Mawu akuti latency amatanthauza mtundu uliwonse wa kuchedwa kumene kumachitika pakukonzekera kwa deta. Kugwiritsira ntchito pang'onopang'ono kugwiritsidwa ntchito pa Intaneti kumakhala ndi nthawi yochepa yochepetsera, pamene kulumikizana kwa latency kumakhala kochedwa kwambiri.
Kuwonjezera pa kufalitsa kufalikira, latency ingaphatikizepo kuchedwa kwapadera (katundu wa zowonongeka) ndi kuchepetsa kuchepetsa (monga kupyolera ma seva oyimira kapena kupanga ma intaneti pa intaneti).
Ngakhale malingaliro a intaneti ikufulumizitsa ndi kugwira ntchito nthawi zambiri amamveka ngati bandwidth , latency ndi chinthu china chofunikira. Komabe, popeza munthu wamba amakhala wodziwa bwino lingaliro la bandwidth, chifukwa ndilo lolengezedwa ndi opanga makina apakompyuta, nkhani za latency mofanana ndi zomwe akugwiritsa ntchito pomaliza.
Latency vs. Kupyolera
Ngakhale kuti chiwerengero chapamwamba cha kugwiritsidwa ntchito kwa intaneti chimakhazikitsidwa molingana ndi luso lamagetsi, mavoti omwe amatha kutuluka (otchedwa toput ) amasiyana ndi nthawi ndipo amakhudzidwa ndi latency ndi apansi latencies.
Kuchuluka kwa latency kumapangitsa kuti zipangizo zisazitse zodzaza pulogalamu yachonde, motero kuchepetsa kupititsa patsogolo ndi kuchepetsa kugwiritsidwa ntchito kwapadera kwagwirizano.
Zotsatira za latency pa kujambulidwa kwa intaneti zingakhale zosakhalitsa (kukhalapo kwa masekondi angapo) kapena kupitiriza (nthawi zonse) malingana ndi gwero la kuchedwa.
Kutha kwa Mapulogalamu a intaneti, Mapulogalamu, ndi Zida
Pa ma DSL kapena ma intaneti, ma latency osachepera 100 milliseconds (ms) ali ofanana ndipo osachepera 25 ms nthawi zambiri amatha. Pokhala ndi ma satelan maulumikizi, pambali ina, mawonekedwe ofanana akhoza kukhala 500 ms kapena apamwamba.
Utumiki wa intaneti womwe umawerengedwa pa 20 Mbps ukhoza kuwonetsa moipa kuposa ntchito yomwe ili pa 5 Mbps ngati ikuyenda ndi latency yapamwamba.
Utumiki wa intaneti pa satellite umasonyeza kusiyana pakati pa latency ndi bandwidth pa makompyuta. Satellite ili ndipamwamba kwambiri bandwidth ndi high latency. Mwachitsanzo, polemba tsamba lamasamba, ambiri omwe amagwiritsira ntchito satellita amatha kuchedwa pozindikira nthawi yomwe amalowa ku adiresi nthawi imene tsamba likuyamba.
Ulendo wamtali woterewu makamaka chifukwa cha kufalitsa kwachangu pamene uthenga wopempha umayenda pa liwiro lakutali kupita ku sitima ya satelanti komanso kubwerera ku nyumba . Momwe mauthengawa abwera pa Dziko lapansi, komabe tsambali likuthamanga mofulumira ngati mauthenga ena apamwamba a intaneti (monga DSL kapena intaneti).
WAN latency ndi mtundu wina wa latency umene ukhoza kuyambitsa pamene intaneti ikugwira ntchito ndi magalimoto mpaka pomwe zopempha zina zimachedwa nthawi yomwe hardware silingathe kuigwira zonsezi mofulumira. Izi zimakhudza intaneti yowongoleranso kuchokera pamene ukonde wonse ukugwira ntchito pamodzi.
Cholakwika kapena vuto lina la hardware lingapangitse nthawi yomwe imafunika kuti iwerenge deta, ndicho chifukwa china cha latency. Izi zingakhale choncho kwa hardware yachithunzithunzi kapena hardware ya chipangizo, monga pang'onopang'ono yovuta galimoto yomwe imatenga nthawi kusungira kapena kutenga deta.
Mapulogalamuwa akuyenda pa dongosolo angayambitsenso latency. Mapulogalamu ena a antivirus amafufuza zonse zomwe zikuyenda mkati ndi kunja kwa makompyuta, zomwe ziri chifukwa chimodzi chomwe ena amatetezera makompyuta amachepetserapo kusiyana ndi anzawo. Deta yosanthuledwa nthawi zambiri imagawanika ndi kusinthana isanagwiritsidwe ntchito.
Kuyeza Network Latency
Zida zamakono monga mayeso ndi zovuta zamtundu wa latency potengera nthawi yomwe imatenga pulogalamu yamtundu wapadera kuti ayende kuchokera ku gwero kupita kumalo, ndi kubwerera kumbuyo.
Nthawi yozungulira ulendo si njira yokhayo yoyezera latency koma ndi yofala kwambiri.
Zinthu za Service (QoS) zamagulu ndi zamalonda zimapangidwa kuti zithandizire kuyendetsa magulu onse awiri pamodzi ndikuthandizira kuti agwirizane kwambiri.
