Le khasiBroker ye-Network Packet(NPB), okubandakanya i-1G NPB esetshenziswa kakhulu, 10G NPB, 25G NPB, 40G NPB, I-100G NPB, ne-400G NPB, kanyeI-Port Yokufinyelela Kwenethiwekhi Yenethiwekhi (Thepha), iyithuluzi le-Hardware elixhuma ngqo kwikhebula lenethiwekhi bese lithumela ucezu lokuxhumana kwenethiwekhi kwamanye amadivayisi.
Abathengisi be-Network Packat bavame ukusetshenziswa ezinhlelweni zokutholwa kwe-Network Antring (IDS), abathola ama-network, kanye namaphrofayli. Iseshini yokubukisa ye-port. Kwindlela yokujaha, isixhumanisi se-UTP esibhekwe (isixhumanisi esingahleliwe) sihlukaniswe izingxenye ezimbili ngocingo olubhekisisa khona. Idatha eshisiwe ixhunyiwe kusibonisi sokuqoqa ukuqoqa idatha yohlelo lokuhlola ulwazi lwe-Intanethi.
Ngabe i-The Network Packet Broker (NPB) ikwenzela ini?
Izici ezibalulekile:
1. Izimele
Kuyinto ende yehadiwe futhi ayithinti umthwalo wamadivayisi akhona wenethiwekhi, anezinzuzo ezinhle kakhulu ngaphezulu kokuthola izibuko ethekwini.
Kuyithuluzi elikulayini, okusho nje ukuthi lidinga ukubhebhana kwinethiwekhi. Kodwa-ke, lokhu kubuye kube nokungabi nabikwa kokwethula iphuzu lokuhluleka, futhi ngoba kuyithuluzi eliku-inthanethi, inethiwekhi yamanje idinga ukuphazanyiswa ngesikhathi sokufakwa, kuye ngokuthi kuthunyelwe kuphi.
2. Esobala
Ukusobala kusho i-pointer kwinethiwekhi yamanje. Ngemuva kokufinyelela inethiwekhi ye-shunt, akunamthelela kuwo wonke amadivayisi kunethiwekhi yamanje, futhi kuyabonakala ngokuphelele kubo. Vele, lokhu kufaka phakathi ithrafikhi ethunyelwe yinethiwekhi ye-shunt kudivayisi yokuqapha, nayo ebonakalayo kwinethiwekhi.
Umgomo Wokusebenza:
Ithrafikhi ebhekisisa (ukusabalalisa) ngokususelwa kwidatha yokufaka, ukuphindaphinda, ukuqoqa, ukuhlunga, ukuguqulwa kwedatha ye-10G POS ngokuphuma kwe-protocol letshini, noma okuphumayo kwe-IP wonke amaphakethe avela ku-interface yomsebenzisi efanayo.
Izici ezisebenzayo:
1. Ukuguqulwa kwe-Protocol
Izindawo zokuxhumana ze-Intanethi ezijwayelekile ezisetshenziswa yi-ISPS zifaka ama-ISPs zifaka i-40G POS, 10G POS / LAN / LAN, ngenkathi idatha ethola indawo esetshenziswa yi-GEP kanye ne-10GE LAN PORFACS. Ngakho-ke, ukuguqulwa kwe-protocol kuvame okukhulunywa ngawo ekuxhumaneni kwe-Intanethi ikakhulukazi kubhekisa ekuguqukeni phakathi kwe-40g POS, i-10G POS, kanye ne-2.5g POTRansfer phakathi kwe-10ge wan kanye ne-ge.
2. Ukuqoqwa kwedatha nokusatshalaliswa.
Izicelo eziningi zokuqoqa idatha ngokuyisisekelo zikhipha ithrafikhi abayikhathalelayo futhi balahle ithrafikhi abangayikhathaleli. Ithrafikhi yedatha yekheli elithile le-IP, i-Protocol, kanye nePort kukhishwe nge-Tuple-Tuple (Ikheli le-IP le-IP, ikheli le-IP, indawo ethekwini, i-Portocol). Lapho kukhishwa, umthombo ofanayo, indawo efanayo nokukhishwa kwebhalansi yomthwalo kuqinisekiswe ngokuya nge-hashi algorithm ethile.
3. Isici sokuhlunga ikhodi
Ngokuqoqwa kwethrafikhi ye-P2P, uhlelo lokusebenza lungagxila kuphela kwethrafikhi ethile, efana nokusakazwa kwabezindaba i-PPStream, BT, Thunderbolt, kanye namagama ajwayelekile ajwayelekile ku-HTTP afana nokuthumela, njll. I-Diverter isekela ikhodi yesikhundla esimisiwe sokuhlunga nokuhlunga kwekhodi yesici esintantayo. Ikhodi yesici esintantayo iyi-offset ebekiwe ngesisekelo sekhodi yesici sendawo engaguquki. Ilungele izinhlelo zokusebenza ezicacisa ikhodi yesici ukuthi ihlungwe, kepha ungacacisi indawo ethile yekhodi yesici.
4. Ukuphathwa Kweseshini
Khomba ithrafikhi yeseshini futhi ngeguquguqukayo ukulungiselela i-Sex Prepling NEVER (N = 1 kuye ku-1024). Lokho wukuthi, amaphakethe okuqala we-N akhishwe futhi athunyelwa ohlelweni lokuhlaziya uhlelo lokusebenza lwasemuva, kanye namaphakethe ngemuva kokulahlwa, ukulondolozwa kwezinsizakusebenza ngeplatifomu ehlaziywe yohlelo lokusebenza lwe-Downstream. Ngokuvamile, lapho usebenzisa ama-ID ukubheka izehlakalo, awudingi ukucubungula wonke amaphakethe esikhathi sonke; Esikhundleni salokho, udinga nje ukukhipha amaphakethe okuqala we-N weseshini ngalinye ukuqedela ukuhlaziya nokuqapha komcimbi.
I-5. Idatha yokubuka kanye nokuphindaphindwa
I-splitter ingabona izibuko nokuphindaphindwa kwemininingwane esibonakalayo sokuphuma, esiqinisekisa ukufinyelela kwedatha kwezinhlelo zesicelo eziningi.
6. I-3G yenethiwekhi yokutholwa kwedatha kanye nokuthumela phambili
Ukuqoqwa kwedatha nokusatshalaliswa kumanethiwekhi we-3G ahlukile ezindleleni zokuhlaziywa kwenethiwekhi yezentengo. Amaphakethe kumanethiwekhi we-3G adluliselwa kwizixhumanisi ezi-Backbone ngokusebenzisa izingqimba eziningi ze-Encapsettion. I-Packet Hered and Encopsetion formation ihlukile kulawo amaphakethe kumanethiwekhi afanayo. I-splitter ingahlonza ngokunembile futhi icubungule amaphrothokhokholi wemihubhe njengama-GTP namaphakethe we-GRE, amaphakethe we-multilayer MPL, namaphakethe we-VLAN. Ingakhipha amaphakethe okusayina ama-IUps, amaphakethe we-GTP ama-PASTION, namaphakethe we-radius kumachweba acacisiwe asuselwa kwizici zephakethe. Ngaphezu kwalokho, ingahlukanisa amaphakethe ngokuya ngekheli le-IP elingaphakathi. Ukuxhaswa kwamaphakeji we-Overlands (MTU> 1522 arte) ukucubungula, kungakubona kahle ukuqoqwa kwedatha yenethiwekhi ye-3G kanye nesicelo se-shunt.
Izidingo zesici:
- Usekela ukusatshalaliswa kwethrafikhi nge-L2-L7 Protocol Protocol.
- Usekela ukuhlunga okungu-5-tuple ngekheli le-IP le-IP eliqondile, ikheli le-IP le-IP, i-Source Port, indawo oyiqophayo, ne-protocol kanye ne-protocol ne-mask.
- Usekela okukhishwayo kokukhishwa komthwalo wokulinganisa nokukhipha i-homology kanye ne-homology.
- Usekela ukuhlunga nokudluliselwa ngemicu yezinhlamvu.
- Usekela ukuphathwa kweseshini. Dlulisela amaphakethe okuqala we-N yeseshini ngalinye. Inani le-n lingacaciswa.
- Usekela abasebenzisi abaningi. Amaphakethe wedatha ahambelana nomthetho ofanayo anganikezwa kowesithathu ngasikhathi sinye, noma imininingwane esibonakalayo sokuphuma ingabukwa futhi iphindwaphindwa, iqinisekisa ukufinyelela idatha kwezinhlelo zesicelo eziningi.
Isixazululo Sezixazululo Zomkhakha Wezezimali Isixazululo
Ngokuthuthuka okusheshayo kobuchwepheshe bolwazi lomhlaba jikelele kanye nokujula kwe-informatization, isilinganiso senethiwekhi yebhizinisi sinwetshwe kancane kancane, futhi ukuthembela kwezimboni ezahlukahlukene ohlelweni lwemininingwane sekuyenyuka kakhulu. Ngasikhathi sinye, inethiwekhi yamabhizinisi yokuhlaselwa kwangaphakathi nangaphandle, ukungahambi kahle, kanye nezinsongo zokuphepha zolwazi nazo zikhula, zonke izinhlobo zokuvikelwa kwebhizinisi, kuzokwazi ukuchitha indawo yenethiwekhi, okusobala, okuhlongozwayo kwe-topology kanye nenkinga yokuqapha ukusebenza okuphansi okusebenzayo Ukusebenza kahle, ukutshalwa kwemali okuphezulu, imali engenayo, ukugcinwa kwesikhathi kanye nobunzima bokuphatha, izinsiza zedatha kunzima ukuzilawula.
