Vula umthombo womdlalo welifu kwiWebRTC: p2p, abadlali abaninzi, zero latency

Isoftware njengenkonzo, iziseko zophuhliso njengenkonzo, iqonga njengenkonzo, iqonga lonxibelelwano njengenkonzo, inkomfa yevidiyo njengenkonzo, kuthekani ngemidlalo yelifu njengenkonzo? Sele kukho iinzame ezininzi zokwenza umdlalo welifu (i-Cloud Gaming), efana neStadia, esandula ukusungulwa nguGoogle. Stadia ayintshanga kwiWebRTC, kodwa ngaba abanye bangasebenzisa iWebRTC ngendlela efanayo?

U-Thanh Nguyen uthathe isigqibo sokuvavanya eli thuba kwiprojekthi yakhe yomthombo ovulekileyo we-CloudRetro. CloudRetro isekwe kwiPion, ethandwayo Ithala leencwadi leWebRTC esekwe kwiGo (enkosi Ibonisiwe ukusuka kwiqela lophuhliso lwePion ngoncedo lwabo ekulungiseleleni eli nqaku). Kweli nqaku, u-Thanh unika inkcazo yoyilo lweprojekthi yakhe, kwaye uthetha malunga nokuba zeziphi izinto eziluncedo azifundileyo kunye nemingeni adibana nayo ngexesha lomsebenzi wakhe.

ukungena

Kunyaka ophelileyo, xa uGoogle ebhengeza iStadia, yabetha ingqondo yam. Lo mbono ukhethekile kwaye uvelisa izinto ezintsha kangangokuba bendihlala ndizibuza ukuba kwenzeka njani na ngetekhnoloji ekhoyo. Umnqweno wokuqonda ngcono esi sihloko undibangele ukuba ndenze inguqulelo yam yomdlalo welifu ovulelekileyo. Isiphumo saba simnandi nje. Ngezantsi ndingathanda ukwabelana ngenkqubo yokusebenza kunyaka wam iprojekthi.

I-TLDR: inguqulelo yesilayidi esifutshane esinamagqabantshintshi

Kutheni imidlalo yamafu ikamva

Ndiyakholelwa ukuba i-Cloud Gaming kungekudala iza kuba sisizukulwana esilandelayo semidlalo kuphela, kodwa nezinye iindawo zesayensi yekhompyuter. Umdlalo welifu yeyona nto iphambili yomxhasi/imodeli yomncedisi. Lo mzekelo ukhulisa umva wolawulo kwaye unciphise umsebenzi we-frontend ngokubamba i-logic yomdlalo kwi-server ekude kunye nokusasaza imifanekiso / i-audio kumthengi. Umncedisi wenza umsebenzi onzima ukuze umxhasi akasekho kwinceba yokunciphisa i-hardware.

I-Google Stadia ikuvumela ukuba udlale AAA imidlalo (okt imidlalo ye-blockbuster ephezulu) kwi-interface efana ne-YouTube. Indlela efanayo inokusetyenziswa kwezinye izicelo ezinzima ngaphandle kweintanethi ezifana nenkqubo yokusebenza okanye i-2D/3D uyilo lwegraphic, njl. ukuze sikwazi ukuziqhuba ngokungaguqukiyo kwizixhobo ezisezantsi kwiiplatifti ezininzi.

Ikamva lale teknoloji: Khawufane ucinge ukuba iMicrosoft Windows 10 isebenza kwisiphequluli seChrome?

Imidlalo yamafu ingumceli mngeni ngokobuchwephesha

Ukudlala yenye yezo ndawo zinqabileyo apho rhoqo, impendulo yomsebenzisi ekhawulezayo ifuneka. Ukuba ngamanye amaxesha sidibana nokulibaziseka kwemizuzwana emi-2 xa ucofa kwiphepha, oku kwamkelekile. Imijelo yevidiyo ephilayo idla ngokuhlala imizuzwana embalwa, kodwa ibonelela ngokusebenziseka okufanelekileyo. Nangona kunjalo, ukuba umdlalo uhlala uhleli nge-500ms, awudlaleki. Injongo yethu kukufezekisa i-latency ephantsi kakhulu ukwenzela ukuba i-gap phakathi kwegalelo kunye nemidiya ibe yincinci kangangoko. Ke ngoko, indlela yemveli yokusasaza ividiyo ayisebenzi apha.

  Kungakhathaliseki ukuba i-algorithm yoxinzelelo kunye nekhowudi iphuculwe kangakanani, inethiwekhi isesona sigqibo esenza igalelo kakhulu kwi-latency. Uyilo kufuneka lube nesixhobo sokudibanisa umncedisi okufutshane nomsebenzisi ukunciphisa ixesha lokuya nokubuya (RTT). Uyilo kufuneka lube nomnxibelelanisi omnye kunye neeseva ezininzi zokusasaza ezisasazwa kwihlabathi liphela: i-US West, i-US East, iYurophu, iSingapore, iChina. Zonke iiseva zostrimisho kufuneka zibe zodwa ngokupheleleyo. Inkqubo inokulungelelanisa ukuhanjiswa kwayo xa umncedisi ejoyina okanye eshiya inethiwekhi. Ke, ngetrafikhi enkulu, ukongeza iiseva ezongezelelweyo kuvumela ukukala okuthe tye.

  4. Ukuhambelana kwebhrawuza
  Imidlalo yamafu yeyona ilungileyo xa ifuna ubuncinci kubasebenzisi. Oku kuthetha ukuba kunokwenzeka ukuba usebenze kwisikhangeli. Abakhangeli banceda ukwenza amava okudlala akhululeke kangangoko kunokwenzeka kubasebenzisi, bewagcina ekufakeni isoftware kunye nehardware. Iibrowser zikwanceda ukubonelela ngokusebenza kweplatform phakathi kweenguqulelo zeselfowuni kunye nedesktop. Ngethamsanqa, iWebRTC ixhaswa kakuhle kwiibhrawuza ezahlukeneyo.

  5. Ukwahlula okucacileyo kojongano lomdlalo kunye nenkonzo
  Ndijonga inkonzo yokudlala ilifu njengeqonga. Wonke umntu kufuneka akwazi ukudibanisa nantoni na kwiqonga. Ngoku ndidibanise LibRetro ngenkonzo yokudlala ilifu kuba iLibRetro ibonelela ngojongano oluhle lomdlalo we-emulator kwimidlalo ye-retro efana neSNES, GBA, PS.

  6. Amagumbi omdlalo wabadlali abaninzi, umdlalo wezihlwele kunye nokudibanisa kwangaphandle (i-deep-link) kunye nomdlalo
  I-CloudRetro ixhasa imidlalo emininzi emitsha efana neCrowdPlay kunye ne-Intanethi yabadlali abaninzi kwimidlalo ye-retro. Ukuba abasebenzisi abaninzi bavula ikhonkco elinzulu elifanayo kwiikhompyuter ezahlukeneyo, baya kubona umdlalo ofanayo obalekayo kwaye baya kuba nakho ukuwujoyina.

  Ngaphezu koko, iindawo zomdlalo zigcinwa kwindawo yokugcina ilifu. Oku kuvumela abasebenzisi ukuba baqhubeke nokudlala nangaliphi na ixesha kuso nasiphi na esinye isixhobo.

  7. Ukulinganisa okuthe tye
  Njengayo nayiphi na i-SAAS kule mihla, umdlalo welifu kufuneka uyilwe ukuba unyuke ngokuthe tye. Uyilo lomnxibelelanisi-umsebenzi lukuvumela ukuba wongeze abasebenzi abaninzi ukuze bakhonze ngakumbi i-traffic.

  8. Akukho xhulumaniso kwilifu elinye
  Isiseko se-CloudRetro sibanjwe kubaboneleli belifu abahlukeneyo (i-Digital Ocean, i-Alibaba, umboneleli wesiko) kwimimandla eyahlukeneyo. Ndivumela ukuba usebenze kwisikhongozeli se-Docker kwisiseko kwaye uqwalasele useto lwenethiwekhi usebenzisa iskripthi se-bash ukunqanda ukutshixelwa kumnikezeli welifu omnye. Ngokudibanisa oku kunye ne-NAT Traversal kwiWebRTC, sinokuba bhetyebhetye wokuhambisa i-CloudRetro nakweliphi na iqonga lelifu kunye nakuwo nawuphi na umatshini womsebenzisi.

  Uyilo lwezakhiwo

  Umsebenzi: (okanye iseva yostrimisho ekhankanywe ngasentla) iphinda-phinda imidlalo, iqhuba umbhobho wekhowudi, kwaye isasaze imidiya ekhowudiweyo kubasebenzisi. Iimeko zabasebenzi zisasazwa kwihlabathi liphela, kwaye umsebenzi ngamnye unokusingatha iiseshini zabasebenzisi ezininzi ngaxeshanye.

  Umnxibelelanisi: unoxanduva lokudibanisa umsebenzisi omtsha kunye noyena msebenzi ufanelekileyo wokusasaza. Umnxibelelanisi unxibelelana nabasebenzi ngeWebSocket.

  Uyilo oluphezulu lwe-CloudRetro

  Ushicilelo lweSiko

  Xa umsebenzisi omtsha evula i-CloudRetro kumanyathelo 1 kunye ne-2 aboniswe kumzobo ongezantsi, umququzeleli kunye noluhlu lwabasebenzi abakhoyo bayacelwa kwiphepha lokuqala. Emva koku, kwinyathelo lesi-3 umxhasi ubala ukulibaziseka kwabo bonke abaviwa usebenzisa isicelo se-ping ye-HTTP. Olu luhlu lokulibaziseka luthunyelwa emva kumququzeleli ukuze abone oyena msebenzi ufanelekileyo ukuba akhonze umsebenzisi. Inyathelo lesi-4 ngezantsi lidala umdlalo. Uqhagamshelo losasazo lweWebRTC lusekiwe phakathi komsebenzisi kunye nomsebenzi owabelweyo.
  
  Iskripthi somsebenzisi emva kokufumana ukufikelela

  Yintoni ngaphakathi emsebenzini

  Imibhobho yomdlalo kunye nokusasaza igcinwa ngaphakathi komsebenzi ngokuzimeleyo kunye nokutshintshiselana ngolwazi apho ngojongano. Okwangoku, olu nxibelelwano lwenziwa ngokudlulisela idatha kwimemori nge Iitshaneli zeGolang kwinkqubo efanayo. Injongo elandelayo kukuhlukana, okt. ukuqaliswa okuzimeleyo komdlalo kwenye inkqubo.

  
  Ukusebenzisana kwamacandelo abasebenzi

  Amalungu aphambili:

  • I-WebRTC: icandelo lomxhasi elamkela igalelo lomsebenzisi kunye nemveliso yemidiya ekhowudiweyo evela kumncedisi.
  • Isilinganisi somdlalo: icandelo lomdlalo. Ngombulelo kwilayibrari ye-Libretro, inkqubo iyakwazi ukuqhuba umdlalo ngaphakathi kwenkqubo efanayo kunye ne-internal intercept media kunye ne-input stream.
  • Izakhelo zomdlalo zibanjwa kwaye zithunyelwe kwi-encoder.
  • Umfanekiso/Isifakeli khowudi somsindo: umbhobho wekhowudi ethatha izakhelo zemidiya, ifake iikhowudi ngasemva, kwaye ikhuphe imifanekiso ekhowudiweyo/umsindo.

  Ukuphunyezwa

  I-CloudRetro ixhomekeke kwiWebRTC njengetekhnoloji yomqolo wayo, ke ngaphambi kokuntywila kwiinkcukacha zokuphunyezwa kweGolang, ndigqibe kwelokuba ndithethe ngeWebRTC ngokwayo. Le teknoloji emangalisayo eye yandinceda kakhulu ekufezekiseni i-latency ye-sub-second yokusasaza idatha.

  WebRTC

  IWebRTC yenzelwe ukubonelela ngonxibelelwano olukumgangatho ophezulu kontanga-kuontanga kwii-apps zomthonyama zomthonyama kunye nezikhangeli zisebenzisa ii-API ezilula.

  Ukuhanjiswa kweNAT

  I-WebRTC yaziwa ngokusebenza kwayo kwe-NAT Traversal. IWebRTC yenzelwe unxibelelwano lwabalingane. Injongo yayo kukufumana eyona ndlela ifanelekileyo ethe ngqo, ukunqanda amasango e-NAT kunye ne-firewall yokunxibelelana koontanga ngenkqubo ebizwa. ICE. Njengenxalenye yale nkqubo, iWebRTC APIs ifumana idilesi kawonke-wonke ye IP usebenzisa abancedisi be STUN kwaye bayigqithisele kumncedisi wodluliselo (JIKA) xa udibaniso oluthe ngqo lungenakusekwa.

  Nangona kunjalo, i-CloudRetro ayilisebenzisi ngokupheleleyo eli nqaku. Unxibelelwano lontanga-kwintanga alukho phakathi kwabasebenzisi, kodwa phakathi kwabasebenzisi kunye neeseva zefu. Icala lomncedisi wemodeli linezithintelo ezimbalwa zonxibelelwano oluthe ngqo kunesixhobo esiqhelekileyo somsebenzisi. Oku kukuvumela ukuba uvule kwangaphambili amazibuko angenayo okanye usebenzise iidilesi zikawonke-wonke ze-IP ngokuthe ngqo, kuba umncedisi akakho emva kwe-NAT.

  Ngaphambili, bendifuna ukuguqula iprojekthi ibe liqonga lokusasaza umdlalo kwi-Cloud Gaming. Umbono yayikukuvumela abadali bemidlalo ukuba babonelele ngemidlalo kunye nezixhobo zokusasaza. Kwaye abasebenzisi baya kusebenzisana nababoneleli ngokuthe ngqo. Ngale ndlela yokwabela amagunya, i-CloudRetro sisikhokelo nje sokuqhagamshela izixhobo zokusasaza zomntu wesithathu kubasebenzisi, iyenza ibe nzima ngakumbi xa ingasabanjwa. Indima yeWebRTC NAT Traversal apha ibaluleke kakhulu ukuququzelela uxhulumaniso lontanga-to-peer ukuqaliswa kwimithombo yokusasaza yomntu wesithathu, okwenza kube lula kumdali ukuba axhumeke kwinethiwekhi.

  Uxinzelelo lwevidiyo

  Uxinzelelo lwevidiyo yinxalenye eyimfuneko yombhobho kwaye inegalelo elikhulu ekuhambeni kakuhle. Ngelixa kungeyomfuneko ukwazi zonke iinkcukacha zeVP8/H264 encoding yevidiyo, ukuqonda iikhonsepthi kunokukunceda uqonde iinketho zesantya sevidiyo yokusasaza, ukulungisa isimilo esingalindelekanga, kwaye uhlengahlengise ukubambezeleka.

  Ukucinezela ividiyo yenkonzo yokusasazwa ngumngeni kuba i-algorithm kufuneka iqinisekise ukuba ixesha elipheleleyo lokufaka ikhowudi + ixesha lokuhambisa inethiwekhi + ixesha lokudibanisa liphantsi kangangoko. Ukongeza, inkqubo yokubhalwa kweekhowudi kufuneka ihambelane kwaye iqhubeke. Olunye urhwebo lwekhowudi alusebenzi—umzekelo, asinakukhetha amaxesha amade eekhowudi ngaphezu kobungakanani beefayile ezincinci kunye namaxesha okuguqula iikhowudi, okanye sisebenzise ucinezelo olungangqinelaniyo.

  Umbono emva koxinzelelo lwevidiyo kukuphelisa amasuntswana olwazi olungeyomfuneko ngelixa ugcina inqanaba elamkelekileyo lokuchaneka kubasebenzisi. Ukongeza kwi-encoding yezakhelo zemifanekiso emileyo yomntu ngamnye, i-algorithm ifaka isakhelo sangoku ukusuka kweyangaphambili nezilandelayo, ngoko ke umahluko wabo kuphela uthunyelwa. Njengoko kunokubonwa kumzekelo kunye nePacman, kuphela ngamanqaku ahlukeneyo ahanjiswayo.

  
  Ukuthelekiswa kwezakhelo zevidiyo usebenzisa iPacman njengomzekelo

  Uxinzelelo lomsindo

  Ngokunjalo, i-algorithm yoxinzelelo lomsindo ishiya idatha engenakuqondwa ngabantu. Okwangoku i-Opus yeyona codec iqhuba kakuhle kakhulu. Yenzelwe ukuhambisa i-audio wave phezu kweprotocol elandelwayo yedathagram efana ne-RTP (iProtokholi yoThutho lweXesha lokwenyani). I-latency yayo iphantsi kune-mp3 kunye ne-aac, kwaye umgangatho uphezulu. I-latency ihlala ijikeleze i-5 ~ 66,5ms.

  I-Pion, iWebRTC eGolang

  Inkqantosi yiprojekthi yomthombo ovulekileyo ezisa iWebRTC kwiGolang. Endaweni yokusongwa okuqhelekileyo kwamathala eencwadi e-C++ eWebRTC, iPion yinzalelwane yaseGolang yokuphunyezwa kweWebRTC ngokusebenza okungcono, ukudityaniswa kweGo, kunye nolawulo loguqulelo kwiiprothokholi zeWebRTC.

  Ithala leencwadi likwavumela ukusasazwa kwezinto ezininzi ezakhelwe ngaphakathi kunye ne-sub-second latency. Inokuphunyezwa kwayo kwe-STUN, DTLS, SCTP, njl. kunye neminye imifuniselo nge-QUIC kunye neWebAssembly. Eli thala leencwadi elivulelekileyo ngokwalo sisixhobo esihle sokufunda esinamaxwebhu agqwesileyo, ukuphunyezwa kweprotocol yenethiwekhi, kunye nemizekelo epholileyo.

  Ukubhala i-CloudRetro kwi-Golang

  
  Ukuphunyezwa komsebenzi kwi-Go

  Yiya kwi-Action Channels

  Enkosi kuyilo oluhle lwetshaneli yeGo, iingxaki zokusasaza umsitho kunye neconcurrency zenziwe lula kakhulu. Njengomzobo, iiGoRoutines ezahlukeneyo zineenxalenye ezininzi ezisebenza ngokunxuseneyo. Icandelo ngalinye lilawula imeko yalo kwaye linxibelelana ngamajelo. Ubango olukhethiweyo lukaGolang lunyanzelisa isiganeko esinye seathom ukuba siqwalaselwe ngalo lonke ixesha kumdlalo (uphawu lomdlalo). Oku kuthetha ukuba akukho lutshixo lufunekayo kolu yilo. Umzekelo, xa umsebenzisi egcina, i-snapshot epheleleyo yesimo somdlalo siyafuneka. Le meko kufuneka ihlale iqhubekile, ingena de ugcino lugqitywe. Ngexesha lomdlalo ngamnye wokuphawula, i-backend inokusingatha kuphela ukugcinwa okanye ukusebenza kwegalelo, ukwenza inkqubo yenkqubo ikhuseleke.

  func (e *gameEmulator) gameUpdate() {
  for {
  	select {
  		case <-e.saveOperation:
  			e.saveGameState()
  		case key := <-e.input:
  			e.updateGameState(key)
  		case <-e.done:
  			e.close()
  			return
  	}
      }
  }

  Umlandeli-ngaphakathi/Fan-out

  Le template yeGolang ilingana neCrowdPlay yam kunye neMidlalo emininzi yokusetyenziswa ngokugqibeleleyo. Ukulandela le pateni, onke amagalelo omsebenzisi kwigumbi elinye akhelwe kumjelo ophakathi wokungena. Imidiya yomdlalo isasazwa kubo bonke abasebenzisi kwigumbi elinye. Ngale ndlela, sifezekisa ulwahlulo lomdlalo phakathi kweeseshini ezininzi zomdlalo zabasebenzisi abohlukeneyo.

  
  Ungqamaniso phakathi kweeseshini ezahlukeneyo

  Ukungalungi kweGolang

  IGolang ayifezekanga. Ijelo liyacotha. Xa kuthelekiswa nokuthintela, itshaneli yeGo yindlela elula yokusingatha imisitho ehambelanayo kunye nentambo, kodwa itshaneli aliboneleli ngeyona ntsebenzo ibalaseleyo. Kukho ingqiqo yokuthintela entsonkothileyo phantsi kwetshaneli. Ke ndenze uhlengahlengiso ekuphunyezweni, ndifaka kwakhona izitshixo kunye namaxabiso eatom xa nditshintsha amajelo okuphucula ukusebenza.

  Ukongeza, umqokeleli wenkunkuma eGolang akalawulwa, nto leyo ngamanye amaxesha ibangela unqumamo olude ngokukrokrisayo. Oku kuphazamisa kakhulu usetyenziso lwexesha lokwenyani lokusasaza.
