Kutheni le nto iZiko lakho ledatha lifuna abathengisi beepakethi zenethiwekhi?
Yintoni umthengisi wepakethi yenethiwekhi?
Ipakethi yepakethi yenethiwekhi (i-NPB) yitekhnoloji esebenzisa izixhobo ezahlukeneyo zokubeka iliso ukufikelela kunye nokuhlalutya ithrafikhi kwinethiwekhi. Iifilitha zepakethi zepakethi eziqokelele ulwazi lweendlela eziqokeleleyo amakhonkco enethiwekhi kwaye zisasaze kwisixhobo esifanelekileyo sokubeka iliso. Ngokwenza ubuchule bokufihlakala, i-NPB inokunceda ekuboneleleni ngedatha engcono yedatha, ukhuseleko olunobunzima, kunye nendlela ekhawulezayo yokufumanisa unobangela wento esetyenziswayo ngenjongo yokuphambuka kwesicelo esiphambili. I-NPB inyusa ukusebenza ngenethiwekhi ngelixa kwangaxeshanye ukuthoba iindleko zakho. Iipakethi zepakethi zenethiwekhi zinokuthi ngamanye amaxesha zitshintshelwe kwi-switches yokufikelela kwidatha, ukubeka esweni ukutshintsha, ukutshintshela kweMatrix, okanye izixhobo ze-Aggregares.
Kwihlabathi eliqhutywa yi-proby eqhutywa ngokuhlwayo, amaziko edatha adlala indima ebalulekileyo ekulawuleni nasekugcine izixa ezinzima zolwazi. Ngeemfuno ezonyukayo zokusebenza okuthembekileyo kunye nokufanelekileyo Nokuba iziko ledatha alinakukhupha i-100g Ethernet okwangoku, i-NPB isenokufana nokuba luncedo kakhulu.
Kwiziko ledatha, izixhobo ezahlukeneyo zisetyenziswa ukubeka iliso kwindlela yokusebenza kwenethiwekhi, ukubonelela ngokubonakala, kunye nokunciphisa izoyikiso kunye nabadlali ababi. Ezi zixhobo zixhomekeke kakhulu kumjelo oqhubekayo weepakethi zisebenze kakuhle. Nangona kunjalo, ngaphandle kwe-NPB, ukulawula nokusasaza ezi pakethi kunokuba ngumceli mngeni.
I-NPB isebenza njengendawo ephakathi hub eqokelela, iqokelele, kwaye ihambisa itrafikhi yenethiwekhi kwizixhobo ezifunekayo okanye zokhuseleko. Isebenza njengekopi yendlela, iqinisekisa ukuba iipakethi ezifanelekileyo zifikelela kwizixhobo ezifanelekileyo, zokwenza intsebenzo yazo kunye nokuvumela uhlalutyo olungcono kunye nokuzihlaziya ingxaki.
Esinye sezizathu eziphambili zokuba iziko ledatha lifuna i-NPB kukukwazi ukuphatha isantya esiyinethiwekhi. Njengokuqhubela phambili kwetekhnoloji, isantya senethiwekhi siyaqhubeka kwi-skyrocket. Izixhobo zokubeka iliso kwinethiwekhi azinakuxhotyiswa ukuphatha ivolumu yeepakethi eziveliswe ziinethiwekhi eziphakamileyo ezinjenge-100g ethernet. I-NPB isebenza njengoMlawuli weTrafiki, icothisa ithrafikhi yenethiwekhi kwisantya esilawulwayo sezixhobo, ekuqinisekiseni ukubeka iliso kunye nohlalutyo oluchanekileyo.
Ngaphaya koko, i-NPB ibonelela ngokukhululeka kunye nokuguquguquka ukulungiselela iimfuno ezihlala zikhula kwiziko ledatha. Njengokunyuswa kwendlela yenethiwekhi, izixhobo ezongeziweyo kusenokufuneka zongezwe kwizibonelelo zokujonga. I-NPB ivumela ukudityaniswa okulula kwezixhobo ezintsha ngaphandle kokuphazamisa inethiwekhi ekhoyo yenethiwekhi. Iqinisekisa ukuba zonke izixhobo zokubeka esweni kunye nezokhuseleko zinokufikelela kwiipakethi ezifunekayo, ngaphandle kwesayizi yenethiwekhi kunye nobunzima.
Amaziko edatha ajongana nomceli mngeni wokulawula ukugcwala kwabantu kwiindawo ezahlukeneyo ngaphakathi kwenethiwekhi. Ngoyilo olusasaziweyo ukuba luxhaphake ngakumbi, kubalulekile ukuba ubonakale ngokubonakalayo kunye nokulawula ngaphezulu kwendlela yenethiwekhi. I-NPB isebenza njengendawo ephakathi yokuhlanganisa indawo apho zonke iitrafikhi zendlela, zibonelela ngesishwankathelo esibanzi senethiwekhi yonke. Oku kubonakala ngokubonakalayo kuvumela ukubeka iliso, ukulungisa ingxaki, kunye nohlalutyo lwezokhuseleko.
Ukongeza, i-NPB iphucula ukhuseleko ngaphakathi kweziko ledatha ngokubonelela ngezakhono zecandelo lenethiwekhi. Ngoyisongelo rhoqo le-cyberattacks kunye nabadlali obuthathaka, kubalulekile ukuba sihlukane kwaye sihlole ithuthuthu lesithuthi ukufumana kwaye linciphise naziphi na izoyikiso. I-NPB inakho ukucoca kunye nethrekhi yendlela yecandelo elisekwe kwiindlela ezahlukeneyo ze-IP okanye i-IP ye-IP okanye i-protocol yohlobo, iqinisekisa ukuba ukrokrela ukuba kuthunyelwe uhlalutyo olongezelelekileyo.
Ngapha koko, i-NPB ikwadlala indima ebalulekileyo kwinethiwekhi yokubonakala kwenethiwekhi kunye nokubeka esweni ukusebenza. Inika ulwazi olucacileyo lwezithuthi zenethiwekhi, zivumela abalawuli beziko ledatha ukufumana ibhotile, imicimbi yokufunda, okanye naziphi na ezinye iinkxalabo zomsebenzi. Ngokwenza umfanekiso ocacileyo wentsebenzo yenethiwekhi, abalawuli banokwenza izigqibo ezizizo zokuphucula inethiwekhi kunye nokuphucula ukusebenza kakuhle.
Ukongeza kwezi zibonelelo, i-NPB ikwakhalula lula iziseko zoncedo zokuhlola inethiwekhi ngokunciphisa inani izixhobo zokubeka esweni ezifunekayo. Endaweni yokuphelisa izixhobo ezininzi zokumamela ukuya kumsebenzi ngamnye wokubeka esweni, i-NPB idibanisa ukusebenza kwiqonga elinye. Oku kudityaniswa akugciniwe kuphela indawo kodwa kunciphisa iindleko ezinxulumene nokuthenga, ukulawula, nokugcina izixhobo ezininzi.
Ngaphaya koko, i-NPB iphucula ukusebenza kakuhle kweenkqubo zokubeka esweni kunye nokuhlaziya iingxaki. Ngobuchule bokucoca kwaye bathumele iipakethi ezithile ngqo kwizixhobo ezifunekayo, abalawuli beziko ledatha banokuchonga kwaye basombulule imiba yenethiwekhi. Le ndlela yokuhambisa isuse igcina ixesha kunye nezixhobo, iqinisekisa ixesha lokuphumla elincinci kwaye lindise ukufumaneka kwenethiwekhi.
Ukuqukumbela, i-NPB yeyona nto ibalulekileyo kuzo naziphi na iziseko zophuhliso zedatha. Inika amandla ayimfuneko okulawula, ukuhambisa, kunye nokwandisa ukugcwala kwenethiwekhi, ukuqinisekisa ukubeka iliso, ukhuseleko, kunye nohlalutyo lwentsebenzo. Ngeemfuno ezikhulayo zenethiwekhi ezihamba ngesantya esiphezulu kwaye zasasazwa ngokwakha, i-NPB inikezela ukwenziwa, i-NPB inikezela ukuguquguquka, ukuguquguquka, kunye nokufezekiswa okufunekayo ukuhlangabezana nale miceli mngeni. Ngokutyala imali kwi-NPB, iZiko leDatha ledatha linokuqinisekisa ukusebenza kakuhle kunye nokulimala kwezibonelelo zawo zenethiwekhi ngelixa kunciphisa ngokufanelekileyo izoyikiso ezinokubakho kunye nokukhusela idatha exabisekileyo.
