Yana da mahimmanci a nuna hakan Google ya haɓaka QUIC (Haɗin Intanet na UDP mai sauri) tun 2013 azaman madadin TCP + TLS kunshin yanar gizo, wanda ke warware matsaloli tare da dogon sanyi da lokutan tattaunawa don haɗin TCP kuma yana kawar da jinkiri cikin asarar fakiti yayin canja wurin bayanai.
QUIC mai dacewa ne da yarjejeniyar UDP wacce ke goyan bayan yawaitar hanyoyin sadarwa da yawa kuma yana samar da hanyoyin ɓoyewa kwatankwacin TLS / SSL.
An riga an riga an gina yarjejeniya da ake magana a kai don samar da kayan aikin sabar Google, wani ɓangare ne na Chrome, an tsara shi don haɗawa a cikin Firefox, kuma ana amfani da shi sosai don yin buƙatun abokin ciniki akan sabar Google.
Daga cikin manyan halayen QUIC wadanda suka fito sune:
- Babban tsaro, kwatankwacin TLS (a zahiri, QUIC yana ba da ikon amfani da TLS akan UDP)
- Gudanar da mutuncin mutunci wanda ke hana asarar fakiti
- Ikon kafa haɗin kai tsaye (0-RTT, a kusan kashi 75% na lamura, ana iya watsa bayanai kai tsaye bayan aika fakitin saitin haɗin haɗi) da kuma tabbatar da jinkiri kaɗan tsakanin aika buƙata da karɓar amsa (RTT, Zagayewar Lokaci)
- Ba amfani da lambar jerin iri ɗaya lokacin sake aikawa da fakiti, wanda ke hana shubuha cikin ƙayyade fakiti da aka karɓa kuma ya kawar da lokutan jira

Hakanan an haskaka cewa yana amfani da dabarar hango faren bandwidth a kowace hanya don tabbatar da ingantaccen isar da fakiti, hana shi kai wa ga cunkoson da ake lura da asarar fakiti;
Har da gagarumar aiki da nasarorin da aka samu akan TCP. Don hidimomin bidiyo kamar YouTube, QUIC ya nuna ragin 30% a cikin ayyukan sake ɓoye lokacin kallon bidiyo.
Yarjejeniyar HTTP / 3 ta daidaita amfani da QUIC azaman jigilar HTTP / 2. Don ba da damar HTTP / 3 da kuma QUIC sigar ta 23 daftarin bayanan IETF, dole ne a gudanar da Chrome tare da zaɓuɓɓukan "-enable-quic –quic-version = h3-23" sannan kuma lokacin da aka buɗe shafin gwajin gwaji .rocks: 4433 in yanayin duba hanyar sadarwa a cikin kayan aikin masu tasowa, aikin HTTP / 3 zai nuna a matsayin "http / 2 + quic / 99".
