Broker ye-Network Packet(NPB) iyindlela yokushintsha njengedivaysi yenethiwekhi esukela ngosayizi kusuka kumadivayisi aphathekayo kuya kumacala aphathekayo kuya ku-1u kanye no-2u unit amacala ezimweni ezinkulu nasezinhlelweni zamabhodi. Ngokungafani nokushintshwa, i-NPB ayishintshi ithrafikhi egeleza ngayo nganoma iyiphi indlela ngaphandle kokuthi ifundiswe ngokucacile. Ihlala phakathi kweTaps nama-Span Ports, idatha yenethiwekhi yokufinyelela kanye nokuphepha okuyinkimbinkimbi namathuluzi okuqapha okuvame ukuhlala ezikhungweni zedatha. I-NPB ingathola ithrafikhi endaweni eyodwa noma ngaphezulu, yenza eminye imisebenzi echazwe ngaphambilini kulowo mgwaqo, bese uyikhipha endaweni eyodwa noma ngaphezulu yokuhlaziya okuqukethwe okuhlobene nokusebenza kwenethiwekhi, ukuphepha kwenethiwekhi kanye nobuhlakani obusongele.
Ngaphandle kwe-Network Packet Broker
Yiziphi izimo ezidinga i-Network Packet Broker?
Okokuqala, kunezidingo eziningi zethrafikhi zamaphoyinti afanayo wokuthwebula amathrafikhi. Ompompi abaningi bangeza amaphuzu amaningi okuhluleka. I-Multiple Milroring (SPAN) ihlala amachweba amaningi okuthola izibuko, okuthinta ukusebenza kwensiza.
Okwesibili, idivaysi efanayo yezokuphepha noma uhlelo lokuhlaziywa kwezimoto ludinga ukuqoqa ithrafikhi yamaphoyinti okuqoqa amaningi, kepha itheku ledivayisi lilinganiselwe futhi alikwazi ukuthola ithrafikhi yamaphoyinti okuqoqa amaningi ngasikhathi sinye.
Nazi ezinye izinzuzo zokusebenzisa i-Network Packet Broker yenethiwekhi yakho:
- Hlunga futhi unikezele ithrafikhi engavumelekile yokuthuthukisa ukusetshenziswa kwamadivayisi wokuphepha.
- Usekela izindlela eziningi zokuqoqwa kwethrafikhi, okwenza ukuhanjiswa okuguquguqukayo okuvumelayo.
- Usekela ukugunyazwa komhubhe ukufeza izidingo zokuhlaziya ithrafikhi yenethiwekhi ebonakalayo.
- Hlangana nezidingo zokuxhashazwa okuyimfihlo, gcina imishini ekhethekile yokuhlaziya nezindleko;
- Bala ukubambezeleka kwenethiwekhi ngokuya ngezitembu zesikhathi sepakethe ledatha elifanayo ezindaweni zokuqoqa ezihlukile.
Nge-Network Packet Broker
I-Network Packet Broker - Lungiselela ukusebenza kahle kwamathuluzi:
Umthengisi wenethiwekhi we-1- Iphakethe lenethiwekhi likusiza ukuthi usebenzise ngokugcwele amadivaysi okuphepha nawokuphepha. Ake sicabangele ezinye zezimo ezingaba khona ongase uhlangane nazo usebenzisa la mathuluzi, lapho amadivaysi akho amaningi okuqapha / wokuphepha angahle achithe amandla okusebenza kwethrafikhi engahlobene naleya divayisi. Ekugcineni, idivaysi ifinyelela umkhawulo wayo, iphatha ithrafikhi ewusizo futhi ewusizo. Ngalesi sikhathi, iThuluzi Lomthengisi lizojabula ngokuqinisekile ukukunikeza umkhiqizo onamandla okunamandla ngisho namandla okwengeziwe wokuxazulula inkinga yakho ... Noma kunjalo, kuzoba ukuchitha isikhathi, kanye nezindleko ezengeziwe. Ukube besingasusa yonke ithrafikhi engenzi mqondo kuyo ngaphambi kokuthi ithuluzi lifike, kwenzekani?
2- Futhi, cabanga ngokuthi idivaysi ibheka kuphela imininingwane yeheda yethrafikhi etholayo. Amaphakethe okusika ukuze asuse i-payload, bese udlulisela imininingwane yeheda kuphela, anganciphisa kakhulu umthwalo wethrafikhi ethubeni; Ngakho-ke kungani kungenjalo? I-Network Packet Broker (NPB) ingakwenza lokhu. Lokhu kunweba impilo yamathuluzi akhona futhi kunciphisa isidingo sokuthuthuka njalo.
3- Ungazithola usuphela ezindaweni ezitholakalayo kumadivayisi asenesikhala esiningi samahhala. I-interface kungenzeka ingadlulisi eduze kwethrafikhi yayo etholakalayo. Ukuhlanganiswa kwe-NPB kuzoxazulula le nkinga. Ngokufaka imali ehlanganisiwe ukugeleza kudivayisi ku-NPB, ungathola inzuzo ngayinye ebonakalayo enikezwe yidivayisi, ukwenza umsebenzi we-bandwidth kanye nezindawo zokugibela.
4- Ngenothi elifanayo, ingqalasizinda yakho yenethiwekhi ifudukelwe kuya kuma-Gigabytes ayi-10 futhi idivaysi yakho ine-1 gigabyte kuphela yezindawo zokuxhumana. Idivayisi isengakwazi ukuphatha kalula ithrafikhi kulezo zixhumanisi, kepha ayinakuxoxisana ngejubane lezixhumanisi nhlobo. Kulokhu, i-NPB ingasebenza ngempumelelo njengesiguquli sejubane futhi iphasise ithrafikhi ithuluzi. Uma i-bandwidth limited, i-NPB nayo ingaphinde iphinde iphinde ilahle yonke ithrafikhi engafanele, yenza ama-packet slicing, bese ulayisha ngokulinganisa ithrafikhi etholakalayo endaweni etholakalayo yamathuluzi.
5- Ngokufanayo, i-NPB ingasebenza njengesiguquli semidiya lapho yenza le misebenzi. Uma idivaysi ine-interface yentambo yethusi kuphela, kepha idinga ukuphatha ithrafikhi kusuka kusixhumanisi se-fiber optic, i-NPB ingaphinde isebenze njengommeli ukuze uthole ithrafikhi kudivayisi futhi.
