Kutheni iZiko lakho leDatha lifuna iiBroker zePakethi zeNethiwekhi?
Yintoni umthengisi weepakethi zenethiwekhi?
I-network packet broker (NPB) yiteknoloji esebenzisa izixhobo ezahlukeneyo zokubeka esweni ukufikelela nokuhlalutya ithrafikhi kuyo yonke inethiwekhi. Izihluzi ze-packet broker ziqokelela ulwazi lwethrafikhi kwiikhonkco zenethiwekhi kwaye zilusasaze kwisixhobo sazo sokubeka esweni inethiwekhi esifanelekileyo. Ngokuba nobuchule bokucoca obuphambili, i-NPB inokunceda ekuboneleleni ngokusebenza ngcono kwedatha, ukhuseleko oluqinileyo, kunye nendlela ekhawulezayo yokufumanisa unobangela wayo nayiphi na imiba ngokusebenzisa ubukrelekrele besicelo esiphambili. I-NPB yonyusa ukusebenza kakuhle kwenethiwekhi ngelixa ngaxeshanye inciphisa iindleko zakho. Ii-network packet brokers ngamanye amaxesha zinokubizwa ngokuba zii-data access access switches, monitoring switches, matrix switches, okanye tool aggregators.
Kwihlabathi lanamhlanje eliqhutywa yidijithali, amaziko edatha adlala indima ebalulekileyo ekulawuleni nasekugcineni ulwazi oluninzi. Ngenxa yokwanda kweemfuno zokusebenza kwenethiwekhi okuthembekileyo nokusebenzayo, kubalulekile ukuba amaziko edatha abe nee-network packet brokers (NPBs) endaweni. Nokuba iziko ledatha alikayisebenzisi i-100G ethernet okwangoku, i-NPB isenokuba luncedo kakhulu.
Ngaphakathi kwiziko ledatha, kusetyenziswa izixhobo ezahlukeneyo ukujonga ukusebenza kwenethiwekhi, ukubonelela ngokubonakala, kunye nokunciphisa izoyikiso kunye nabenzi ababi. Ezi zixhobo zixhomekeke kakhulu kuluhlu oluqhubekayo lweepakethi ukuze zisebenze ngokufanelekileyo. Nangona kunjalo, ngaphandle kwe-NPB, ukulawula nokusasaza ezi pakethi kunokuba ngumsebenzi onzima.
I-NPB isebenza njengesikhungo esiphambili esiqokelela, sihlele, kwaye sisasaze ithrafikhi yenethiwekhi kwizixhobo zokubeka esweni okanye zokhuseleko ezifunekayo. Isebenza njengegosa lezothutho, iqinisekisa ukuba iipakethi ezifanelekileyo zifikelela kwizixhobo ezifanelekileyo, iphucula ukusebenza kwazo kwaye ivumela uhlalutyo olungcono kunye nokusombulula iingxaki.
Esinye sezizathu eziphambili zokuba iziko ledatha lifune i-NPB kukukwazi ukujongana nesantya senethiwekhi esonyukayo. Njengoko iteknoloji iqhubela phambili, isantya senethiwekhi siyaqhubeka nokunyuka. Izixhobo zokujonga inethiwekhi zemveli zisenokungaxhotyiswanga ukuphatha umthamo weepakethi eziveliswa ziinethiwekhi ezinesantya esiphezulu ezifana ne-100G ethernet. I-NPB isebenza njengomlawuli wethrafikhi, icothisa ithrafikhi yenethiwekhi ukuya kwisantya esilawulekayo sezixhobo, iqinisekisa ukujonga nokuhlaziya ngokuchanekileyo.
Ngaphezu koko, i-NPB ibonelela ngokuguquguquka kunye nokuguquguquka ukuze kuhlangatyezwane neemfuno ezikhulayo zeziko ledatha. Njengoko ithrafikhi yenethiwekhi isanda, izixhobo ezongezelelweyo zinokufuneka zongezwe kwiziseko zokubeka esweni. I-NPB ivumela ukuhlanganiswa okulula kwezixhobo ezintsha ngaphandle kokuphazamisa uyilo lwenethiwekhi ekhoyo. Iqinisekisa ukuba zonke izixhobo zokubeka esweni kunye nokhuseleko zinokufikelela kwiipakethi ezifunekayo, nokuba ingakanani na inethiwekhi kunye nobunzima bayo.
Amaziko edatha ajongene nomceli mngeni wokulawula ithrafikhi kwiindawo ezahlukeneyo ngaphakathi kwenethiwekhi. Njengoko uyilo olusasazekileyo lusiba yinto eqhelekileyo, kubalulekile ukuba nokubonakala okuphakathi kunye nokulawula ithrafikhi yenethiwekhi. I-NPB isebenza njengendawo ephakathi yokuhlanganisa apho yonke ithrafikhi yenethiwekhi idibana khona, ibonelela ngesishwankathelo esipheleleyo senethiwekhi yonke. Oku kubonakala okuphakathi kuvumela ukujonga ngcono, ukusombulula iingxaki, kunye nohlalutyo lokhuseleko.
Ukongeza, i-NPB iphucula ukhuseleko kwiziko ledatha ngokubonelela ngezakhono zokwahlulahlula inethiwekhi. Ngenxa yesoyikiso esiqhubekayo sokuhlaselwa nge-intanethi kunye nabenzi bobubi, kubalulekile ukwahlula nokuhlola ithrafikhi yenethiwekhi ukuze kufunyanwe kwaye kuncitshiswe naziphi na izoyikiso ezinokubakho. I-NPB inokucoca kwaye ihlukanise ithrafikhi yenethiwekhi ngokusekelwe kwiindlela ezahlukeneyo, ezifana nedilesi ye-IP yomthombo okanye uhlobo lweprotocol, ukuqinisekisa ukuba ithrafikhi ekrokrisayo ithunyelwa ukuze ihlalutywe ngakumbi kwaye ithintele naziphi na izaphuli-mthetho ezinokubakho.
Ngaphezu koko, i-NPB ikwadlala indima ebalulekileyo ekubonakaleni kwenethiwekhi kunye nokubeka esweni ukusebenza. Inika ulwazi oluneenkcukacha malunga nokuxinana kwenethiwekhi, ivumela abaphathi beziko ledatha ukuba bachonge iingxaki, imiba yokungakhawulezi, okanye naziphi na ezinye iingxaki zokusebenza. Ngokuba nomfanekiso ocacileyo wokusebenza kwenethiwekhi, abalawuli banokwenza izigqibo ezinolwazi zokuphucula inethiwekhi kunye nokuphucula ukusebenza kakuhle ngokubanzi.
Ukongeza kwezi zibonelelo, i-NPB ikwayenza lula iziseko zokubeka esweni inethiwekhi ngokunciphisa inani lezixhobo zokubeka esweni ezifunekayo. Endaweni yokusebenzisa izixhobo ezininzi ezizimeleyo kumsebenzi ngamnye wokubeka esweni, i-NPB idibanisa imisebenzi ibe yiqonga elinye. Olu qingqo alugcini nje ngokugcina indawo kodwa lunciphisa neendleko ezinxulumene nokuthenga, ukulawula, kunye nokugcina izixhobo ezininzi.
Ngaphezu koko, i-NPB iphucula ukusebenza kakuhle kwenkqubo yokubeka esweni kunye nokusombulula iingxaki. Ngobuchule bokucoca nokuthumela iipakethi ezithile kwizixhobo ezifunekayo, abalawuli beziko ledatha banokuchonga ngokukhawuleza baze basombulule imiba yenethiwekhi. Le ndlela ilula igcina ixesha kunye nezixhobo, iqinisekisa ukuba ixesha lokungasebenzi lincinci kwaye iphucula ukufumaneka kwenethiwekhi.
Ukuqukumbela, i-NPB yinxalenye ebalulekileyo yayo nayiphi na isiseko sedatha. Ibonelela ngezakhono ezifunekayo zokulawula, ukusasaza, kunye nokwenza ngcono ithrafikhi yenethiwekhi, ukuqinisekisa ukujonga ngokufanelekileyo, ukhuseleko, kunye nohlalutyo lokusebenza. Ngenxa yemfuno ekhulayo yenethiwekhi ekhawulezayo kunye noyilo olusasaziweyo, i-NPB inikezela ngokuguquguquka, ukuguquguquka, kunye nokubekwa kwindawo enye okufunekayo ukuhlangabezana nale mingeni ngqo. Ngokutyala imali kwi-NPB, abaqhubi beziko ledatha banokuqinisekisa ukusebenza kakuhle kunye nokuqina kwesiseko senethiwekhi yabo ngelixa benciphisa ngempumelelo izoyikiso ezinokubakho kwaye bekhusela idatha exabisekileyo.
