Yiziphi izinkinga ezijwayelekile ezingaxazululwa yi-Network Packet Broker?
Siwamboze la makhono futhi, kule nqubo, ezinye zezicelo ze-NPB ezingaba khona. Manje ake sigxile emaphoyinti ajwayelekile obuhlungu amakheli we-NPB.
Udinga i-Network Packet Broker lapho ukufinyelela kwakho kwenethiwekhi kukhawulelwe khona:
Inselelo yokuqala ye-Network Packet Broker ikhawulelwe ukufinyelela. Ngamanye amagama, ukukopisha / ukudlulisa ithrafikhi yenethiwekhi kuwo wonke amathuluzi okuphepha kanye nokuqapha njengezidingo zawo, kuyinselele enkulu. Uma uvula i-Span Port noma ufake empompini, kufanele ube nomthombo wethrafikhi ongadinga ukuwudlulisela kumathuluzi amaningi okuphepha angaphandle kwe-band, namathuluzi okubheka. Ngaphezu kwalokho, noma yiliphi ithuluzi elinikezwe kufanele lithole ithrafikhi kusuka kumaphoyinti amaningi kunethiwekhi ukuqeda amabala angaboni. Ngakho-ke uthola kanjani yonke ithrafikhi kwithuluzi ngalinye?
I-NPB ilungisa lokhu ngezindlela ezimbili: kungathatha okuphakelayo kwethrafikhi bese ukopisha ikhophi yalolo mgwaqo kumathuluzi amaningi ngangokunokwenzeka. Hhayi lokho kuphela, kepha i-NPB ingathatha ithrafikhi emithonjeni eminingi ngamaphoyinti ahlukene kunethiwekhi futhi uyihlanganise kwithuluzi elilodwa. Kuhlanganiswe le misebenzi emibili ndawonye, ungakwamukela wonke umthombo ovela kwisikhala bese uthinta ukuqapha itheku, uwafake lapho kufingqiwe kwi-NPB. Ngemuva kwalokho, ngokuya ngesidingo samathuluzi we-Out-of-Band okuphindaphindwa, ukuhlanganiswa, kanye nokulayisha, ukulayisha ibhalansi Ukudlulisela ithromathi yethrafikhi endaweni ngayinye engaphandle kwe-band njengendawo yakho, ku-Flow ngayinye i-Flow ngokufanele, futhi kufaka phakathi abakwazi ukubhekana nethrafikhi.
Njengoba kushiwo ngaphambili, amaphrothokholi angathunjwa kusuka kwithrafikhi, uma kungenjalo amathuluzi angavinjwa ekuhlazibeleni. I-NPB nayo inganqamula umhubhe (okufana ne-vxlan, ama-MPL, i-GPT, GRE, njll.) Ukuze amathuluzi ahlukahlukene angazulazula kulo mgwaqo.
Amaphakethe wenethiwekhi futhi asebenza njenge-hub ephakathi yokwengeza amathuluzi amasha emvelweni. Noma ngabe i-inline noma ngaphandle kwe-band, amadivaysi amasha angaxhunywa kwi-NPB, futhi ngokuhlela okusheshayo okusheshayo etafuleni lomthetho okhona, amadivaysi amasha angathola ithrafikhi yenethiwekhi ngaphandle kokuphazamisa lonke inethiwekhi noma abuyele emuva.
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.

Kulesi sihloko, sibheke kakhulu ukuthi i-Network Packet Broker iyini? Yini noma iyiphi i-NPB efanelekayo okufanele yenziwe? Ungathumela Kanjani NPB kwinethiwekhi? Ngaphezu kwalokho, yiziphi izinkinga ezijwayelekile abangazixazulula? Lokhu akuyona ingxoxo eqeda amandla ye-Network Packet Broker, kodwa ngethemba, kuyasiza ukuchaza noma yimiphi imibuzo noma ukudideka ngala madivayisi. Mhlawumbe ezinye zezibonelo ezingenhla zibonisa ukuthi i-NPB ixazulula izinkinga kanjani kunethiwekhi, noma iphakamise imicabango yokuthi ungawuthuthukisa kanjani ukusebenza kahle kwemvelo. Kwesinye isikhathi, kuzodingeka futhi sibheke izingqinamba ezithile nokuthi uthepha kanjani, i-Network Packet Broker kanye ne-probe ukuze usebenze?
