Kutheni iZiko leDatha yakho lifuna iiBroker zePakethi yeNethiwekhi?
Yintoni umthengisi wepakethe yenethiwekhi?
Umthengisi wepakethe yenethiwekhi (NPB) iteknoloji esebenzisa izixhobo ezahlukeneyo zokubeka iliso ukufikelela kunye nokuhlalutya i-traffic kwinethiwekhi. Iifilitha ze-packet broker ziqokelele ulwazi lwetrafikhi kwiikhonkco zenethiwekhi kwaye zisasazeke kwisixhobo esifanelekileyo sokubeka iliso kwinethiwekhi. Ngokuba nobuchule obuphambili bokucoca, i-NPB inokunceda ukubonelela ngokusebenza kwedatha engcono, ukhuseleko olungqongqo, kunye nendlela ekhawulezayo yokumisela unobangela wayo nayiphi na imiba ngokusebenzisa ubukrelekrele besicelo esiphambili. I-NPB yonyusa ukusebenza kwenethiwekhi ngelixa ngaxeshanye isehlisa iindleko zakho. Abathengisi bepakethe yenethiwekhi ngamanye amaxesha banokubhekiswa kubo njengotshintsho lokufikelela kwidatha, iiswitshi zokubeka iliso, iiswitshi zematrix, okanye izixhobo ezidibanisa izixhobo.
Kwihlabathi lanamhlanje eliqhutywa yidijithali, amaziko edatha adlala indima ebalulekileyo ekulawuleni nasekugcineni isixa esikhulu solwazi. Ngokunyuka kweemfuno zentsebenzo yenethiwekhi ethembekileyo nesebenzayo, kubalulekile ukuba amaziko edatha abe ne-network packet brokers (NPBs) endaweni. Nokuba iziko ledatha alikasebenzisi i-ethernet ye-100G okwangoku, i-NPB isengabonakalisa ukuba luncedo kakhulu.
Kwiziko ledatha, izixhobo ezahlukeneyo ziqeshwe ukujonga ukusebenza kwenethiwekhi, ukubonelela ngokubonakala, kunye nokunciphisa izoyikiso kunye nabadlali ababi. Ezi zixhobo zithembele kakhulu kwimijelo eqhubekayo yeepakethi ukuze zisebenze ngokufanelekileyo. Nangona kunjalo, ngaphandle kwe-NPB, ukulawula kunye nokuhambisa ezi pakethi kunokuba ngumsebenzi onzima.
I-NPB isebenza njengendawo esembindini eqokelela, iququzelele, kwaye isasaze itrafikhi yothungelwano kwindawo efunekayo yokubeka iliso okanye izixhobo zokhuseleko. Isebenza njengepolisa lezendlela, iqinisekisa ukuba iipakethi ezifanelekileyo zifikelela kwizixhobo ezifanelekileyo, ukuphucula ukusebenza kwazo kunye nokuvumela uhlalutyo olungcono kunye nokusombulula ingxaki.
Esinye sezizathu eziphambili zokuba kutheni iziko ledatha lidinga i-NPB yikhono lokusingatha isantya sothungelwano esonyukayo. Njengoko itekhnoloji ihambela phambili, isantya sothungelwano siyaqhubeka sinyuka. Izixhobo zokubeka iliso zenethiwekhi eziqhelekileyo zingenakho ukuxhotyiswa ukuphatha umthamo weepakethi eziveliswa ngamanethiwekhi anesantya esiphezulu njenge-100G ethernet. I-NPB isebenza njengomlawuli wezithuthi, ukunciphisa i-traffic traffic kwisantya esilawulekayo sezixhobo, ukuqinisekisa ukubeka iliso kunye nokuhlalutya ngokuchanekileyo.
Ngaphaya koko, i-NPB ibonelela nge-scalability kunye nokuguquguquka ukulungiselela iimfuno ezihlala zikhula zeziko ledatha. Njengoko i-traffic traffic inyuka, izixhobo ezongezelelweyo zingadinga ukongezwa kwiziseko zokuhlola. I-NPB ivumela ukuhlanganiswa okulula kwezixhobo ezitsha ngaphandle kokuphazamisa i-architecture ekhoyo yenethiwekhi. Iqinisekisa ukuba zonke izixhobo zokubeka iliso kunye nokhuseleko zifikelela kwiipakethi ezifunekayo, kungakhathaliseki ubungakanani benethiwekhi kunye nobunzima.
Amaziko eenkcukacha ajongene nomngeni wokulawula i-traffic kwiindawo ezahlukeneyo ngaphakathi kwenethiwekhi. Ngolwakhiwo olusasaziweyo oluya luxhaphaka ngakumbi, kubalulekile ukuba nembonakalo esembindini kunye nolawulo kwitrafikhi yenethiwekhi. I-NPB isebenza njengendawo yokudibanisa ephakathi apho yonke i-traffic traffic idibanisa, inikezela ngombono obanzi wenethiwekhi yonke. Oku kubonakala kusembindini kuvumela ukubeka iliso okungcono, ukulungisa iingxaki, kunye nohlalutyo lokhuseleko.
Ukongeza, i-NPB iphucula ukhuseleko ngaphakathi kwiziko ledatha ngokubonelela ngezakhono zokwahlulahlula kwenethiwekhi. Ngesoyikiso esihlala sikhona sohlaselo lwe-cyber kunye nabadlali abakhohlakeleyo, kubalulekile ukwahlula kunye nokuhlola itrafikhi yothungelwano ukubona kunye nokunciphisa naziphi na izoyikiso ezinokubakho. I-NPB inokucoca kwaye ihlukanise i-traffic yenethiwekhi ngokusekelwe kwiikhrayitheriya ezahlukeneyo, ezifana nedilesi ye-IP yomthombo okanye uhlobo lweprotocol, ukuqinisekisa ukuba i-traffic ekrokrelayo ithunyelwa kuhlalutyo olongezelelweyo kunye nokuthintela nakuphi na ukwaphulwa kokhuseleko olunokwenzeka.
Ngaphezu koko, i-NPB ikwadlala indima ebalulekileyo ekubonakaleni kothungelwano kunye nokubekwa kweliso kokusebenza. Ibonelela ngeenkcukacha ezicacileyo kwitrafikhi yenethiwekhi, ivumela abalawuli beziko ledatha ukuba bachonge imiqobo, imiba ye-latency, okanye nayiphi na enye inkxalabo yokusebenza. Ngokuba nomfanekiso ocacileyo womsebenzi womnatha, abalawuli banokwenza izigqibo ezinolwazi zokwandisa inethiwekhi kunye nokuphucula ukusebenza kakuhle ngokubanzi.
Ukongeza kwezi nzuzo, i-NPB yenza lula uthungelwano lweziseko zokubeka iliso ngokunciphisa inani lezixhobo zokubeka iliso ezifunekayo. Esikhundleni sokusebenzisa izixhobo ezininzi ezizimeleyo kumsebenzi ngamnye wokubeka iliso, i-NPB idibanisa imisebenzi kwiqonga elinye. Oku kudityaniswa akugcini nje ukugcina indawo kodwa kunciphisa iindleko ezinxulumene nokuthenga, ukulawula nokugcina izixhobo ezininzi.
Ngaphaya koko, i-NPB iphucula ukusebenza kakuhle kokubeka iliso kunye neenkqubo zokusombulula ingxaki. Ngokukwazi ukucoca kunye nokuqondisa iipakethi ezithile kwizixhobo ezifunekayo, abalawuli beziko ledatha banokubona ngokukhawuleza kwaye basombulule imiba yenethiwekhi. Le ndlela ilungelelanisiweyo igcina ixesha kunye nezibonelelo, iqinisekisa ixesha elincinci lokunciphisa kunye nokwandisa ukufumaneka kwenethiwekhi.
Ukuqukumbela, i-NPB yinxalenye ebalulekileyo yalo naliphi na isiseko seziko ledatha. Ibonelela ngezakhono eziyimfuneko zokulawula, ukusabalalisa, kunye nokwandisa i-traffic yenethiwekhi, ukuqinisekisa ukubeka iliso, ukhuseleko kunye nohlalutyo olusebenzayo. Ngokunyuka kweemfuno zothungelwano olukhawulezayo kunye nokusabalalisa izakhiwo, i-NPB inikezela nge-scalability, i-flexibility, kunye ne-centralization efunekayo ukuhlangabezana nale mingeni. Ngotyalo-mali kwi-NPB, abaqhubi beziko ledatha banokuqinisekisa ukusebenza kakuhle kunye nokomelela kweziseko zabo zenethiwekhi ngelixa ngokufanelekileyo ukunciphisa izisongelo ezinokuthi zikhusele idatha ebalulekileyo.
