Umthengisi Wephakethe Lenethiwekhi(NPB) iyidivayisi yenethiwekhi efana nokushintsha ehluka ngobukhulu kusukela kumadivayisi aphathekayo kuya kumacala eyunithi angu-1U kanye no-2U kuya kumacala amakhulu kanye nezinhlelo zamabhodi. Ngokungafani nokushintsha, i-NPB ayishintshi ithrafikhi egeleza kuyo nganoma iyiphi indlela ngaphandle kokuthi iqondiswe ngokucacile. Ihlala phakathi kwama-taps nama-port e-SPAN, ifinyelela idatha yenethiwekhi kanye namathuluzi okuphepha nokuqapha ayinkimbinkimbi avame ukuhlala ezikhungweni zedatha. I-NPB ingathola ithrafikhi ku-interface eyodwa noma ngaphezulu, yenze imisebenzi ethile echazwe kusengaphambili kuleyo thrafikhi, bese iyikhipha ku-interface eyodwa noma ngaphezulu ukuze ihlaziye okuqukethwe okuhlobene nokusebenza kwenethiwekhi, ukuphepha kwenethiwekhi kanye nobuhlakani bezingozi.
Ngaphandle kwe-Network Packet Broker
Yiziphi izimo ezidinga i-Network Packet Broker?
Okokuqala, kunezidingo eziningi zethrafikhi zamaphoyinti afanayo okuthwebula ithrafikhi. Ukuthepha okuningi kwengeza amaphuzu amaningi okwehluleka. Ukulinganisa okuningi (i-SPAN) kuthatha amachweba amaningi okulinganisa, okuthinta ukusebenza kwedivayisi.
Okwesibili, idivayisi yokuphepha efanayo noma uhlelo lokuhlaziya ithrafikhi kudingeka luqoqe ithrafikhi yamaphuzu amaningi okuqoqa, kodwa imbobo yedivayisi inqunyelwe futhi ayikwazi ukwamukela ithrafikhi yamaphuzu amaningi okuqoqa ngesikhathi esisodwa.
Nazi ezinye izinzuzo zokusebenzisa i-Network Packet Broker kunethiwekhi yakho:
- Hlunga futhi uhlukanise ithrafikhi engavumelekile ukuze uthuthukise ukusetshenziswa kwamadivayisi okuphepha.
- Isekela izindlela eziningi zokuqoqa ithrafikhi, okuvumela ukuthunyelwa okuguquguqukayo.
- Isekela ukuhlukaniswa kwe-tunnel ukuze ihlangabezane nezidingo zokuhlaziya ithrafikhi yenethiwekhi ebonakalayo.
- Ukuhlangabezana nezidingo zokususa uzwela ngasese, wonge imishini ekhethekile yokususa uzwela kanye nezindleko;
- Bala ukubambezeleka kwenethiwekhi ngokusekelwe ezitembu zesikhathi zephakethe ledatha elifanayo ezindaweni ezahlukene zokuqoqa.
Nomthengisi Wephakethe Lenethiwekhi
Umthengisi Wephakethe Lenethiwekhi - Lungiselela Ukusebenza Kahle Kwamathuluzi Akho:
1- I-Network Packet Broker ikusiza ukuthi usebenzise ngokugcwele amadivayisi okuqapha kanye nokuphepha. Ake sicabangele ezinye zezimo ezingaba khona ongase uhlangane nazo usebenzisa la mathuluzi, lapho amadivayisi akho amaningi okuqapha/okuphepha angase achithe amandla okucubungula ithrafikhi angahlobene naleyo divayisi. Ekugcineni, idivayisi ifinyelela umkhawulo wayo, iphatha ithrafikhi ewusizo nengasizi ngalutho. Kuleli qophelo, umthengisi wamathuluzi ngokuqinisekile uzokujabulela ukukunikeza umkhiqizo onamandla ohlukile onamandla okucubungula okwengeziwe ukuxazulula inkinga yakho... Noma kunjalo, kuzohlala kuwukuchitha isikhathi, kanye nezindleko ezengeziwe. Uma singasusa yonke ithrafikhi engenangqondo ngaphambi kokuba ithuluzi lifike, kuzokwenzekani?
2- Futhi, ake sithi idivayisi ibheka ulwazi lwekhanda kuphela ngethrafikhi eyitholayo. Ukusika amaphakethe ukuze kususwe umthwalo okhokhelwayo, bese kuthunyelwa ulwazi lwekhanda kuphela, kunganciphisa kakhulu umthwalo wethrafikhi kuthuluzi; Pho kungani kungenjalo? I-Network Packet Broker (NPB) ingakwenza lokhu. Lokhu kwandisa impilo yamathuluzi akhona futhi kunciphisa isidingo sokuthuthukiswa njalo.
3- Ungase uzithole uphelelwa yizindawo zokusebenzelana ezitholakalayo kumadivayisi asenesikhala esiningi samahhala. Indawo yokusebenzelana kungenzeka ingadluliseli eduze kwethrafikhi yayo etholakalayo. Ukuhlanganiswa kwe-NPB kuzoxazulula le nkinga. Ngokuhlanganisa ukugeleza kwedatha kudivayisi ku-NPB, ungasebenzisa indawo yokusebenzelana ngayinye enikezwe yidivayisi, uthuthukise ukusetshenziswa kwe-bandwidth kanye nokukhulula izindawo zokusebenzelana.
4- Ngendlela efanayo, ingqalasizinda yakho yenethiwekhi ithuthelwe kumaGigabytes ayi-10 futhi idivayisi yakho ine-gigabyte eyodwa kuphela yezixhumi. Idivayisi ingase isakwazi ukuphatha kalula ithrafikhi kulezo zixhumanisi, kodwa ayikwazi ukuxoxisana ngesivinini sezixhumanisi nhlobo. Kulesi simo, i-NPB ingasebenza ngempumelelo njengesiguquli sejubane futhi idlulisele ithrafikhi kuthuluzi. Uma i-bandwidth inqunyelwe, i-NPB ingaphinde yandise impilo yayo ngokulahla ithrafikhi engafanele, yenza ukusika amaphakethe, kanye nokulinganisa ithrafikhi esele kuzixhumi ezitholakalayo zethuluzi.
5- Ngokufanayo, i-NPB ingasebenza njengesiguquli semidiya lapho yenza le misebenzi. Uma idivayisi inesixhumi sekhebula lethusi kuphela, kodwa idinga ukuphatha ithrafikhi evela kusixhumanisi se-fiber optic, i-NPB ingasebenza futhi njengomlamuleli ukuze ithole ithrafikhi kudivayisi futhi.
