Esimeni sanamuhla sedijithali, lapho ukufinyelela ku-inthanethi kuyinto yonke indawo, kubalulekile ukuthi kube nezinyathelo zokuphepha eziqinile ukuze uvikele abasebenzisi ekufinyeleleni amawebhusayithi okungenzeka ayingozi noma angalungile. Isixazululo esisodwa esisebenzayo ukuqaliswa kwe-Network Packet Broker (NPB) ukuqapha nokulawula ithrafikhi yenethiwekhi.
Ake sidlule esimweni ukuze siqonde ukuthi i-NPB ingasetshenziswa kanjani ngale njongo:
1- Umsebenzisi ufinyelela iwebhusayithi: Umsebenzisi uzama ukufinyelela iwebhusayithi kusuka kudivayisi yakhe.
2- Amaphakethe adlulayo aphindwa yi-aI-Passive Tap: Njengoba isicelo somsebenzisi sidlula kunethiwekhi, i-Passive Tap iphinda amaphakethe, ivumela i-NPB ukuthi ihlaziye ithrafikhi ngaphandle kokuphazamisa ukuxhumana kwasekuqaleni.
3- I-Network Packet Broker idlulisela ithrafikhi elandelayo Kuseva Yenqubomgomo:
- I-HTTP GET: I-NPB ihlonza isicelo se-HTTP GET futhi isidlulisela Kuseva Yenqubomgomo ukuze iphinde ihlolwe.
- Iklayenti le-HTTPS TLS Sawubona: Ngethrafikhi ye-HTTPS, i-NPB ithwebula iphakethe le-TLS Client Hello bese ilithumela Kuseva Yenqubomgomo ukuze inqume iwebhusayithi okuyiwa kuyo.
4- Iseva Yenqubomgomo ihlola ukuthi ingabe iwebhusayithi efinyelelwe isohlwini oluvinjelwe: Iseva Yenqubomgomo, ifakwe imininingwane egciniwe yamawebhusayithi ayingozi noma angafuneki, ihlola ukuthi ingabe iwebhusayithi eceliwe isohlwini oluvinjelwe.
5- Uma iwebhusayithi isohlwini oluvinjelwe, Iseva Yepholisi ithumela iphakethe Lokusetha Kabusha le-TCP:
- Kumsebenzisi: Iseva Yenqubomgomo ithumela iphakethe Lokusetha Kabusha le-TCP elinomthombo we-IP wewebhusayithi kanye ne-IP yendawo yomsebenzisi, inqamule ngempumelelo ukuxhumeka komsebenzisi kuwebhusayithi evinjelwe.
- Kuwebhusayithi: Iseva Yepholisi futhi ithumela iphakethe Lokusetha Kabusha le-TCP elinomthombo we-IP womsebenzisi kanye ne-IP yendawo okuyiwa kuyo yewebhusayithi, inqamule ukuxhumeka komunye umkhawulo.
6- Ukuqondisa kabusha kwe-HTTP (uma ithrafikhi kuyi-HTTP): Uma isicelo somsebenzisi senziwe nge-HTTP, Iseva Yenqubomgomo iphinda ithumele ukuqondisa kabusha kwe-HTTP kumsebenzisi, ibaqondise kabusha kuwebhusayithi ephephile, ehlukile.
Ngokusebenzisa lesi sixazululo kusetshenziswa i-Network Packet Broker kanye Neseva Yenqubomgomo, izinhlangano zingaqapha ngempumelelo futhi zilawule ukufinyelela kwabasebenzisi kumawebhusayithi avinjelwe, zivikele inethiwekhi yabo kanye nabasebenzisi ekulimaleni okungaba khona.
I-Network Packet Broker (NPB)iletha ithrafikhi evela emithonjeni eminingi ukuze kuhlungwe okwengeziwe ukuze kusizwe ukulinganisela ukugcwala kwethrafikhi, ukusikwa kwethrafikhi, namandla okufihla. Ama-NPB enza kube lula ukuhlanganiswa kwethrafikhi yenethiwekhi evela emithonjeni eyahlukene, okuhlanganisa amarutha, amaswishi, nama-firewall. Le nqubo yokuhlanganisa idala ukusakaza okukodwa, okwenza kube lula ukuhlaziya nokuqapha imisebenzi yenethiwekhi. Lawa madivayisi aqhubeka nokwenza lula ukuhlunga kwethrafikhi yenethiwekhi eqondisiwe, okuvumela izinhlangano ukuthi zigxile kudatha efanelekile yakho kokubili ukuhlaziya nezinjongo zokuphepha.
Ngokungeziwe emandleni abo okuhlanganisa nawokuhlunga, ama-NPB abonisa ukusatshalaliswa kwethrafikhi yenethiwekhi ehlakaniphile kuwo wonke amathuluzi amaningi okuqapha nokuphepha. Lokhu kuqinisekisa ukuthi ithuluzi ngalinye lithola idatha edingekayo ngaphandle kokuyigcwalisa ngolwazi olungaphandle. Ukuzivumelanisa nezimo kwama-NPB kudlulela ekwandiseni ukugeleza kwethrafikhi yenethiwekhi, ukuhambisana namakhono ayingqayizivele namandla wamathuluzi ahlukene wokuqapha nokuphepha. Lokhu kulungiselelwa kukhuthaza ukusetshenziswa kahle kwezinsiza kuyo yonke ingqalasizinda yenethiwekhi.
Izinzuzo ezibalulekile ze-Network Packet Broker zale ndlela zihlanganisa:
- Ukubonakala okuphelele: Ikhono le-NPB lokuphindaphinda ithrafikhi yenethiwekhi livumela ukubuka okuphelele kwakho konke ukuxhumana, okufaka kokubili ithrafikhi ye-HTTP ne-HTTPS.
- Ukulawulwa kwe-Granular: Amandla Eseva Yenqubomgomo yokugcina uhlu oluvinjiwe futhi enze izenzo eziqondiwe, ezifana nokuthumela amaphakethe Wokusetha Kabusha i-TCP kanye nokuqondisa kabusha kwe-HTTP, kunikeza ukulawula okuncane kokufinyelela komsebenzisi kumawebhusayithi angafuneki.
- Scalability: Ukuphatha kahle kwe-NPB kwethrafikhi yenethiwekhi kuqinisekisa ukuthi lesi sixazululo sokuvikeleka singakalwa ukuze kuhlangatshezwane nezidingo ezikhulayo zabasebenzisi kanye nobunkimbinkimbi benethiwekhi.
Ngokusebenzisa amandla E-Network Packet Broker kanye Neseva Yenqubomgomo, izinhlangano zingathuthukisa ukuma kwazo kwenethiwekhi futhi zivikele abasebenzisi bazo ezingozini ezihlobene nokufinyelela amawebhusayithi avinjelwe.
