Google yakazivisa mazuva mashoma apfuura zvakatotanga nazvo kuendeswa kweHTTP / 3 uye IETF QUIC muChannel uye mune chiziviso, anoti anotarisira kuti iyi dudziro inounza imwe yekuvandudza mashandiro, kunyanya nerutsigiro rweQuIC.
QUIC ndiyo nyowani network yekutakura protocol iyo inosanganisa maficha eTCP, TLS nezvimwe. HTTP / 3 ndiyo yazvino vhezheni yeHTTP, iyo protocol inotakura huwandu hwakawanda hwewebhu traffic. HTTP / 3 inoshanda chete paQUIC.
IInternet Engineering Task Force, kana IETF, yakaunza HTTP / 2 muna 2015, uye kumwe kwekuvandudzwa kukuru kwavakaita ndiko kutsigira multiplexing.
Nekudaro, yakashandisa TCP seyakafambisa yekutakura uye nzira dzekurasikirwa muTCP, saka mapaketi akarasika anogona kukonzera kunonoka mune ese mashandiro anoita.
Nekutora QUIC, HTTP / 3 inogona kuwedzera kuvandudza maitiro ekufambisa, nekuti mapaketi akarasika mune ino kesi anongokanganisa mashandisirwo akanangana neicho.
Zvechokwadi, QUIC yakatanga kugadzirwa neGoogle uye yakatanga kuziviswa muna 2013. Kubva ipapo, protocol yasvika zera uye parizvino ine basa rekutakura chetatu chemotokari dzeGoogle.
Zvino, muna2015, kuvandudzwa kweQuIC kwakapfuudzwa mumaoko eIETF, iwo mwero mutumbi unoona nezvekuchengetedza zvibvumirano zveInternet. IETF yakavandudza QUIC neshanduko dzinoverengeka. Parizvino, pane maviri akafanana, asi akasiyana maprotocol, ayo ari: Google QUIC uye IETF QUIC.
Google yakazivisa kuti yagara ichishandisa yayo yega vhezheni yeICIC, asi kuti timu yake yeQuIC iri kubatanidzwa mukuitwa kweshanduro yepropeti yeIEFT. "Takaedza zvakanyanya kushandura Google QUIC mumakore mashanu apfuura kuti tifambirane neshanduko dzakaitwa neIETF, uye yazvino vhezheni yeGoogle QUIC ine zvakawanda zvakafanana neIETF QUIC," blog blog inoverenga kudaro. Kubva kuGoogle, pamusoro pe, akajekesa kuti zvimwe zvinhu zvaive zvisisipo.
Semuenzaniso, kusvika parizvino vazhinji vashandisi veChannel havagone kutaurirana neIETF QUIC maseva pasina kugonesa mamwe marongero emutsetse. Saizvozvo, Google yakawedzera kuti ikozvino yaona kuti IETF QUIC inodarika zvakanyanya HTTP uchienzaniswa neTLS 1.3 ichienzaniswa neTCP.
Kunyanya, kambani yakati Google yekutsvaga injini latency yakaderedzwa neinopfuura 2%. YeYouTube nguva yekupaza yakaderedzwa neinopfuura 9%. Pamusoro pezvo, kuita kwevatengi kwawedzera neinopfuura 3% pamakomputa edesktop.
Pane mbozhanhare, kuita kwevatengi kwakawedzera neanopfuura 7%. Izvi uye zvimwe zvikonzero zviri kumashure kwekuchinja kweChannel kuQuIC vhezheni yeIETF. "Tinofara kuzivisa kuti Chrome iri kushandisa rutsigiro rweIETF QUIC (kunyanya, h3-29 pilot version).
Nhasi, vangangoita 25% yevashandisi veiyo yakagadzika vhezheni yeChrome vari kushandisa h3-29, uye isu tinoronga kuwedzera iyi nhamba mumavhiki anotevera nekuenderera mberi nekuongorora data rekuita, "kambani yakadaro mune yayo blog positi.
"Chrome ichatsigira zvese IETF QUIC h3-29 uye Google QUIC vhezheni (Q050) kubvumidza nguva yemaseva anotsigira Q050 kukwidziridzwa kuIETF QUIC," akawedzera. Chrome m85 haisati yatsigira IETF QUIC 0-RTT uye Google inotarisira kuti kuita uku kungave kuri nani kana kuburitsa rutsigiro rweIETF QUIC 0-RTT mumwedzi iri kuuya. Zvakare, sezvo IETF QUIC shanduro 30 ne31 dzisina shanduko dzinogona kutyora kuenderana, kambani haina kuronga kuchinja chinongedzo "pamusoro-pe-waya".
Izvi zvinoreva kuti ichaenderera kuteedzera shanduko muIETF vhezheni, asi iyo ichaita se h3-29 / 0xff00001d.
Naizvozvo, zvinokurudzira kuti maseva arambe achitsigira h3-29 kusvika ekupedzisira maRFC apera kana vachida kudyidzana neChannel. Nekudaro, kana iyo IETF ikaita shanduko dzinoputsa kuenderana mune ramangwana chirongwa, Chrome inochinja iyo sarudzo.
