Yiziphi izinkinga ezivamile ezingaxazululwa yi-Network Packet Broker?
Sesixoxe ngala makhono, futhi phakathi nale nqubo, ezinye zezinhlelo zokusebenza ezingaba khona ze-NPB. Manje ake sigxile ezintweni ezivame kakhulu ezixazululwa yi-NPB.
Udinga i-Network Packet Broker lapho ukufinyelela kwakho kunethiwekhi yethuluzi kunqunyelwe:
Inselelo yokuqala yomthengisi wepakethe yenethiwekhi ukufinyelela okunqunyelwe. Ngamanye amazwi, ukukopisha/ukudlulisela ithrafikhi yenethiwekhi kuwo wonke amathuluzi okuphepha nokuqapha njengoba kudingeka, kuyinselele enkulu. Uma uvula ichweba le-SPAN noma ufaka i-TAP, kumele 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. Ngakho-ke uyithola kanjani yonke ithrafikhi kuthuluzi ngalinye?
I-NPB ilungisa lokhu ngezindlela ezimbili: ingathatha ukuphakelwa kwethrafikhi bese ikopisha ikhophi eqondile yaleyo thrafikhi ibe ngamathuluzi amaningi ngangokunokwenzeka. Akukhona lokho kuphela, kodwa i-NPB ingathatha ithrafikhi kusuka emithonjeni eminingi ezindaweni ezahlukene kunethiwekhi bese iyihlanganisa ibe ithuluzi elilodwa. Uma uhlanganisa imisebenzi emibili ndawonye, ungamukela wonke umthombo kusuka ku-SPAN kanye ne-TAP ukuze uqaphe imbobo, bese uyibeka esifinyezweni se-NPB. Ngemuva kwalokho, ngokuya ngesidingo samathuluzi angaphandle kwebhendi okuphindaphinda, ukuhlanganisa, kanye nokukopisha, ibhalansi yomthwalo idlulisela ukugeleza kwethrafikhi kuthuluzi ngalinye elingaphandle kwebhendi njengendawo yakho, ukuze ukugeleza kwethuluzi ngalinye kuzogcinwa ngokulawula okunembile, kufaka phakathi okunye okungakwazi ukubhekana nethrafikhi.
Njengoba kushiwo ngaphambili, amaphrothokholi angasuswa kuthrafikhi, ngaphandle kwalokho amathuluzi angavinjelwa ekuhlaziyeni. I-NPB ingaphinde iqede umhubhe (njenge-VxLAN, i-MPLS, i-GTP, i-GRE, njll.) ukuze amathuluzi ahlukahlukene akwazi ukuhlaziya ithrafikhi equkethwe kuyo.
Amaphakethe enethiwekhi asebenza njengesikhungo esiyinhloko sokwengeza amathuluzi amasha endaweni ezungezile. Kungakhathaliseki ukuthi angaphakathi noma angaphandle kwebhendi, amadivayisi amasha angaxhunywa ku-NPB, futhi ngokuhlelwa okumbalwa okusheshayo kuthebula lemithetho elikhona, amadivayisi amasha angathola ithrafikhi yenethiwekhi ngaphandle kokuphazamisa yonke inethiwekhi noma ukuyixhuma kabusha.
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.

I-NPB inciphisa izinsiza ezichithwayo ngokuqeda ithrafikhi yangaphandle kanye nokuphambukisa ukusebenza kusuka kumathuluzi enethiwekhi ukuze bakwazi ukusebenzisa ukusebenza, okuklanyelwe ukukwenza. I-NPB ingasetshenziswa ukwengeza amazinga aphezulu okubekezelela amaphutha kanye nokwenza ngokuzenzakalela kwenethiwekhi endaweni yakho. Ithuthukisa izikhathi zokuphendula, inciphisa isikhathi sokungasebenzi, futhi ikhulule abantu ukuthi bagxile kweminye imisebenzi. Ukusebenza kahle okulethwa yi-NPB kwandisa ukubonakala kwenethiwekhi, kunciphisa izindleko zokusebenza kanye nezindleko zokusebenza, futhi kuthuthukise ukuphepha kwenhlangano.
Kulesi sihloko, sibheke kabanzi ukuthi iyini i-network packet broker? Yini okufanele yenziwe yi-NPB esebenzayo? Indlela yokufaka i-NPB kunethiwekhi? Ngaphezu kwalokho, yiziphi izinkinga ezivamile abangazixazulula? Lokhu akuyona ingxoxo ephelele ngaba-network packet brokers, kodwa ngethemba ukuthi kuyasiza ukuchaza noma yimiphi imibuzo noma ukudideka ngala madivayisi. Mhlawumbe ezinye zezibonelo ezingenhla zibonisa indlela i-NPB exazulula ngayo izinkinga kunethiwekhi, noma ziphakamise imicabango ethile yokuthi singathuthukisa kanjani ukusebenza kahle kwemvelo. Ngezinye izikhathi, kuzodingeka futhi sibheke izinkinga ezithile nokuthi i-TAP, i-network packet broker kanye ne-probe zisebenza kanjani?
