Yiziphi izinkinga ezijwayelekile ezingaxazululwa yi-Network Packet Broker?
Siwakhavelile lawa makhono futhi, kule nqubo, ezinye zezinhlelo zokusebenza ezingaba khona ze-NPB. Manje ake sigxile kumaphuzu ezinhlungu ajwayeleke kakhulu i-NPB ekhuluma ngawo.
Udinga I-Network Packet Broker lapho ukufinyelela kwenethiwekhi yakho kwethuluzi kunqunyelwe:
Inselele yokuqala yomthengisi wephakethe lenethiwekhi ukufinyelela okukhawulelwe. Ngamanye amazwi, ukukopisha/ukudlulisela ithrafikhi yenethiwekhi kuwo wonke amathuluzi okuphepha nokuqapha njengezidingo zawo, kuyinselele enkulu. Uma uvula imbobo ye-SPAN noma ufaka i-TAP, kufanele ube nomthombo wethrafikhi ongadinga ukuwudlulisela kumathuluzi amaningi okuphepha angaphandle kwebhendi, namathuluzi okuqapha. Ngaphezu kwalokho, noma yiliphi ithuluzi elinikeziwe kufanele lithole ithrafikhi evela ezindaweni eziningi kunethiwekhi ukuze kuqedwe izindawo ezingaboni lutho. Ngakho uthola kanjani yonke ithrafikhi kuthuluzi ngalinye?
I-NPB ilungisa lokhu ngezindlela ezimbili: ingathatha isifunzo sethrafikhi futhi ikopishe ikhophi yaleyo thrafikhi ibe amathuluzi amaningi ngangokunokwenzeka. Hhayi lokho kuphela, kodwa i-NPB ingathatha ithrafikhi emithonjeni eminingi ezindaweni ezihlukene kunethiwekhi futhi iyihlanganise ibe ithuluzi elilodwa. Kuhlanganiswe imisebenzi emibili ndawonye, ungakwazi ukwamukela wonke umthombo osuka ku-SPAN kanye ne-TAP ukuze ugade imbobo, futhi uyibeke esifinyezweni se-NPB. Bese, ngokwesidingo samathuluzi angaphandle kwebhendi okuphindaphinda, ukuhlanganisa, nokukopisha, ibhalansi yokulayisha edlulisela ukugeleza kwethrafikhi kuthuluzi ngalinye elingaphandle kwebhendi njengendawo yakho, ukugeleza kwethuluzi ngalinye kuzogcinwa ngokulawula okunembile, ihlanganisa nabangakwazi ukubhekana nethrafikhi.
Njengoba kushiwo ngaphambili, amaphrothokholi angasuswa kuthrafikhi, ngaphandle kwalokho amathuluzi angase avinjwe ukuthi awahlaziye. I-NPB ingaphinda inqamule umhubhe (ofana ne-VxLAN, MPLS, GTP, GRE, njll.) ukuze amathuluzi ahlukahlukene akwazi ukuhlaziya ithrafikhi equkethwe kuyo.
Amaphakethe enethiwekhi nawo asebenza njengehabhu elimaphakathi lokwengeza amathuluzi amasha endaweni. Noma ngabe ikulayini noma ingaphandle kwebhendi, amadivayisi amasha angaxhunywa ku-NPB, futhi ngokuhlela okusheshayo okumbalwa kuthebula lemithetho elikhona, amadivayisi amasha angathola ithrafikhi yenethiwekhi ngaphandle kokuphazamisa yonke inethiwekhi noma ukuyihlanganisa kabusha.
I-Network Packet Broker - Lungiselela Ithuluzi Lakho Lisebenza Kahle:
1- I-Network Packet Broker ikusiza ukuthi usebenzise ngokugcwele amadivaysi okuqapha nokuphepha. Ake sicabangele ezinye zezimo ezingaba khona ongase uhlangabezane nazo usebenzisa lawa mathuluzi, lapho amadivayisi akho amaningi okuqapha/ukuvikela angase amoshe amandla okucubungula ithrafikhi angahlobene naleyo divayisi. Ekugcineni, idivayisi ifinyelela umkhawulo wayo, iphatha kokubili ithrafikhi ewusizo nengasebenziseki kangako. Kuleli qophelo, umthengisi wamathuluzi ngokuqinisekile uzokujabulela ukukunikeza omunye umkhiqizo onamandla onamandla ngisho namandla okucubungula engeziwe ukuze uxazulule inkinga yakho... Noma kunjalo, kuzoba ukuchitha isikhathi, kanye nezindleko ezengeziwe. Uma singasusa zonke izimoto ezingenangqondo kuyo ngaphambi kokuba ithuluzi lifike, kwenzekani?
2- Futhi, cabanga ukuthi idivayisi ibheka kuphela ulwazi olusekhanda lwethrafikhi olutholayo. Ukusika amaphakethe ukuze kukhishwe umthwalo okhokhelwayo, bese udlulisela kuphela ulwazi lukanhlokweni, kunganciphisa kakhulu umthwalo wethrafikhi ethuluzini; Pho kungani kungenjalo? I-Network Packet Broker(NPB) ingenza lokhu. Lokhu kwandisa impilo yamathuluzi akhona futhi kunciphisa isidingo sokuthuthukiswa njalo.
3- Ungase uzithole uphelelwa yizindawo zokusebenzelana ezitholakalayo kumadivayisi asenesikhala esiningi samahhala. I-interface kungenzeka ingadluliseli eduze kwethrafikhi yayo etholakalayo. Ukuhlanganiswa kwe-NPB kuzoyixazulula le nkinga. Ngokuhlanganisa ukugeleza kwedatha kudivayisi eku-NPB, ungakwazi ukusebenzisa isixhumi esibonakalayo ngasinye esihlinzekwe idivayisi, uthuthukise ukusetshenziswa komkhawulokudonsa kanye nokukhulula izixhumanisi.
4- Ngenothi elifanayo, ingqalasizinda yenethiwekhi yakho ithuthelwe ku-10 Gigabytes futhi idivayisi yakho ine-gigabyte eyodwa kuphela yezindawo zokusebenzelana. Idivayisi isengakwazi ukuphatha kalula ithrafikhi kulezo zixhumanisi, kodwa ayikwazi ukuxoxisana nesivinini sezixhumanisi nhlobo. Kulokhu, i-NPB ingasebenza ngempumelelo njengesiguquli sesivinini futhi idlulisele ithrafikhi ethuluzini. Uma umkhawulokudonsa ukhawulelwe, i-NPB ingaphinda inwebe impilo yayo futhi ngokulahla ithrafikhi engabalulekile, ukwenza ukusika iphakethe, nokulayisha ukulinganisa ithrafikhi esele ezindaweni ezitholakalayo zethuluzi.
5- Ngokufanayo, i-NPB ingasebenza njengesiguquli semidiya lapho yenza le misebenzi. Uma idivayisi inokuxhumana kwekhebula yethusi kuphela, kodwa idinga ukuphatha ithrafikhi evela kusixhumanisi se-fiber optic, i-NPB ingaphinda isebenze njengomxhumanisi ukuze ithole ithrafikhi kudivayisi futhi.
