Cloudflare Company, zvemukati zvekutumira network ye27 miriyoni zviwanikwa zveInternet uye kushandira traffic ye13% ye1000 yakakura masaiti, tsanangudzo yechiitiko chacho, semugumisiro wekuti basa rezvikamu zvakawanda zve Cloudflare network rakakanganiswa kwemaminitsi e27, kusanganisira avo vane mhosva yekuendesa motokari kuLondon, Chicago, Los Angeles, Washington, Amsterdam, Paris, Moscow uye St. . Dambudziko rakakonzerwa neshanduko isiriyo yekugadzirisa paAtlanta router.

Nekuda kwekubviswa kwekusungirirwa kune rondedzero ye prefixes, chikamu chakasara chebhuroko chakatanga kugoverwa kune ese prefixes uye router yakatanga kutumira nzira dzayo dzese dzeBGP kune ma routers emamwe mabackbones. Sezvineiwo, nzira nyowani dzaive nenzvimbo yepamusoro (yenzvimbo-inofarira 200) zvichienzaniswa neiyo yekutanga (100) yakaiswa kune dzimwe nzira neiyo otomatiki traffic optimization system. Somugumisiro, panzvimbo yekubvisa nzira kubva kumusana, nzira dzepamusoro dzeBGP dzakasvibiswa, semugumisiro weiyo traffic yakataurirwa kune mamwe mabhesi akatumirwa kuAtlanta, izvo zvakatungamirira kukurisa kwe router uye kuparara kwechikamu chetiweki.
Kuti udzivise zviitiko zvakafanana kuti zvisaitike mune ramangwana, shanduko dzakati wandei dzakarongwa kuitwa kune Cloudflare's backbon marongero neMuvhuro. Muganho pahuwandu hwehuwandu hwe prefixes (maximum-prefix) ichawedzerwa kumisangano yeBGP, iyo inovhara musana une dambudziko kana prefixes yakawandisa yakafambiswa nayo. Kana chirambidzo ichi chakawedzerwa kare, dambudziko riri mubvunzo ringadai rakakonzera kuvharwa kwemusana muAtlanta, asi ingadai isina kukanganisa kushanda kwese network, sezvo Cloudflare network yakagadzirirwa kubvumira musana wega wega kukundikana. Pakati peshanduko dzakatogamuchirwa, kudzokororwa kwezvinokosha (zvemunharaunda-zvido) yemigwagwa yemunharaunda inocherechedzwa, iyo isingazobvumiri imwe router kukanganisa traffic mune dzimwe nzvimbo dzetiweki.
