Kakaretso ea kutloisiso

Latency ke nako e nkang hore data e fetisoe ho tloha sebakeng se seng ho ea ho se seng, ho tloha ho 15 milliseconds ho isa ho 44 milliseconds ho latela marang-rang. Leha ho le joalo, liprothokholo tse fapaneng li ka theola lebelo leo haholo ho millisecond e le 'ngoe feela. Liphello tsa nako e telele tsa ho fokotseha ha latency li ka kenyelletsa ho amoheloa ho eketsehileng ha likopo tse eketsehileng le tse bonahalang (AR / VR) le likoloi tse ikemetseng.

Boemo bo tšepahalang le bo tlase ba latency

Latency ke bothata ba lits'ebetso tse nang le likhokahano tsa nako ea nnete, joalo ka lipapali, 'nete ea sebele (VR), le seboka sa video. Palo ea lisebelisoa tsa marang-rang le molumo oa phetisetso ea data li ka lebisa ho eketseha ha linako tsa latency. Ho feta moo, liketsahalo tse ngata le batho ba itšetlehileng ka khokahanyo e haufi-ufi ba kentse letsoho litabeng tsa latency. Ho fokotsa nako ea phetiso ea data ho ke ke ha nolofatsa bophelo ba letsatsi le letsatsi feela; e tla boela e lumelle nts'etsopele ea bokhoni ba bohlokoa ba thekenoloji, joalo ka k'homphieutha ea bohale le ea maru. Tlhokahalo ea ho tsoela pele ho fumana li-latencies tse tlase le tse tšepahalang li lebisitse ho lipatlisiso tse ngata le lintlafatso meahong ea marang-rang.

E 'ngoe ea mehato e joalo ke ho ata ha marang-rang a mehala ea thelefono ea moloko oa bohlano (5G). Sepheo se ka sehloohong sa marang-rang a 5G ke ho eketsa bokhoni, sekhahla sa khokahanyo, le ho fumaneha ha marang-rang ha u ntse u ntlafatsa ho tšepahala le ho fokotsa latency. Ho laola likopo le lits'ebeletso tse ngata tsa ts'ebetso, 5G e nahana ka mekhahlelo e meraro ea mantlha ea litšebeletso: 

• Broadband e ntlafalitsoeng ea mohala (eMBB) bakeng sa litefiso tse phahameng tsa data, 
• puisano e kholo ea mofuta oa mochini (mMTC) ho lumella phihlello ho tsoa ho palo e eketsehang ea lisebelisoa, le 
• ultra-reliable and low latency communication (URLLC) bakeng sa lipuisano tsa bohlokoa-kholo. 

Ho thata ka ho fetisisa ho litšebeletso tse tharo ho kenya ts'ebetsong ke URLLC; Leha ho le joalo, tšobotsi ena e ka ba ea bohlokoa ka ho fetesisa ho ts'ehetsa li-automation tsa indasteri, tlhokomelo ea bophelo bo hole, le litoropo le matlo a bohlale.

Tšusumetso e senyang

Lipapali tsa libapali tse ngata, likoloi tse ikemetseng, le liroboto tsa feme li hloka latency e tlase haholo ho sebetsa ka mokhoa o sireletsehileng le ka nepo. 5G le Wi-Fi li entse li-milliseconds tse leshome ka mokhoa o itseng oa 'standard' bakeng sa latency. Leha ho le joalo, ho tloha ka 2020, bafuputsi ba Univesithi ea New York (NYU) ba ntse ba etsa lipatlisiso tsa ho fokotsa latency ho millisecond e le 'ngoe kapa ka tlase ho moo. Ho finyella sena, mokhoa oohle oa likhokahano, ho tloha qalong ho isa qetellong, o tlameha ho hlophisoa bocha. Pejana, baenjiniere ba ne ba ka hlokomoloha mehloli ea tieho e fokolang hobane ba ne ba sa ame haholo latency ka kakaretso. Leha ho le joalo, ho ea pele, bafuputsi ba tlameha ho theha mekhoa e ikhethang ea ho khouta, ho fetisa, le ho tsamaisa data ho felisa tieho e nyane.

Mekhoa le mekhoa e mecha e ntse e theoa butle-butle ho thusa ho lieha ho lieha. Mohlala, ka 2021, Lefapha la Ts'ireletso la US le ile la sebelisa maemo a Open Radio Access Network ho aha marang-rang a prototype a nang le sub-15 millisecond latency. Hape, ka 2021, CableLabs e thehile maemo a DOCSIS 3.1 (data-over-cable service interface) mme e phatlalalitse hore e netefalitse modem ea pele e lumellanang le DOCSIS 3.1. Nts'etsopele ena e bile mohato oa bohlokoa ho tlisa khokahanyo e tlase ea latency 'marakeng. 

Ho feta moo, litsi tsa data li ntse li sebelisa theknoloji e eketsehileng ea "virtualization" le "hybrid cloud cloud" ho ts'ehetsa lits'ebetso tse kenyelletsang ho phallela video, ho boloka le ho hlaphoheloa, lisebelisoa tsa lisebelisoa tsa komporo (VDI) le Marang-rang a Lintho (IoT). Ha lik'hamphani li fetohela ho bohlale ba maiketsetso le ho ithuta ka mochini (AI/ML) ho tsamaisa litsamaiso tsa tsona, li-latencies tse tšepahalang le tse tlase li ka lula li le ka pele ho matsete a theknoloji.

Litlamorao tsa latency e tšepahalang le e tlase

Litlamorao tse pharalletseng tsa latency e tšepahalang le e tlase e ka kenyelletsa: 

• Litlhahlobo tse hole tsa tlhokomelo ea bophelo bo botle, lits'ebetso, le liopereishene tse sebelisang liroboto tse thusang le 'nete e netefalitsoeng.
• Likoloi tse ikemetseng tse buisanang le likoloi tse ling ka litšitiso tse tlang le tšubuhlellano ea sephethephethe ka nako ea nnete, ka hona li fokotsa ho thulana. 
• Liphetolelo tsa hang-hang nakong ea mehala ea kopano ea video, ho etsa hore ho shebahale eka motho e mong le e mong o bua ka lipuo tsa basebetsi-'moho le bona.
• Ho nka karolo ho se nang moeli 'marakeng oa lichelete oa lefats'e, ho kenyeletsoa ho bolaoa ha khoebo ka potlako le matsete, haholo-holo ho chelete ea crypto.
• Baahi ba metaverse le VR ba na le litšebelisano le mesebetsi e potlakileng, ho kenyeletsoa litefo, libaka tsa mosebetsi, le lipapali tsa kaho ea lefatše.
• Litsi tsa thuto li amohela liphaposi tsa ho rutela tse qoelisoang ka ho fetesisa, tse tsamaisang boiphihlelo bo matla le bo hokahaneng ba thuto ho pholletsa le libaka.
• Katoloso ea meaho e bohlale ea litoropo, e nolofalletsang taolo e nepahetseng ea matla le polokeho e matlafalitsoeng ea sechaba ka tlhahlobo ea data ea nako ea nnete.

Lipotso tse lokelang ho nahanoa

• Li-latency tse tlase tsa Marang-rang li tla u thusa joang mesebetsing ea hau ea letsatsi le letsatsi?
• Ke mekhoa efe e meng ea theknoloji e tla thusa latency e tlase?
