Nchifukwa chiyani malo anu osungira deta amafunikira ma network packet broker?

M'dziko lamakono lomwe likugwiritsidwa ntchito pa digito, malo osungira deta amagwira ntchito yofunika kwambiri pakuyang'anira ndikusunga zambiri zambiri. Chifukwa cha kufunikira kwakukulu kwa magwiridwe antchito a netiweki odalirika komanso ogwira ntchito bwino, ndikofunikira kuti malo osungira deta akhale ndi ma network packet brokers (NPBs). Ngakhale malo osungira deta sanagwiritse ntchito 100G ethernet, NPB ikhoza kukhala yothandiza kwambiri.

Mkati mwa malo osungira deta, zida zosiyanasiyana zimagwiritsidwa ntchito kuyang'anira momwe netiweki imagwirira ntchito, kupereka mawonekedwe, ndikuchepetsa ziwopsezo ndi zochita zoyipa. Zida izi zimadalira kwambiri kuchuluka kwa mapaketi kuti agwire ntchito bwino. Komabe, popanda NPB, kuyang'anira ndikugawa mapaketi awa kungakhale ntchito yovuta.

NPB imagwira ntchito ngati malo ofunikira omwe amasonkhanitsa, kukonza, ndikugawa kuchuluka kwa magalimoto pa netiweki ku zida zowunikira kapena zachitetezo zomwe zimafunikira. Imagwira ntchito ngati wapolisi woyendetsa magalimoto, kuonetsetsa kuti mapaketi oyenera afika pazida zoyenera, kukonza magwiridwe antchito awo ndikulola kusanthula bwino ndi kuthetsa mavuto.

Chimodzi mwa zifukwa zazikulu zomwe malo osungira deta amafunikira NPB ndi kuthekera kothana ndi kuthamanga kwa maukonde. Pamene ukadaulo ukupita patsogolo, kuthamanga kwa maukonde kukupitirira kukwera. Zida zodziwika bwino zowunikira maukonde sizingakhale ndi zida zothanirana ndi kuchuluka kwa mapaketi opangidwa ndi maukonde othamanga kwambiri monga 100G ethernet. NPB imagwira ntchito ngati woyang'anira magalimoto, kuchepetsa kuchuluka kwa magalimoto pa intaneti kufika pa liwiro losavuta kugwiritsa ntchito pazida, kuonetsetsa kuti kuyang'anira ndi kusanthula kolondola.

Kuphatikiza apo, NPB imapereka kuthekera kokulirapo komanso kusinthasintha kuti ikwaniritse zosowa zomwe zikuchulukirachulukira za malo osungira deta. Pamene kuchuluka kwa anthu pa netiweki kukuchulukirachulukira, zida zina zingafunike kuwonjezeredwa ku zomangamanga zowunikira. NPB imalola kuphatikiza mosavuta zida zatsopano popanda kusokoneza kapangidwe ka netiweki komwe kaliko. Imatsimikizira kuti zida zonse zowunikira ndi chitetezo zili ndi mwayi wopeza mapaketi ofunikira, mosasamala kanthu za kukula ndi zovuta za netiweki.

Malo osungira deta amakumananso ndi vuto loyang'anira kuchuluka kwa magalimoto kuchokera m'malo osiyanasiyana mkati mwa netiweki. Popeza kapangidwe kake kakufalikira kwambiri, ndikofunikira kukhala ndi mawonekedwe owonekera bwino komanso kuwongolera kuchuluka kwa magalimoto pa netiweki. NPB imagwira ntchito ngati malo olumikizirana komwe kuchuluka kwa magalimoto onse pa netiweki kumalumikizana, kupereka chithunzithunzi chokwanira cha netiweki yonse. Kuwonekera kozungulira kumeneku kumalola kuyang'anira bwino, kuthetsa mavuto, komanso kusanthula chitetezo.

Kuphatikiza apo, NPB imalimbitsa chitetezo mkati mwa malo osungira deta popereka mphamvu zogawa ma netiweki. Ndi chiwopsezo chosalekeza cha ziwopsezo za pa intaneti ndi ochita zoipa, ndikofunikira kupatula ndikuyang'ana kuchuluka kwa magalimoto pa netiweki kuti mupeze ndikuchepetsa zoopsa zilizonse zomwe zingachitike. NPB imatha kusefa ndikugawa kuchuluka kwa magalimoto pa netiweki kutengera njira zosiyanasiyana, monga adilesi ya IP yochokera kapena mtundu wa protocol, kuonetsetsa kuti kuchuluka kwa magalimoto okayikitsa akutumizidwa kuti akawunikidwenso ndikupewa kuphwanya kulikonse kwa chitetezo.

Kuphatikiza apo, NPB imagwiranso ntchito yofunika kwambiri pakuoneka kwa netiweki komanso kuyang'anira magwiridwe antchito. Imapereka chidziwitso chatsatanetsatane cha kuchuluka kwa magalimoto pa netiweki, zomwe zimathandiza oyang'anira malo osungira deta kuzindikira zopinga, mavuto ochedwa, kapena zovuta zina zilizonse zokhudzana ndi magwiridwe antchito. Pokhala ndi chithunzi chomveka bwino cha momwe netiweki imagwirira ntchito, oyang'anira amatha kupanga zisankho zodziwikiratu kuti akonze bwino netiweki ndikuwonjezera magwiridwe antchito onse.

Kuwonjezera pa maubwino amenewa, NPB imathandizanso kuti pakhale njira zowunikira maukonde mosavuta pochepetsa kuchuluka kwa zida zowunikira zomwe zimafunika. M'malo mogwiritsa ntchito zida zingapo zodziyimira pawokha pa ntchito iliyonse yowunikira, NPB imagwirizanitsa magwiridwe antchitowo kukhala nsanja imodzi. Kuphatikiza kumeneku sikungopulumutsa malo komanso kumachepetsa ndalama zokhudzana ndi kugula, kuyang'anira, ndi kusamalira zida zingapo.

Kuphatikiza apo, NPB imawongolera bwino njira zowunikira ndi kuthetsa mavuto. Pokhala ndi luso losefa ndikuwongolera mapaketi enaake ku zida zofunika, oyang'anira malo osungira deta amatha kuzindikira ndikuthetsa mavuto a netiweki mwachangu. Njira yosavuta iyi imasunga nthawi ndi zinthu, kuonetsetsa kuti nthawi yogwira ntchito ndi yochepa komanso kuti netiweki ipezeke bwino.

Pomaliza, NPB ndi gawo lofunikira kwambiri pa zomangamanga zilizonse za malo osungira deta. Imapereka mphamvu zofunikira zoyendetsera, kugawa, ndikuwongolera kuchuluka kwa magalimoto pa netiweki, kuonetsetsa kuti kuyang'anira bwino, chitetezo, ndi kusanthula magwiridwe antchito kukuchitika. Ndi kufunikira kowonjezereka kwa ma netiweki othamanga kwambiri komanso zomangamanga zogawidwa, NPB imapereka kukula, kusinthasintha, ndi kuyika pakati komwe kumafunikira kuti akwaniritse zovuta izi mwachindunji. Mwa kuyika ndalama mu NPB, ogwira ntchito pa malo osungira deta amatha kuonetsetsa kuti zomangamanga zawo za netiweki zikuyenda bwino komanso zolimba pomwe akuchepetsa zoopsa zomwe zingachitike ndikuteteza deta yamtengo wapatali.
