Google berichtet<\/a><\/noindex> \u00fcber den Beginn des Austauschs der eigenen Protokollversion QUIC<\/a><\/noindex> durch die in der IETF-Spezifikation entwickelte Variante. Die in Chrome verwendete QUIC-Variante von Google weicht in einigen Details von der Variante aus IETF-Spezifikationen<\/a><\/noindex>. Chrome unterst\u00fctzt beide Protokollvarianten, hat aber standardm\u00e4\u00dfig weiterhin seine eigene QUIC-Variante verwendet. <\/p>\n

Ab heute sind 25% der Benutzer der stabilen Chrome-Version auf die Verwendung von IETF QUIC umgeschaltet, und in naher Zukunft wird dieser Anteil steigen. Laut Google Statistiken zeigte das IETF QUIC-Protokoll im Vergleich zu HTTP \u00fcber TCP+TLS 1.3 eine Verz\u00f6gerungsreduzierung bei der Suche in Google Search um 2% und eine Verringerung der Pufferzeit in YouTube um 9%, w\u00e4hrend die Bandbreite f\u00fcr Desktop-Systeme um 3% und f\u00fcr mobile Systeme um 7% erh\u00f6ht wurde.<\/p>\n

HTTP\/3. standardisiert<\/a><\/noindex> Die Verwendung des QUIC-Protokolls als Transportmittel f\u00fcr HTTP\/2. Das QUIC-Protokoll (Quick UDP Internet Connections) wird seit 2013 von Google als Alternative zu TCP+TLS f\u00fcr das Web entwickelt. Es l\u00f6st Probleme mit langen Verbindungsaufbau- und Aushandlungszeiten in TCP und beseitigt Verz\u00f6gerungen bei Paketverlusten w\u00e4hrend der Daten\u00fcbertragung. QUIC ist eine Erweiterung des UDP-Protokolls, die die Multiplexierung mehrerer Verbindungen unterst\u00fctzt und Verschl\u00fcsselungsmethoden bietet, die TLS\/SSL entsprechen. Im Rahmen der Standardisierung bei der IETF wurden \u00c4nderungen am Protokoll vorgenommen, was zur Schaffung von zwei parallel existierenden Zweigen f\u00fchrte, einem f\u00fcr HTTP\/3 und einem anderen, der von Google unterst\u00fctzt wird.<\/p>\n
