Lapho uhlelo lokutholwa kwe-Inclusion (ID) luthunyelwa, itheku le-Mirroring ekushintsheni kwesikhungo semininingwane sephathi kontanga alwanele (ngokwesibonelo, ichweba elilodwa le-Mirroring livunyelwe, futhi i-Mirroring Port inezinto eziningi).
Ngalesi sikhathi, lapho singangezi amachweba amaningi wesibuko, singasebenzisa ukuphindaphinda kwenethiwekhi, ukuhlanganiswa kanye nokudlulisela idivaysi ukusabalalisa inani elifanayo ledatha yezibuko kudivayisi yethu.
Yini i-tap yenethiwekhi?
Mhlawumbe uqale wezwa igama elithi Thinta Shintsha. Thepha (indawo yokufinyelela esibulalayo), eyaziwa nangokuthi i-NPB (inethiwekhi yephakethe lepakethi), noma i-Tap Aggregator?
Umsebenzi oyisisekelo weTampu ukusetha phakathi kwetheku le-Mirroring kwinethiwekhi yokukhiqiza kanye neqoqo ledivayisi yokuhlaziya. Impompi iqoqa traffic ezibunjiwe noma ezihlukanisiwe kusuka kumadivayisi wenethiwekhi eyodwa noma ngaphezulu futhi isabalalisa ithrafikhi kwimishini eyodwa noma eziningi zokuhlaziya idatha.
Izimo ezijwayelekile zokuthepha zenethiwekhi
I-Network Tap inamalebula asobala, njenge:
Hardware ezimele
I-Tap iyingxenye ehlukile ye-hardware engathinti umthwalo kumadivayisi akhona wenethiwekhi, okungomunye wezinzuzo ezingaphezu kwezibuko ethekwini.
Shintsha?
Thepha ngenethiwekhi?
Inethiwekhi esobala
Ngemuva kokuthi okokuthepha kuxhunyiwe kwinethiwekhi, wonke amanye amadivaysi kunethiwekhi awathinteki. Kubo, ithempeli lisobala njengomoya, futhi amadivayisi wokuqapha axhunyiwe empompini abonakala obala kwinethiwekhi ephelele.
Thepha kufana nokubukwa kwetheku ku-switch. Ngakho-ke kungani ufaka empompini ehlukile? Ake sibheke eminye umehluko phakathi kokuthepha kwenethiwekhi kanye nenethiwekhi yenethiwekhi nayo.
Umehluko 1: I-Test Network kulula ukumisa ukwedlula izibuko ezichwebeni
I-Port Mirroring Izidingo Zokuhlelwa Ekushintsheni. Uma ukuqapha kudinga ukulungiswa, ukushintshwa kudinga ukulungiswa kabusha konke. Kodwa-ke, ithempeli lidinga kuphela ukulungiswa lapho ulucelile, olungenawo umthelela kumadivayisi wenethiwekhi akhona.
Umehluko 2: I-Network Tap ayithinti ukusebenza kwenethiwekhi okuhlobene nokubukwa kwe-portroring
I-Port Izibuko ekushintsheni kwehla ukusebenza kwe-switch futhi kuthinta amandla okushintsha. Ikakhulu, uma ukushintshwa kuxhunyiwe kwinethiwekhi ochungechungeni njengo-inline, amandla okudlulisa kuwo wonke amanethiwekhi athinteka kakhulu. I-TAP iyi-Hardware ezimele futhi ayilimazi ukusebenza kwedivaysi ngenxa yezibuko zethrafikhi. Ngakho-ke, akunamthelela emthwalweni wamadivayisi akhona wenethiwekhi, anezinzuzo ezinhle kakhulu ngaphezulu kokuzibuka kwetheku.
Umehluko 3: I-Network Tap inikezela ngenqubo ephelele yethrafikhi kunesiphikiso se-portroring replication
Ukubukwa kwe-portroring akunakuqinisekisa ukuthi yonke ithrafikhi ingatholakala ngoba itheku lokushintsha uqobo lizohlunga amaphakethe athile wephutha noma amaphakethe asayizi amancane kakhulu. Kodwa-ke, impompi iqinisekisa ubuqotho bedatha ngoba kungukuthi "ukuphindaphindwa" okuphelele kungqimba lomzimba.
Umehluko 4: Ukubambezeleka kokudlulisela kokuthepha kuncane kunalokho kwe-portroring
Kwezinye izinguquko eziphansi, izibuko ze-port zingangenisa i-latency lapho ukopisha ithrafikhi ukuze ubonise amachweba okuthola amaphuzu, kanye nalapho ukopisha amachweba ayi-10/100 omsePiga Ethernet.
Yize lokhu kubhalwe kabanzi, sikholwa ukuthi ukuhlaziya okubili kokugcina kuntula ukwesekwa kwezobuchwepheshe okuqinile.
Ngakho-ke, kuliphi isimo esijwayelekile, kudingeka sisebenzise i-Thepha ukuze kusatshalaliswe ithrafikhi yenethiwekhi? Simply, uma unezidingo ezilandelayo, i-Tap yenethiwekhi iyisinqumo sakho esihle kakhulu.
Technologies Yenethiwekhi
Lalela lokhu okungenhla, zizwe i-Tap Network Shunt ngempela idivaysi yemilingo, imakethe yamanje yethempent evamile ye-shunt esebenzisa ukwakhiwa okungaphansi kwezigaba ezintathu:
I-FPGA
- Ukusebenza okuphezulu
- Kunzima ukuthuthukisa
- Izindleko eziphakeme
Ama-mips
- Iguqukayo futhi elula
- Ubunzima bokuthuthukiswa ngokulinganiselayo
- Abathengisi be-Maintream RMI neCavium Bethumba Ukuthuthukiswa Futhi Yehlulekile Kamuva
Amasondo
- Ukusebenza okuphezulu
- Ukuthuthukiswa komsebenzi wokunwebeka kunzima, ikakhulukazi ngenxa yokulinganiselwa kwe-chip uqobo
- Isimo esibonakalayo nokucaciswa kukhawulelwe yi-chip uqobo, okuholela ekusebenzeni kahle kokunwetshwa
Ngakho-ke, ubuningi obuphezulu kanye ne-high speed network tampo ebonwe emakethe inendawo eningi yokuthuthuka ekuguqulekeni kwezimo ezisebenzayo. Thepha inethiwekhi shunters isetshenziselwa ukuguqulwa kwe-protocol, ukuqoqwa kwedatha, ukunyakazisa idatha, ukuboniswa kwedatha, nokuhlunga kwethrafikhi. Izinhlobo ezijwayelekile zePort zifaka i-100G, 40G, 10G, 2,5G POS, GE, njll ngenxa yokuhoxiswa kancane kwemikhiqizo ye-SDH, ama-shunters wenethiwekhi yamanje asetshenziswa kakhulu emvelweni yenethiwekhi ye-Ethernet.
