Kungani isikhungo sakho sedatha sidinga abathengi be-Network Packet?
Yini i-Network Packet Broker?
I-Broker ye-Network Packet (NPB) ubuchwepheshe obusebenzisa amathuluzi ahlukahlukene okuqapha ukufinyelela nokuhlaziya ithrafikhi kwinethiwekhi kuyo yonke inethiwekhi. Izihlungi zePaket Broker ziqoqiwe imininingwane yethrafikhi kusuka ku-Network Links futhi isakasa ithuluzi layo lokuhlola inethiwekhi elifanele. Ngokuthola amandla okuhlunga okuthuthukile, i-NPB ingasiza ekuhlinzekeni ukusebenza kwedatha okungcono, ukuphepha okunzima, kanye nendlela esheshayo yokuthola imbangela yezingqinamba zanoma yiziphi izingqinamba ngokusebenzisa ubuhlakani besicelo esithuthukile. I-NPB inyusa ukusebenza kahle kwenethiwekhi ngenkathi yehlisa izindleko zakho ngasikhathi sinye. Abathengisi be-Network Packet kwesinye isikhathi bangabizwa ngokuthi ukushintshwa kwedatha, ukushintshana kokuqapha, ukushintshwa kwe-matrix, noma ama-aggregator wamathuluzi.
Kumhlaba wanamuhla oqhutshwa yikhoji, izikhungo zedatha zidlala indima ebalulekile ekuphatheni nasekugcinweni kwemininingwane enkulu yolwazi. Ngokuthola okwandayo kokusebenza kwenethiwekhi okuthembekile nokusebenzayo, kubalulekile ukuthi izikhungo zedatha zibe ne-Network Packet Broker (NPBS) endaweni. Noma ngabe isikhungo sedatha singasebenzisi i-Ethernet engu-100g Ethernet okwamanje, i-NPB isengabonakala inenzuzo enkulu.
Ngaphakathi kwesikhungo sedatha, kuqashwa amathuluzi ahlukahlukene ukuqapha ukusebenza kwenethiwekhi, ahlinzeke ukubonakala, kanye nokunciphisa izinsongo kanye nabalingisi ababi. Lawa mathuluzi athembela kakhulu ekusakazweni okuqhubekayo kwamaphakethe ukuze asebenze ngempumelelo. Kodwa-ke, ngaphandle kwe-NPB, ukuphatha kanye nokusabalalisa la maphakethe angaba ngumsebenzi oyinselele.
I-NPB isebenza njenge-hub ephakathi nendawo eqoqa, ihlele, futhi isabalalisa ithrafikhi yenethiwekhi kuya kumathuluzi wokuhlola noma wokuphepha. Isebenza njengephoyisa lomgwaqo, iqinisekisa ukuthi amaphakethe afanele afinyelela amathuluzi afanele, enza kahle ukusebenza kwawo futhi avumela ukuhlaziya okungcono nokuxazulula inkinga.
Enye yezizathu eziphambili zokuthi kungani isikhungo sedatha sidinga i-NPB yikhono lokusingatha ijubane lenethiwekhi. Njengoba kuthuthukiswa ubuchwepheshe, isivinini senethiwekhi siyaqhubeka nokuskyrocket. Amathuluzi okuqapha enethiwekhi yendabuko angeke ahlomele ukuphatha ivolumu yamaphakethe akhiqizwe amanethiwekhi aphezulu anejubane eliphakeme njenge-100g Ethernet. I-NPB isebenza njengoMlawuli Wethrafikhi, yehlisa ithrafikhi yenethiwekhi ibe ngejubane elilawulekayo lamathuluzi, ukuqinisekisa ukuqapha okunembile nokuhlaziywa.
Ngaphezu kwalokho, i-NPB ihlinzeka ngokulima nokuguquguquka ukuze kuhlaliswe izimfuno ezikhulayo zedatha yedatha. Njengoba ukwenyuka kwethrafikhi yenethiwekhi, amathuluzi angeziwe angadinga ukungezwa kwingqalasizinda yokuqapha. I-NPB ivumela ukuhlanganiswa okulula kwamathuluzi amasha ngaphandle kokuphazamisa ukwakhiwa kwenethiwekhi okukhona. Kuqinisekisa ukuthi wonke amathuluzi okuqapha kanye nokuphepha afinyelela kumaphakethe adingekayo, kungakhathalekile ukuthi usayizi wenethiwekhi nobunzima benethiwekhi.
Izikhungo zedatha nazo zibhekana nenselelo yokuphatha ithrafikhi kusuka kumaphoyinti ahlukene ngaphakathi kwenethiwekhi. Ngokwakhiwa okusatshalaliswa kube yinto evamile, kubalulekile ukuze ube nokubonakala okumaphakathi nokulawula ithrafikhi yenethiwekhi. I-NPB isebenza njengephuzu elihlanganisiwe eliphakathi nendawo lapho yonke ithrafikhi yenethiwekhi iguqukela khona, ihlinzeka ngesibukezo esiphelele senethiwekhi yonke. Lokhu kubonakala okuphakathi kuvumela ukuqapha okungcono, ukuxazulula inkinga, nokuhlaziywa kwezokuphepha.
Ngokwengeziwe, i-NPB ithuthukisa ukuphepha ngaphakathi kwesikhungo sedatha ngokunikeza amandla wenethiwekhi. Ngokusongelwa njalo kwama-cyberattacks kanye nabalingisi abanonya, kubalulekile ukuhlukanisa futhi kuhlolwe ithrafikhi yenethiwekhi ukuthola nokunciphisa noma yiziphi izinsongo ezingaba khona. I-NPB ingahlunga futhi i-gentment traffic traffic esekelwe ezinhlotsheni ezahlukahlukene, njengekheli lomthombo IP noma uhlobo lwe-protocol, ukuqinisekisa ukuthi ithrafikhi esolisayo ithunyelwa ukuze kuhlaziywe okunye futhi kuvinjelwe noma yikuphi ukwephulwa kokuphepha.
Ngaphezu kwalokho, i-NPB nayo idlala indima ebalulekile ekubonakalisweni kwenethiwekhi nokuqapha ukusebenza. Inikeza ukuqonda okunemininingwane kwithrafikhi yenethiwekhi, okuvumela abaphathi besikhungo sedatha ukuthi bakhombe amabhodlela, izingqinamba ze-latency, noma yikuphi ukukhathazeka kokusebenza. Ngokuthola isithombe esicacile sokusebenza kwenethiwekhi, abaphathi bangakwazi ukwenza izinqumo ezinolwazi ukuze basebenzise inethiwekhi futhi bathuthukise ukusebenza kahle.
Ngaphezu kwalezi zinzuzo, i-NPB futhi yenza lula ingqalasizinda yokuqapha inethiwekhi ngokunciphisa inani lamathuluzi okuqapha adingekayo. Esikhundleni sokuphamba amathuluzi amaningi esimila womsebenzi ngamunye wokuqapha, i-NPB ihlanganisa ukusebenza kwepulatifomu eyodwa. Lokhu kuhlanganisa akugcini nje ngokusindisa isikhala kodwa futhi kunciphisa izindleko ezihambisana nokuthenga, ukuphatha, nokugcina amathuluzi amaningi.
Ngaphezu kwalokho, i-NPB ithuthukisa ukusebenza kahle kwezinqubo zokuhlola nezinkinga zokuxazulula inkinga. Ngekhono lokuhlunga nokuqondisa amaphakethe athile kumathuluzi adingekayo, abaphathi besikhungo sedatha bangakhomba ngokushesha futhi baxazulule izindaba zenethiwekhi. Le ndlela etholwayo yonga isikhathi nezinsizakusebenza, iqinisekisa isikhathi sokuphumula esincane futhi yandise ukutholakala kwenethiwekhi.
Ekuphetheni, i-NPB iyingxenye ebalulekile yanoma iyiphi ingqalasizinda yesikhungo sedatha. Inikeza amakhono adingekayo okuphatha, ukusabalalisa, nokwandisa ithrafikhi yenethiwekhi, uqinisekise ukuqapha okusebenzayo, ukuphepha, kanye nokuhlaziywa kokusebenza. Ngokuthola okukhulayo okufunwa kwamanethiwekhi asheshayo kanye nezakhiwo ezisatshalaliswa, i-NPB inikezela ngesikali, ukuguquguquka, kanye nokuhlanganiswa okudingekayo ukuze kuhlangatshezwane nezinselelo zekhanda. Ngokutshala imali kwi-NPB, opharetha besikhungo sedatha bangaqinisekisa ukusebenza okubushelelezi nokuphaphama kwengqalasizinda yabo yenethiwekhi ngenkathi kunciphisa ngempumelelo izinsongo ezingaba khona kanye nokuvikela idatha ebalulekile.
