Onjiniyela kamuva nje abasemuva kusuka kusiphequluli sewebhu seGoogle Chrome, kukhishwe izindaba zokungezwa kokusekelwa kwephrothokholi ye-HTTP / 3 ekwakhiweni kokuhlolwa kwe-Chrome Canary, esebenzisa i-plugin ukunika amandla i-HTTP ngaphezu kwe-QUIC.
Iphrothokholi ye-QUIC uqobo ingezwe kusiphequluli eminyakeni emihlanu eyedlule futhi kusukela lapho ibisetshenziselwa ukwenza ngcono umsebenzi ngezinsizakalo zeGoogle. Ngasikhathi sinye, inguqulo ye-QUIC ye-Google esetshenziswe ku-Chrome yehlukile kweminye imininingwane kusuka enguqulweni yezincazelo ze-IETF, kepha manje ukusetshenziswa sekuyahambisana.
I-Google Chrome Canary isanda kuba yisiphequluli sokuqala (esitholakalayo) sokuhlanganisa (kakhulu) sokuhlola #I -QUIC nokuxhaswa kwe-HTTP / 3!
Faka amafulegi "- enable-quic –quic-version = h3-23" futhi kufanele ubone u- "http / 2 + quic / 99" ekhombisa ama-devtools, okuyi-http3 efihlekile! pic.twitter.com/5Fhui46h3x

Kubalulekile ukukugqamisa lokho I-Google isungule i-QUIC (Ukuxhuma Okusheshayo Kwe-inthanethi kwe-UDP) kusukela ngo-2013 njengenye indlela yephakheji ye-TCP + TLS yeWebhu, exazulula izinkinga ngezikhathi zokumisa ezinde nezingxoxo zokuxhuma kwe-TCP futhi iqede ukubambezeleka kokulahleka kwepakethe ngesikhathi sokudluliswa kwedatha.
I-QUIC ihambisana nephrothokholi ye-UDP esekela ukuphindaphindwa kokuxhuma okuningi futhi inikeza izindlela zokubethela ezilingana ne-TLS / SSL.
Iphrothokholi okukhulunywa ngayo isivele yakhelwe kwingqalasizinda yeseva yeGoogle, iyingxenye ye-Chrome, ihlelelwe ukufakwa kuFirefox, futhi isetshenziswa ngenkuthalo ukusebenzela izicelo zamakhasimende kumaseva weGoogle.
Phakathi kwezici eziyinhloko ze-QUIC ezivelele yilezi:
- Ukuphepha okuphezulu, okufana ne-TLS (empeleni, i-QUIC inikeza amandla wokusebenzisa i-TLS ngaphezulu kwe-UDP)
- Ukulawulwa kobuqotho bokugeleza okuvimbela ukulahleka kwepakethe
- Ikhono lokusungula ngokushesha ukuxhumana (i-0-RTT, kumacala angaba ngu-75%, idatha ingadluliselwa ngokushesha ngemuva kokuthumela iphakethe lokusetha uxhumano) nokuqinisekisa ukubambezeleka okuncane phakathi kokuthumela isicelo nokuthola impendulo (i-RTT, Isikhathi Sokujikeleza)
- Ukungasebenzisi inombolo efanayo yokulandelana lapho uthumela kabusha iphakethe, eligwema ukungaqondakali ekunqumeni amaphakethe atholiwe futhi kuqede izikhathi zokulinda
- Ukulahlekelwa yiphakethe kuthinta ukulethwa kokusakazwa okuhambisana nakho kuphela futhi akumisi ukulethwa kwedatha emifudlaneni edluliselwe ngokufana nokuxhumeka kwamanje
- Iphutha amathuluzi okulungisa anciphisa ukubambezeleka ngenxa yokudluliswa kabusha kwamaphakethe alahlekile.
- Ukusetshenziswa kwamakhodi okulungisa amaphutha wezinga elikhethekile ukunciphisa izimo ezidinga ukudluliswa kabusha kwedatha yepakethe elahlekile.
- Imikhawulo ye-cryptographic yamabhulokhi ihambelana nemikhawulo yamaphakethe we-QUIC, kunciphisa umphumela wokulahleka kwephakethe ekuchazeni okuqukethwe kwamaphakethe alandelayo
- Akunazinkinga ngokuvimba ulayini we-TCP
- Ukusekelwa kokokuhlonza ukuxhumeka, okunciphisa isikhathi sokusungula ukuxhumana kabusha kwamakhasimende weselula
- Amandla wokuxhuma izindlela ezithuthukile zokulawula ukulayishwa okugcwele
Kuyaqokonyiswa futhi ukuthi isebenzisa inqubo yokubikezela umkhawulokudonsa ohlangothini ngalunye ukuqinisekisa ukushuba okuphelele kokulethwa kwamaphakethe, ukuvimbela ukuthi kufinyelele esimweni sokuminyana lapho kutholakala khona ukulahleka kwepakethe;
Kanye ne ukusebenza okumangazayo nokuzuza kokusebenza ngaphezu kwe-TCP. Kumasevisi wevidiyo afana ne-YouTube, i-QUIC ikhombise ukwehliswa okungu-30% kokusebenza kabusha kwebhafa lapho ubuka amavidiyo.
Iphrothokholi ye-HTTP / 3 ifanisa ukulinganiswa kokusetshenziswa kwe-QUIC njengokuthuthwa kwe-HTTP / 2. Ukuze unike amandla i-HTTP / 3 nenguqulo ye-QUIC yezincazelo ezingama-23 ezisalungiswa ze-IETF, i-Chrome kumele isebenze ngezinketho "- enable-quic –quic-version = h3-23" bese kuthi lapho isayithi lokuhlola i-quic livulwa .rocks: 4433 in imodi yokuhlola inethiwekhi kumathuluzi wonjiniyela, umsebenzi we-HTTP / 3 uzoboniswa njenge- "http / 2 + quic / 99".
Uma kuqhathaniswa nephakethe elahlekile ngokuxhuma okuhambisanayo kwe-HTTP, ukuxhumana okukodwa kuphela kokuningi okuzomiswa, okusho ukuthi i-QUIC ingakusekela ukulethwa ngaphandle kwe-oda ukuze iphakethe elahlekile lingabi nomthelela omncane.
Si ufuna ukwazi kabanzi ngayo ngalokhu, ungabonisana isixhumanisi esilandelayo.
