Umthengisi wePakethi yeNethiwekhi(NPB) sisixhobo esifana neswitshi senethiwekhi esinobukhulu obuhlukeneyo ukusuka kwizixhobo eziphathwayo ukuya kwiikheyisi zeyunithi ze-1U kunye ne-2U ukuya kwiikheyisi ezinkulu kunye neenkqubo zebhodi. Ngokungafaniyo neswitshi, i-NPB ayitshintshi ithrafikhi ehamba ngayo nangayiphi na indlela ngaphandle kokuba iyalelwe ngokucacileyo. Ihlala phakathi kweetaps kunye neeports ze-SPAN, ifikelela kwidatha yenethiwekhi kunye nezixhobo zokhuseleko kunye nokubeka esweni ezikumgangatho ophezulu ezihlala kwiindawo zedatha. I-NPB ingafumana ithrafikhi kwi-interface enye okanye ezingaphezulu, yenze imisebenzi ethile echazwe kwangaphambili kuloo traffic, ize emva koko iyikhuphe kwi-interface enye okanye ezingaphezulu ukuze kuhlalutywe umxholo onxulumene nemisebenzi yokusebenza kwenethiwekhi, ukhuseleko lwenethiwekhi kunye nobukrelekrele bezoyikiso.
Ngaphandle kweNetwork Packet Broker
Zeziphi iimeko ezifuna iNetwork Packet Broker?
Okokuqala, kukho iimfuno ezininzi zethrafikhi kwiindawo ezifanayo zokubamba ithrafikhi. Ukucofa okuninzi kongeza iindawo ezininzi zokusilela. Ukubukisa okuninzi (i-SPAN) kuthatha amazibuko amaninzi okubukisa, okuchaphazela ukusebenza kwesixhobo.
Okwesibini, isixhobo sokhuseleko esifanayo okanye inkqubo yohlalutyo lwethrafikhi kufuneka iqokelele ithrafikhi yeendawo ezininzi zokuqokelela, kodwa izibuko lesixhobo lilinganiselwe kwaye alinakufumana ithrafikhi yeendawo ezininzi zokuqokelela ngaxeshanye.
Nazi ezinye iingenelo zokusebenzisa iNetwork Packet Broker kwinethiwekhi yakho:
- Hlunga kwaye uhlukanise ithrafikhi engasebenziyo ukuze kuphuculwe ukusetyenziswa kwezixhobo zokhuseleko.
- Ixhasa iindlela ezininzi zokuqokelela ithrafikhi, ivumela ukuthunyelwa okuguquguqukayo.
- Ixhasa ukuhlulwa kwe-tunnel ukuze ihlangabezane neemfuno zokuhlalutya i-traffic yenethiwekhi ebonakalayo.
- Ukuhlangabezana neemfuno zokunciphisa uvakalelo oluyimfihlo, wonge izixhobo ezikhethekileyo zokunciphisa uvakalelo kunye neendleko;
- Bala ukulibaziseka kwenethiwekhi ngokusekelwe kwizitampu zexesha zepakethi yedatha efanayo kwiindawo ezahlukeneyo zokuqokelela.
Nomthengisi weePakethi zeNethiwekhi
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.
