Ama-TAP (Hlola Amaphuzu Okufinyelela), owaziwa nangokuthi owaziwa nangokuthiUkuphindaphinda Tap, I-Aggregation Tap, Ukuthepha Okusebenzayo, I-Copper Tap, I-Ethernet Tap, I-Optical Tap, I-Physical Tap, njll. Ukuthepha kuyindlela edumile yokuthola idatha yenethiwekhi. Banikeza ukubonakala okuphelele ekugelezeni kwedatha yenethiwekhi futhi baqaphe ngokunembile izingxoxo eziqondiswe kabili ngesivinini somugqa ogcwele, ngaphandle kokulahlekelwa kwephakethe noma ukubambezeleka. Ukuvela kwama-TAP kuye kwaguqula umkhakha wokuqapha nokuqapha kwenethiwekhi, kwashintsha ngokuyisisekelo izindlela zokufinyelela zokuqapha nokuhlaziya izinhlelo nokuhlinzeka ngesixazululo esiphelele nesiguquguqukayo salo lonke uhlelo lokuqapha.
Intuthuko yamanje yobuchwepheshe ikhiqize izinhlobo eziningi zokuthintwa: ompompi abahlanganisa izixhumanisi eziningi, ompompi bokukhiqiza kabusha abahlukanisa ithrafikhi yesixhumanisi sibe izingxenye ezimbalwa, ompompi bokudlula, namaswishi kampompi we-matrix.
Njengamanje, amabhrendi e-Tap adume kakhulu embonini ahlanganisa i-NetTAP ne-Mylinking, phakathi kwayo i-Mylinking iqashelwa njengophawu oluhle kakhulu lwe-Tap kanye ne-NPB embonini yaseShayina, enesabelo semakethe esiphezulu, ukuzinza nokusebenza kahle.
Izinzuzo ze-TAP
1. Thatha u-100% wamaphakethe wedatha ngaphandle kokulahleka kwephakethe.
2. Amaphakethe wedatha angajwayelekile angagadwa, kube lula ukuxazulula inkinga.
3. Izitembu zesikhathi ezinembile, akukho ukubambezeleka kanye nokubeka kabusha isikhathi.
4. Ukufakwa kwesikhathi esisodwa kwenza kube lula ukuxhuma nokuhambisa i-analyzer.
Ukubi kwe-TAP
1. Udinga ukusebenzisa imali eyengeziwe ukuze uthenge i-TAP ehlukanisayo, ebizayo futhi ethatha indawo yokubeka.
2. Isixhumanisi esisodwa kuphela esingabukwa ngesikhathi.
Izicelo Ezijwayelekile ze-TAP
1. Izixhumanisi zezentengiselwano: Lezi zixhumanisi zidinga izikhathi ezimfushane kakhulu zokuxazulula inkinga. Ngokufaka ama-TAP kulezi zixhumanisi, onjiniyela benethiwekhi bangathola ngokushesha futhi baxazulule izinkinga ezingazelelwe.
2. Izixhumanisi eziwumgogodla noma eziwumgogodla. Lezi zinokusetshenziswa okuphezulu komkhawulokudonsa futhi azikwazi ukuphazanyiswa lapho uxhuma noma uhambisa isihlaziyi. I-TAP iqinisekisa ukuthwebula idatha okungu-100% ngaphandle kokulahlekelwa kwephakethe, ihlinzeka isiqinisekiso sokusebenza sokuhlaziya okunembile kwalezi zixhumanisi.
3. I-VoIP ne-QoS: Ikhwalithi ye-VoIP yokuhlolwa kwesevisi idinga izilinganiso ezinembile ze-jitter kanye nokulahlekelwa kwephakethe. Ama-TAP akuqinisekisa ngokugcwele lokhu kuhlolwa, kodwa izimbobo ezinezibuko zingashintsha amanani we-jitter futhi zinikeze amanani angekho ngokoqobo okulahlekelwa kwephakethe.
4. Ukuxazulula inkinga: Qinisekisa ukuthi kutholwa amaphakethe edatha angajwayelekile nayiphutha. Izimbobo ezifakwe esibukweni zizohlunga lawa maphakethe, zivimbele onjiniyela ekunikezeni ulwazi lwedatha olubalulekile noluphelele lokuxazulula inkinga.
5. Uhlelo lokusebenza lwe-IDS: I-IDS incike olwazini lwedatha oluphelele ukuze ihlonze amaphethini okungena, futhi i-TAP inganikeza ukusakazwa kwedatha okuthembekile nokuphelele kusistimu yokuthola ukungena.
6. Iqoqo leseva: I-multi-port splitter ingaxhuma izixhumanisi ezingu-8/12 ngesikhathi esifanayo, inike amandla ukushintsha okukude nokukhululekile, okulungele ukuqapha nokuhlaziya nganoma yisiphi isikhathi.
I-SPAN (Shintsha Ukuhlaziywa Kwembobo)yaziwa nangokuthi i-Mirrored Port noma i-Port Mirror. Ukushintsha okuthuthukile kungakopisha amaphakethe edatha kusuka kusimbobo esisodwa noma ngaphezulu kuya embobeni ekhethiwe, ebizwa ngokuthi "imbobo yesibuko" noma "imbobo okuyiwa kuyo." I-analyzer ingaxhuma embobeni yesibuko ukuze ithole idatha. Nokho, lesi sici singathinta ukusebenza koshintsho futhi sibangele ukulahleka kwephakethe lapho idatha ilayishwa ngokweqile.
Izinzuzo ze-SPAN
1. Ezomnotho, azikho izisetshenziswa ezengeziwe ezidingekayo.
2. Yonke ithrafikhi ku-VLAN ekushintsheni ingagadwa kanyekanye.
3. Isihlaziyi esisodwa singaqapha izixhumanisi eziningi.
Ukungalungi kwe-SPAN
1. Ukufanekisa ithrafikhi kusuka ezimbotsheni eziningi kuya embobeni eyodwa kungabangela ukugcwala kwenqolobane nokulahlekelwa kwephakethe.
2. Amaphakethe ahlelwa kabusha njengoba edlula kunqolobane, okwenza kungenzeki ukunquma ngokunembile izikali zesikhathi ezifana ne-jitter, ukuhlaziya isikhawu sephakethe, nokubambezeleka.
3. Ayikwazi ukuqapha amaphakethe wephutha we-OSI layer 1.2. Izimbobo eziningi ezibonisa idatha zihlunga amaphakethe edatha angajwayelekile, angakwazi ukunikeza imininingwane yedatha enemininingwane newusizo yokuxazulula inkinga.
4. Ngenxa yokuthi ithrafikhi yembobo enezibuko inyusa umthwalo we-CPU weswishi, izobangela ukusebenza kweswishi ukuthi kwehle.
Izicelo Ezijwayelekile ze-SPAN
1. Ukuze uthole izixhumanisi ezinomkhawulokudonsa ophansi namandla amahle okwenza isibuko, ukwenza isibuko samachweba amaningi kungasetshenziselwa ukuhlaziya nokuqapha okuguquguqukayo.
2. Ukuqapha okuthrendayo: Uma ukuqapha okunembayo kungadingeki, izibalo zedatha ezingavamile kuphela ezanele.
3. Ukuhlaziywa kwephrothokholi kanye nesicelo: imininingwane yedatha efanelekile inganikezwa ngendlela elula futhi eyongayo echwebeni lesibuko
4. Ukuqapha okuphelele kwe-VLAN: Ubuchwepheshe bokwenza isibuko esinamachweba amaningi bungasetshenziswa ukuqapha kalula yonke i-VLAN ekushintsheni.
Isingeniso ku-VLAN:
Okokuqala, ake sethule umqondo oyisisekelo wesizinda sokusakaza. Lokhu kubhekisela ebangeni lapho amafreyimu okusakaza (amakheli e-MAC okuyiwa kuwo wonke angu-1) angasakazwa, futhi ngamanye amazwi, ububanzi lapho ukuxhumana okuqondile kungenzeka khona. Uma sikhuluma ngokuqinile, akuwona kuphela amafreyimu okusakaza, kodwa namafreyimu asakazwa nge-multicast namafreyimu angaziwa angahamba ngokukhululeka ngaphakathi kwesizinda sokusakaza esifanayo.
Ekuqaleni, iswishi Yesendlalelo 2 yayingakwazi ukusungula isizinda esisodwa sokusakaza. Kuswishi Yesendlalelo 2 ngaphandle kwanoma yimaphi ama-VLAN amisiwe, noma yiluphi uhlaka lokusakaza luzodluliselwa kuzo zonke izimbobo ngaphandle kwembobo eyamukelayo (egcwele izikhukhula). Nokho, ukusebenzisa ama-VLAN kuvumela inethiwekhi ukuthi ihlukaniswe izizinda zokusakaza eziningi. Ama-VLAN ubuchwepheshe obusetshenziswa ukuhlukanisa izizinda zokusakaza kumaswishi e-Layer 2. Ngokusebenzisa ama-VLAN, singakwazi ukuklama ngokukhululekile ukwakheka kwezizinda zokusakaza, sikhulise ukuguquguquka komklamo wenethiwekhi.
