OpenVPN-i virtuaalsete privaatv\u00f5rkude paketi arendajad on esitanud ovpn-dco tuumamooduli, mis v\u00f5imaldab VPN-i j\u00f5udlust m\u00e4rkimisv\u00e4\u00e4rselt kiirendada. Kuigi moodul on praegu veel arendamisel ja keskendub ainult linux-next harule, on see juba saavutanud stabiilsuse taseme, mis v\u00f5imaldab seda kasutada OpenVPN Cloud teenuse toetamiseks. <\/p>\n

TUN-liidese p\u00f5hine konfiguratsioon v\u00f5rreldes kliendi ja serveri poole peal mooduli kasutamisega koos AES-256-GCM kr\u00fcpteerimisega on v\u00f5imaldanud saavutada 8-kordse l\u00e4bilaskev\u00f5ime kasvu (370 Mbit\/s-lt 2950 Mbit\/s-le). Mooduli kasutamine ainult kliendi poolel on suurendanud v\u00e4ljamineva liikluse l\u00e4bilaskev\u00f5imet kolm korda, ilma et see oleks muutunud sissetuleva liikluse jaoks. Mooduli kasutamine ainult kliendi poolel serverile<\/a> on suurendanud sissetuleva liikluse l\u00e4bilaskev\u00f5imet neli korda ja v\u00e4ljamineva liikluse puhul 35%.

Kiirus saavutatakse k\u00f5igi kr\u00fcptimise, paketitagumise ja sidekanali haldamise toimingute viimisega Linuxi kerneli poole, mis elimineerib konteksti vahetamisega seotud \u00fclej\u00e4\u00e4nud kulud, v\u00f5imaldab optimeerida t\u00f6\u00f6 efektiivsust, p\u00f6\u00f6rdudes otse kerneli sisemiste API-de poole, ja v\u00e4listab aeglase andmevahetuse kerneli ja kasutajaruumi vahel (kr\u00fcptimine, dekr\u00fcptimine ja suunamine toimub mooduli kaudu, ilma et liiklust saadetaks kasutajaruumi t\u00f6\u00f6tlejasse). <\/p>\n

Tuleb m\u00e4rkida, et see m\u00f5jutab negatiivselt j\u00f5udlust VPN<\/a> peamiselt teevad nad ressursimahukaid kr\u00fcptimisoperatsioone ja konteksti vahetuse t\u00f5ttu tekkivaid viivitusi. Kr\u00fcptimise kiiremaks teostamiseks on kasutatud protsessori laiendusi, nagu Intel AES-NI, kuid konteksti vahetused j\u00e4id ovpn-dco tekkimiseni kitsaskohaks. Lisaks protsessori pakutavate k\u00e4skude kasutamisele kr\u00fcptimise kiirendamiseks tagab ovpn-dco moodul ka kr\u00fcptimisoperatsioonide jagamise eraldi segmentideks ja nende t\u00f6\u00f6tlemise mitme l\u00f5ime re\u017eiimis, mis v\u00f5imaldab rakendada k\u00f5iki saadaolevaid CPU tuumasid. <\/p>\n
