Selon les statistiques de Google, par rapport \u00e0 HTTP sur TCP+TLS 1.3, le protocole IETF QUIC a montr\u00e9 une r\u00e9duction des latences de 2 % lors des recherches sur Google et une diminution du temps de mise en m\u00e9moire tampon sur YouTube de 9 %, avec une augmentation de la bande passante de 3 % pour les syst\u00e8mes de bureau et de 7 % pour les syst\u00e8mes mobiles.<\/p>\n<p>HTTP\/3 <noindex><a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=49594\">standardise<\/a><\/noindex> l'utilisation du protocole QUIC comme transport pour HTTP\/2. Le protocole QUIC (Quick UDP Internet Connections) est d\u00e9velopp\u00e9 par Google depuis 2013 en tant qu'alternative \u00e0 la combinaison TCP+TLS pour le web, r\u00e9solvant les probl\u00e8mes li\u00e9s \u00e0 un long temps d'\u00e9tablissement et de n\u00e9gociation de connexions dans TCP et \u00e9liminant les d\u00e9lais en cas de perte de paquets lors de la transmission des donn\u00e9es. QUIC est une superposition du protocole UDP, supportant le multiplexage de plusieurs connexions et fournissant des m\u00e9thodes de cryptage \u00e9quivalentes \u00e0 TLS\/SSL. Au cours du processus de standardisation au sein de l'IETF, des modifications ont \u00e9t\u00e9 apport\u00e9es au protocole, conduisant \u00e0 l'\u00e9mergence de deux branches coexistantes, l'une
