Chrome inotanga kuyedza paHTTP / 3 protocol

HTTP3Chrome

Vagadziri munguva pfupi yapfuura vari kumashure kubva kuGoogle Chrome web browser, yakaburitsa nhau dzekuwedzera kwekutsigirwa kweiyo HTTP / 3 protocol kune yekuyedza kuvaka kweCanary Canary, iyo inoshandisa plugin kugonesa HTTP pamusoro peQUIC.

Iyo QuIC protocol pachayo yakawedzerwa kubhurawuza makore mashanu apfuura uye kubvira ipapo yanga ichishandiswa kukwidzirisa basa neGoogle masevhisi. Panguva imwecheteyo, iyo QUIC vhezheni yeGoogle yaishandiswa muChannel yakasiyana mune mamwe maratidziro kubva kuiyo vhezheni yeIETF zvirevo, asi izvozvi mashandisiro acho awiriraniswa.

 

Izvo zvakakosha kuratidza izvo Google yakagadzira QUIC (Kurumidza UDP Internet Kubatanidza) kubvira 2013 senge imwe nzira kune TCP + TLS package yeWebhu, iyo inogadzirisa matambudziko nekureba kumisikidza uye nguva dzekutaurirana kwekubatana kweTCP uye kubvisa kunonoka pakurasika kwepaketi panguva yekufambisa data.

QUIC mubatsiri kune iyo UDP protocol inotsigira kuwanda kwekubatana kwakawanda uye inopa nzira dzekunyorera dzakaenzana neTLS / SSL.

Iyo protocol iri kubvunzwa yakatovakwa muGoogle dura rezvivakwa, chikamu cheChannel, chakarongerwa kuiswa muFirefox, uye chinoshandiswa kushandira kushandira vatengi zvikumbiro kumaseva eGoogle.

Pakati peakakosha maitiro eQuIC anomira pachena ndeaya:

  • Kuchengetedzwa kwepamusoro, kwakafanana neTLS (kutaura zvazviri, QUIC inopa kugona kushandisa TLS pamusoro peUDP)
  • Kuyerera kwekuvimbika kudzora kunodzivirira kurasika kwepaketi
  • Iko kugona kwekubatanidza kubatana ipapo (0-RTT, mune ingangoita 75% yematambudziko, dhata dzinogona kuendeswa nekukurumidza mushure mekutumira yekubatanidza setup packet) uye nekuona kushomeka kunonoka pakati pekutumira chikumbiro uye kugamuchira mhinduro (RTT, Round Rwendo Nguva)
  • Kwete kushandisa imwecheteyo nhamba yekuteedzana kana uchidzosera pakiti, iyo inodzivirira kusanzwisisika pakusarudza mapaketi akagashirwa uye kubvisa nguva dzekumirira
  • Kurasikirwa nepaketi kunokanganisa kuendeswa kwerukova chete rwunoenderana narwo uye hakumise kuendesa kwedata munzizi dzinofambiswa zvakafanana pamusoro pechizvino kubatana
  • Zvikanganiso zvekururamisa maturusi ayo anoderedza kunonoka nekuda kwekutamisazve kwemapaketi akarasika.
  • Iko kushandiswa kweakakosha mapaketi-chikamu kukanganisa kukanganisa kodhi kudzora mamiriro ezvinhu anoda kudzoserwa kweakarasika mapaketi data.
  • Iyo miganho yecryptographic yemabhuroko inoenderana nemipimo yemapaketi eQuIC, ichideredza mhedzisiro yekurasikirwa kwepaketi pakumisikidzwa kwezvirimo mumapakeji anotevera
  • Hapana matambudziko nekuvhara iyo TCP mutsara
  • Tsigiro yekubatanidza chinongedzo, iyo inoderedza nguva yekumisazve kubatanidza kwevatyairi mbozha
  • Kugona kubatanidza epamberi nzira dzekudzivirira kubatana kwakawanda

Izvo zvakare zvakasimbiswa kuti inoshandisa iko kwehunyanzvi hwekufanofungidzira bandwidth munzira imwe neimwe kuve nechokwadi chakaringana kurongedza kwepaketi kusimba, kuchidzivirira kubva kusvika padanho rekusangana umo kurasikirwa kwepaketi kunoonekwa;

Naizvozvowo kunoshamisa kuita uye kuita kunowanikwa pamusoro peTCP. Kune evhidhiyo masevhisi seYouTube, QUIC yakaratidza kudzikiswa kwemakumi matatu muzana mukudzokorodza mashandiro kana uchiona mavhidhiyo.

Iyo HTTP / 3 protocol inomisikidza kushandiswa kweQuIC sekufambisa kweHTTP / 2. Kugonesa HTTP / 3 uye iyo QUIC vhezheni ye23 dhizaini IETF yakatarwa, Chrome inofanira kumhanyisa pamwe nesarudzo "- inogoneka-quic - quic-vhezheni = h3-23" uyezve kana iyo quic test saiti ichivhurwa .rocks: 4433 in network yekuongorora modhi mune ekuvandudza maturusi, HTTP / 3 chiitiko chinoratidza se "http / 2 + quic / 99".

Zvichienzaniswa nepaketi rakaraswa neyakafanana HTTP kubatana, chete 1 pane mazhinji akabatana anomiswa, zvinoreva kuti QUIC inogona kutsigira kunze-kwe-kuendesa dhizaini kuti rakarasika packet rive shoma maitiro.

Si iwe unoda kuziva zvakawanda nezvazvo nezve izvi, unogona kubvunza chinotevera chinongedzo.


Izvo zviri muchinyorwa zvinoomerera pamisimboti yedu ye tsika dzekunyora. Kuti utaure chikanganiso tinya pano.
