Zeziphi iingxaki eziqhelekileyo ezinokusonjululwa yiNetwork Packet Broker?
Sizigubungele ezi zakhono, kwaye kule nkqubo, ezinye zezicelo ezinokubakho ze-NPB. Ngoku makhe sigxile kwiindawo ezibuhlungu eziqhelekileyo ezijongwa yi-NPB.
Udinga iNetwork Packet Broker apho ukufikelela kwakho kwinethiwekhi yesixhobo kulinganiselwe:
Umngeni wokuqala we-network packet broker kukufikelela okulinganiselweyo. Ngamanye amazwi, ukukopa/ukudlulisela i-network traffic kuzo zonke izixhobo zokhuseleko kunye nokubeka iliso ngokweemfuno zazo, ngumceli mngeni omkhulu. Xa uvula i-SPAN port okanye ufaka i-TAP, kufuneka ube nomthombo we-traffic onokufuna ukuwuthumela kwizixhobo ezininzi zokhuseleko ezingaphandle kwebhendi, kunye nezixhobo zokubeka iliso. Ukongeza, nasiphi na isixhobo esinikiweyo kufuneka sifumane i-traffic evela kwiindawo ezininzi kwinethiwekhi ukuze kususwe amabala angabonakaliyo. Ngoko ke uyifumana njani yonke i-traffic kwisixhobo ngasinye?
I-NPB ilungisa oku ngeendlela ezimbini: ingathatha i-traffic feed ize ikopishe ikopi echanekileyo yaloo traffic ibe zizixhobo ezininzi kangangoko kunokwenzeka. Ayipheleli apho, kodwa i-NPB ingathatha i-traffic kwimithombo emininzi kwiindawo ezahlukeneyo kwinethiwekhi ize iyihlanganise ibe sisixhobo esinye. Ukudibanisa le misebenzi mibini kunye, ungamkela yonke imithombo evela kwi-SPAN kunye ne-TAP ukuze ujonge izibuko, kwaye uzibeke kwisishwankathelo se-NPB. Emva koko, ngokwemfuneko yezixhobo ezingaphandle kwebhendi zokuphindaphinda, ukuhlanganisa, kunye nokukopa, ibhalansi yomthwalo idlulisela ukuhamba kwe-traffic kwisixhobo ngasinye esingaphandle kwebhendi njengendawo ohlala kuyo, ukuze ukuhamba kwesixhobo ngasinye kugcinwe ngolawulo oluchanekileyo, ikwabandakanya ezinye ezingakwaziyo ukujongana ne-traffic.
Njengoko bekutshiwo ngaphambili, iiprotokholi zinokususwa kwitrafikhi, kungenjalo izixhobo zinokuthintelwa ekuzihlalutyeni. I-NPB inokuphelisa itonela (efana ne-VxLAN, i-MPLS, i-GTP, i-GRE, njl.njl.) ukuze izixhobo ezahlukeneyo zikwazi ukuvavanya itrafikhi engaphakathi kuyo.
Iipakethi zenethiwekhi zikwasebenza njengesikhungo esiphambili sokongeza izixhobo ezintsha kwindalo esingqongileyo. Nokuba zingaphakathi okanye azikho kwibhendi, izixhobo ezintsha zinokuqhagamshelwa kwi-NPB, kwaye ngokulungiswa okukhawulezileyo kwitheyibhile yemithetho ekhoyo, izixhobo ezintsha zinokufumana ithrafikhi yenethiwekhi ngaphandle kokuphazamisa yonke inethiwekhi okanye ukuyibuyisela umva.
Umthengisi wePakethi yeNethiwekhi - Lungiselela ukusebenza kakuhle kweZixhobo zakho:
1- I-Network Packet Broker ikunceda ukuba usebenzise ngokupheleleyo izixhobo zokubeka esweni nezokhuseleko. Makhe siqwalasele ezinye zeemeko ezinokubakho onokudibana nazo usebenzisa ezi zixhobo, apho uninzi lwezixhobo zakho zokubeka esweni/zokhuseleko zisenokuba zichitha amandla okucubungula ithrafikhi angenamsebenzi neso sixhobo. Ekugqibeleni, isixhobo sifikelela kumda waso, siphatha ithrafikhi eluncedo nengaluncedo kangako. Okwangoku, umthengisi wesixhobo ngokuqinisekileyo uya kukuvuyela ukukunika imveliso enamandla enye enamandla okusombulula ingxaki yakho... Nokuba kunjalo, kuya kuhlala kuchitha ixesha, kunye neendleko ezongezelelweyo. Ukuba singasusa zonke ithrafikhi ezingenangqiqo ngaphambi kokuba isixhobo sifike, kuza kwenzeka ntoni?
2- Kwakhona, cinga ukuba isixhobo sijonga kuphela ulwazi lwentloko yetrafikhi esiyifumanayo. Ukusika iipakethi ukuze kususwe umthwalo, uze uthumele ulwazi lwentloko kuphela, kunokunciphisa kakhulu umthwalo wendlela kwisixhobo; Kutheni ke kungenjalo? I-Network Packet Broker (NPB) ingakwenza oku. Oku kwandisa ubomi bezixhobo ezikhoyo kwaye kunciphisa isidingo sokuhlaziywa rhoqo.
3- Ungazifumana uphelelwa zii-interfaces ezikhoyo kwizixhobo ezisenendawo eninzi yasimahla. I-interface isenokungadluliseli kufutshane ne-traffic yayo ekhoyo. Ukuhlanganiswa kwe-NPB kuya kuyisombulula le ngxaki. Ngokuhlanganisa ukuhamba kwedatha kwisixhobo kwi-NPB, ungasebenzisa i-interface nganye ebonelelwe sisixhobo, uphucule ukusetyenziswa kwe-bandwidth kunye nokukhulula ii-interfaces.
4- Ngendlela efanayo, isiseko senethiwekhi yakho sifuduselwe kwi-10 Gigabytes kwaye isixhobo sakho sine-1 gigabyte yee-interfaces. Isixhobo sisenokukwazi ukuphatha ngokulula i-traffic kwezo links, kodwa asinakukwazi ukujongana nesantya see-links kwaphela. Kule meko, i-NPB inokusebenza ngokufanelekileyo njenge-speed converter kwaye idlulisele i-traffic kwisixhobo. Ukuba i-bandwidth ilinganiselwe, i-NPB inokwandisa ubomi bayo kwakhona ngokulahla i-traffic engafanelekiyo, isenza i-packet slicing, kwaye ilayishe i-traffic eseleyo kwii-interfaces zesixhobo ezikhoyo.
5- Ngokufanayo, i-NPB ingasebenza njengesixhobo sokuguqula imidiya xa isenza le misebenzi. Ukuba isixhobo sinojongano lwentambo yobhedu kuphela, kodwa sifuna ukusingatha ithrafikhi evela kwikhonkco le-fiber optic, i-NPB ingasebenza kwakhona njengomlamli ukuze ifumane ithrafikhi kwisixhobo kwakhona.
