Bayan an haɗa TAP zuwa cibiyar sadarwar, duk sauran na'urorin da ke kan hanyar sadarwar ba su da tasiri.A gare su, TAP a bayyane yake a matsayin iska, kuma na'urorin saka idanu da aka haɗa da TAP suna bayyane ga cibiyar sadarwa gaba ɗaya.
TAP yana kama da Port Mirroring akan maɓalli.Don haka me yasa ake tura TAP daban?Bari mu kalli wasu bambance-bambance tsakanin Network TAP da Network Port Mirroring bi da bi.
Bambanci 1: Network TAP ya fi sauƙi don daidaitawa fiye da madubi na tashar jiragen ruwa
Ana buƙatar saita madubin tashar jiragen ruwa akan maɓalli.Idan ana buƙatar daidaita sa ido, ana buƙatar sake saita maɓalli gabaɗaya.Koyaya, TAP yana buƙatar daidaitawa kawai a inda ya buƙata, wanda ba shi da wani tasiri akan na'urorin cibiyar sadarwa da ake da su.
Bambanci 2: Cibiyar sadarwa TAP baya shafar aikin cibiyar sadarwa dangane da madubin tashar jiragen ruwa
Nuni na tashar tashar jiragen ruwa a kan maɓalli yana lalata aikin maɓalli kuma yana rinjayar ikon sauyawa.Musamman, idan an haɗa maɓalli zuwa cibiyar sadarwa a jeri azaman layin layi, ikon isar da duk hanyar sadarwar yana da matukar tasiri.TAP kayan aiki ne mai zaman kansa kuma baya lalata aikin na'urar saboda madubin zirga-zirga.Sabili da haka, ba shi da tasiri a kan nauyin na'urorin cibiyar sadarwa na yanzu, wanda ke da babban fa'ida akan madubi na tashar jiragen ruwa.
Bambanci 3: Cibiyar sadarwa TAP tana ba da ƙarin cikakken tsarin zirga-zirga fiye da kwafin madubin tashar jiragen ruwa
Madubin tashar jiragen ruwa ba zai iya tabbatar da cewa ana iya samun duk zirga-zirgar ababen hawa ba saboda tashar sauya sheka da kanta za ta tace wasu fakitin kuskure ko ƙananan fakiti masu girma.Duk da haka, TAP yana tabbatar da amincin bayanai saboda yana da cikakkiyar "maimaitawa" a Layer na jiki.
Bambanci 4: Jinkirin isar da TAP ya yi ƙasa da na Port Mirroring
A kan wasu ƙananan ƙananan maɓalli, madubi na tashar jiragen ruwa na iya gabatar da latency lokacin yin kwafin zirga-zirga zuwa tashar jiragen ruwa, da kuma lokacin yin kwafin tashoshin 10/100m zuwa tashoshin Giga Ethernet.
Ko da yake an rubuta wannan a ko'ina, mun yi imanin cewa nazarce-nazarcen biyu na ƙarshe ba su da wani goyan bayan fasaha mai ƙarfi.
Don haka, a wane yanayi na gaba ɗaya, muna buƙatar amfani da TAP don rarraba zirga-zirgar hanyar sadarwa?Kawai, idan kuna da buƙatu masu zuwa, to, Network TAP shine mafi kyawun zaɓinku.
