiragen ruwa na 10/100m zuwa tashoshin Giga Ethernet.
Duk da cewa an rubuta wannan sosai, mun yi imanin cewa binciken na ƙarshe guda biyu ba su da wani ƙarfin goyon bayan fasaha.
To, a wane yanayi ne gabaɗaya, muna buƙatar amfani da TAP don rarraba zirga-zirgar hanyar sadarwa? Kawai, idan kuna da waɗannan buƙatu, to Network TAP shine mafi kyawun zaɓinku.
Fasahar TAP ta hanyar sadarwa
Saurari abin da ke sama, ji cewa shunt ɗin hanyar sadarwa ta TAP hakika na'urar sihiri ce, kasuwar da aka saba amfani da ita ta yanzu ta amfani da tsarin gine-gine na kusan nau'ikan uku:

Saboda haka, babban yawan amfani da kuma saurin sadarwa na Network TAP da ake gani a kasuwa yana da dama mai yawa don inganta sassauci a amfani da shi.
