I-Internet Engineering Task Force (IETF), enoxanduva lophuhliso lwemigaqo ye-Intanethi kunye nolwakhiwo, igqibezele i-RFC yeprotocol ye-QUIC kwaye yapapasha ingcaciso ehambelanayo phantsi kwezazisi ze-RFC 8999 (iipropati zeprotocol ezizimeleyo kwinguqulelo), i-RFC 9000 (izithuthi phezu kwe-UDP), i-RFC 9001 (i-TLS i-encryption yesiteshi sonxibelelwano se-QUIC) kunye ne-RFC 9002 (ulawulo lokuxinana kunye nokufumanisa ukulahleka kwepakethi ngexesha lokuhanjiswa kwedatha).
I-RFCs ifumene isimo "soMgangatho ocetywayo", emva koko umsebenzi uya kuqalisa ukunika i-RFC umgangatho womgangatho oyilwayo (uMgangatho oYilwayo), nto leyo eneneni ithetha ukuzinziswa okupheleleyo kweprotocol kunye nokuqwalasela zonke izimvo ezenziweyo. Iprotocol ye-HTTP/3, echaza ukusetyenziswa kweprotocol ye-QUIC njengothutho lwe-HTTP/2, isekho kwinqanaba lokucaciswa kwedrafti, kodwa ngokukhawuleza iya kulungelelaniswa ne-IETF.
Kulindeleke ukuba ukumiswa komgangatho we-QUIC kuya kunika amandla ekwamkelweni okubanzi kwale protocol, kunye nophuhliso lwezandiso ezisekelwe kuyo, ezifana neWebTransport (iteknoloji yokuthumela kunye nokufumana idatha phakathi kwesikhangeli kunye nomncedisi) kunye neMASQUE. (ubuchwephesha beproxy bonxibelelwano olwandisa amandla e-SOCKS kunye ne-HTTP CONNECT, kunye nokusebenzisa i-HTTPS phezu kwe-QUIC njengothutho).
Masikhumbule ukuba i-protocol ye-QUIC (i-Quick UDP Internet Connections) iye yaphuhliswa yiGoogle ukususela ngo-2013 njengenye indlela yokudibanisa i-TCP + TLS yeWebhu, ukuxazulula iingxaki ngokuseta ixesha elide kunye namaxesha othethathethwano loqhagamshelwano kwi-TCP kunye nokuphelisa ukulibaziseka xa iipakethi zilahlekile ngexesha lokudluliselwa kwedatha. I-QUIC lulwandiso lweprotocol ye-UDP exhasa ukuphindaphindwa koqhagamshelo oluninzi kwaye ibonelele ngeendlela zofihlo ezilingana neTLS/SSL. Ngexesha lokuphuhliswa komgangatho we-IETF, utshintsho lwenziwe kwiprotocol, eyakhokelela ekuveleni kwamasebe amabini ahambelanayo, elinye le-HTTP / 3, kwaye elesibini lixhaswa nguGoogle (iChrome ixhasa zombini iinketho, kwaye iFirefox ixhasa inguqulo ye-IETF) .
Iimpawu eziphambili zeQUIC:
- Ukhuseleko oluphezulu olufana ne-TLS (ngokubalulekileyo i-QUIC ibonelela ngokukwazi ukusebenzisa i-TLS ngaphezu kwe-UDP);
- Ukulawulwa kwengqibelelo yokuhambahamba, ukuthintela ukulahleka kwepakethi;
- Ukukwazi ukuseka ngokukhawuleza uxhulumaniso (i-0-RTT, malunga ne-75% yeemeko zedatha zingathunyelwa ngokukhawuleza emva kokuthumela ipakethi yokuseta uxhulumaniso) kwaye unikeze ukulibaziseka okuncinci phakathi kokuthumela isicelo kunye nokufumana impendulo (RTT, Round Trip Time);
- Ukusebenzisa inombolo yolandelelwano eyahlukileyo xa uphinda uthumela ipakethi, ethintela ukungaqondakali ekuchongeni iipakethi ezifunyenweyo kunye nokulahla ukuphelelwa kwexesha;
- Ukulahleka kwepakethi kuchaphazela kuphela ukuhanjiswa komlambo ohambelana nayo kwaye akuyeki ukuhanjiswa kwedatha kwimijelo ehambelanayo ehanjiswa ngoxhumo lwangoku;
- Iimpawu zokulungiswa kweempazamo ezinciphisa ukulibaziseka ngenxa yokuthunyelwa kwakhona kweepakethi ezilahlekileyo. Ukusetyenziswa kweekhowudi ezikhethekileyo zokulungiswa kweempazamo kwinqanaba lepakethe ukunciphisa iimeko ezifuna ukuhanjiswa kwakhona kwedatha yepakethe elahlekileyo.
- Imida yebhloko ye-Cryptographic ihambelana nemida yepakethe ye-QUIC, eyanciphisa impembelelo yokulahlekelwa kwepakethi kwi-decoding imixholo yeepakethi ezilandelayo;
- Akukho ngxaki ngokuvalwa komgca we-TCP;
- Inkxaso yokuchonga uxhulumaniso, okunciphisa ixesha elithathayo ukuseka uxhulumaniso kwakhona kubaxhasi beselula;
- Ukubanakho kokudibanisa iindlela zokulawula ukuxinana koqhagamshelwano oluphambili;
- Isebenzisa iindlela zoqikelelo lwengqikelelo yomkhomba-ndlela ngamnye ukuqinisekisa ukuba iipakethi zithunyelwa ngemilinganiselo efanelekileyo, zithintele ukuba zingaxinani kwaye zibangele ilahleko yepakethe;
- Ukonyuka okubonakalayo kokusebenza kunye nokuphumelela xa kuthelekiswa ne-TCP. Kwiinkonzo zevidiyo ezifana ne-YouTube, i-QUIC ibonakaliswe ukunciphisa ukusebenza kwakhona xa ubukele iividiyo nge-30%.
