Lub latency ntawm kev sib txuas hauv network sawv cev rau lub sijhawm xav tau rau cov ntaub ntawv taug kev ntawm tus neeg xa khoom thiab tus txais. Txawm hais tias txhua lub khoos phis tawj hauv computer muaj qee yam ntawm latency, tus nqi sib txawv thiab tuaj yeem nce ntxiv rau ntau yam laj thawj. Tib neeg pom cov sijhawm tsis xav txog ncua sijhawm li "lag."
latency siab kuj tuaj yeem ua rau qeeb qeeb. Piv txwv li, koj qhov kev ua si video yuav muaj kev latency siab, uas ua rau qhov kev ua si khov rau lub sijhawm thiab tsis xa cov hloov tshiab nyob ntawm lwm tus players. Kev ncua tsawg dua txhais tau tias qhov kev sib txuas tau ntsib qis dua latency.
Network lag tshwm sim rau ob peb lub laj thawj, xws li kev ncua deb thiab congestion. Qee zaum, koj tuaj yeem kho internet lag luam los ntawm kev hloov koj lub cuab yeej cuam tshuam nrog lub network li cas.
Latency thiab Bandwidth
Latency thiab bandwidth muaj feem cuam tshuam zoo tab sis yog ob nqe lus sib cais. Yuav kom nkag siab tias dab tsi ua rau muaj kev latency siab, nws yog ib qho tseem ceeb uas yuav tsum paub qhov txawv ntawm qhov bandwidth siab.
Yog tias koj qhov kev sib txuas hauv is taws nem tau piav qhia raws li cov yeeb nkab nqa cov ntaub ntawv, bandwidth yuav xa mus rau lub cev loj ntawm cov yeeb nkab. Cov yeeb nkab me me (tsawg bandwidth) tsis tuaj yeem tuav cov ntaub ntawv ntau ib zaug, thaum lub tuab tuab (siab bandwidth) tuaj yeem xa cov ntaub ntawv ntau dua ib zaug. Bandwidth feem ntau ntsuas hauv Mbps.
Latency yog ncua, ntsuas hauv ms. Nws yog lub sijhawm nws yuav siv cov ntaub ntawv txav los ntawm ib kawg ntawm cov yeeb nkab mus rau lwm qhov. Nws tseem hu ua tus nqi ping.
Kev nrawm ntawm lub teeb ntawm lub computer network
Tsis muaj kev sib txuas hauv network tuaj yeem mus nrawm dua li lub teeb nrawm. Hauv ib lub tsev lossis hauv cheeb tsam network, qhov kev ncua deb ntawm cov khoom siv me me uas lub teeb nrawm tsis muaj teeb meem. Txawm li cas los xij, rau kev sib txuas hauv internet, nws dhau los ua qhov tseem ceeb.
Raws li cov xwm txheej zoo tag nrho, lub teeb xav tau kwv yees li 5 ms taug kev 1,000 mais (kwv yees li 1,600 mais). Tsis tas li ntawd, feem ntau cov tsheb thauj mus los hauv is taws nem nyob deb tau hla cov kab hluav taws xob, uas tsis tuaj yeem nqa cov teeb liab sai li lub teeb vim yog lub hauv paus ntsiab lus ntawm physics hu ua refraction. Cov ntaub ntawv dhau ntawm fiber ntau optic cable, piv txwv li, yuav tsum muaj tsawg kawg yog 7.5 ms mus ncig 1,000 mais.
Kev sib txuas hauv Is Taws Nem Latencies
Dhau li qhov txwv ntawm physics, ntxiv latency network yog tshwm sim thaum kev khiav tsheb khiav los ntawm cov servers thiab lwm yam khoom siv qaum. Lub sijhawm latency ntawm kev sib txuas hauv internet kuj txawv nyob ntawm nws hom.
Txoj kev tshawb fawb ntsuas Broadband America (tshaj tawm thaum lig 2018) tau tshaj tawm cov kev sib txuas hauv internet latencies rau ntau hom kev pabcuam hauv Teb Chaws Asmeskas:
- Fiber optic: 12-20ms
- Cable internet: 15-34 ms
- DSL: 25-80 ms
- Satellite internet: 594-612 ms
Yuav ua li cas kho latency
Latency tuaj yeem hloov pauv me me ntawm ib feeb mus rau tom ntej, tab sis qhov kev lag luam ntxiv los ntawm kev nce me me tuaj yeem pom tau. Cov hauv qab no yog cov laj thawj feem ntau rau kev lag luam internet, qee qhov uas tsis muaj kev tswj hwm koj li:
-
Hloov lossis ntxiv lub router. Ib lub router thaum kawg bogs down yog tias ntau tus neeg siv khoom siv tib lub sijhawm. Kev sib cav sib ceg ntawm ntau tus neeg siv khoom txhais tau hais tias cov neeg siv khoom qee zaum tos rau ib leeg qhov kev thov kom ua tiav, ua rau muaj kev lag luam. Txhawm rau kho qhov no, hloov lub router nrog tus qauv muaj zog dua, lossis ntxiv lwm lub router rau lub network txhawm rau txo qhov teeb meem no.
Ib yam li ntawd, kev sib cav sib ceg tshwm sim ntawm qhov chaw nyob qhov kev sib txuas rau tus neeg muab kev pab cuam hauv is taws nem yog saturated nrog tsheb.
- Tsis txhob rub tawm ib txhij. Nyob ntawm qhov ceev ntawm koj qhov kev sib txuas, zam ntau dhau kev rub tawm ib txhij thiab kev sib tham hauv online kom txo qis lag.
-
Tsis txhob siv ntau daim ntawv thov ib zaug. PCs thiab lwm cov neeg siv khoom siv los ua ib qho kev lag luam network yog tias tsis tuaj yeem ua cov ntaub ntawv network sai. Thaum cov khoos phis tawj niaj hnub no muaj zog txaus nyob rau ntau lub sijhawm, cov khoom siv tuaj yeem qeeb yog tias muaj ntau daim ntawv thov khiav ib txhij. Yog tias koj xav tias koj muaj ntau qhov kev pab cuam qhib, kaw ob peb.
Khiav cov ntawv thov uas tsis tsim cov tsheb khiav hauv lub network tuaj yeem ua rau muaj kev lag luam. Piv txwv li, ib qho kev ua haujlwm tsis zoo tuaj yeem haus tag nrho cov CPU muaj, uas ua rau lub khoos phis tawj qeeb ntawm kev ua haujlwm network rau lwm yam kev siv. Yog tias qhov kev zov me nyuam tsis teb, yuam kom kaw.
- Tshawb xyuas thiab tshem tawm malware. Lub network kab mob hijacks lub khoos phis tawj thiab nws lub network interface, uas tuaj yeem ua rau nws ua haujlwm qeeb, zoo ib yam li overloaded. Khiav antivirus software ntawm cov khoom siv txuas nrog lub network kuaj pom thiab tshem tawm cov kab mob no.
- Siv kev sib txuas nrog tsis siv wireless. Online gamers, piv txwv li, feem ntau nyiam khiav lawv cov khoom siv los ntawm wired Ethernet es tsis txhob Wi-Fi vim Ethernet txhawb qis latencies. Thaum cov nyiaj khaws cia feem ntau tsuas yog ob peb milliseconds hauv kev xyaum, kev sib txuas hauv xov tooj kuj tseem zam qhov kev pheej hmoo ntawm kev cuam tshuam uas tuaj yeem ua rau muaj kev lag luam loj.
-
Siv cov cache hauv zos. Ib txoj hauv kev los txo qis latency yog siv caching hauv koj tus browser, uas yog ib txoj hauv kev rau qhov kev pab cuam khaws cov ntaub ntawv siv tsis ntev los no kom koj tuaj yeem nkag mus rau cov ntaub ntawv hauv zos rau lwm zaus koj thov cov ntaub ntawv los ntawm qhov chaw (tsis muaj download tau).
Feem ntau browsers cache cov ntaub ntawv los ntawm lub neej ntawd, tab sis yog tias koj rho tawm browser cache ntau dhau lawm, nws yuav siv sijhawm ntev dua los thauj cov nplooj ntawv qub uas koj nyuam qhuav mus xyuas.
Lwm Yam Uas Muaj Teeb Meem latency
Qee qhov teeb meem latency tuaj yeem kho tau, tab sis cov hauv qab no yog cov teeb meem latency uas feem ntau tsis nyob hauv koj txoj cai.
Tsheb thauj mus los
Spikes hauv internet siv thaum lub sij hawm siv siab tshaj plaws ntawm ib hnub feem ntau ua rau lag. Qhov xwm txheej ntawm qhov lag luam no txawv ntawm qhov chaw muab kev pabcuam thiab thaj chaw. Lwm yam tshaj li tsiv chaw lossis hloov kev pabcuam hauv internet, ib tus neeg siv tsis tuaj yeem zam kev lag luam zoo li no.
Daim Ntawv Thov Online Load
Online multiplayer games, websites, thiab lwm cov neeg siv-server network daim ntawv thov siv sib koom internet servers. Yog tias cov servers no dhau los ua haujlwm dhau los, cov neeg siv khoom muaj kev lag luam.
Wireless cuam tshuam
Satellite, ruaj ruaj wireless broadband, thiab lwm yam kev sib txuas hauv internet wireless tau raug teeb liab cuam tshuam los ntawm nag. Kev cuam tshuam wireless ua rau cov ntaub ntawv hauv lub network raug cuam tshuam hauv kev thauj mus los, ua rau qeeb los ntawm kev xa rov qab qeeb.
Lag Switches
Qee tus neeg uas ua si hauv online nruab ib lub cuab yeej hu ua lag luam ntawm lawv lub network hauv zos. Ib qho kev hloov pauv cuam tshuam cov teeb liab hauv lub network thiab qhia txog kev ncua ntawm cov ntaub ntawv rov qab mus rau lwm tus gamers txuas nrog kev sib tham nyob. Koj tuaj yeem ua me ntsis los daws qhov teeb meem lag luam no uas tsis yog zam kev ua si nrog cov neeg siv cov keyboards lag luam.
Npau Ntsuag Ntau Ntau?
Qhov cuam tshuam ntawm kev lag luam nyob ntawm seb koj ua dab tsi hauv lub network thiab, rau qee qhov, theem ntawm kev ua haujlwm hauv network uas koj tau loj hlob tuaj.
Cov neeg siv xov tooj cua hauv internet cia siab tias ntev latencies thiab zoo li tsis pom qhov lag luam ib ntus ntxiv ntawm 50 lossis 100 ms. Dedicated online gamers, ntawm qhov tod tes, nyiam lawv cov kev sib txuas hauv network kom khiav nrog tsawg dua 50 ms ntawm latency thiab sai sai pom ib qho lag luam saum toj no.
Feem ntau, cov ntawv thov online ua tau zoo tshaj plaws thaum lub network latency nyob qis dua 100 ms; ib qho kev lag luam ntxiv yog pom tau rau cov neeg siv.
