Izwi latency rinoreva chero imwe yemhando dzakasiyana-siyana dzekunonoka zvinowanzoitika mukugadzirisa kwekunamata data. A low latency network connection ndiyo inosangana nenguva shomanana yekuderera, asi yakakwirira latency inoshungurudzwa kubva kunonoka kwenguva refu.
Kunze kwekuparidzirwa kunonoka, latency inogonawo kusanganisira kupedzisira kutengesa (zvivako zvemuviri wepanyama) nekugadzirisa kunonoka (zvakadai sekupfuura nemasevhisi proxy kana kuita mapurogiramu emagetsi paIndaneti).
Kunyangwe kufungidzira kwehutano nekukurumidza kunowanzozonzwisiswa se bandwidth , latency ndiyo imwe chinhu chinokosha. Zvisinei, sezvo munhu akawandisa ari kuzivikanwa nepfungwa ye bandwidth, nokuti ndiyo inoshambadzirwa nevagadziri vemakambani emichina, nyaya dzekugadzirisa zvakaenzana nekugadzirisa kushandiswa kwevashandi.
Latency vs. vs.put
Kunyange zvazvo nheyo yepamusoro bandwidth yehutano hwehutano yakagadzirirwa maererano nehutano inoshandiswa, iyo chaiyo yehuwandu inotenderera pamusoro payo (inonzi input ) inopesana nekufamba kwenguva uye inoshungurudzwa nepamusoro uye yakaderera latencies.
Kuwedzeredza latency kunobatanidza zvigadziri zvinodzivirira dambudziko kubva pakuzadza pipe pipe, nokudaro kuderedza kuputika uye kuvhara huwandu hwemagetsi ekubatanidza.
Izvozvo zvinokonzerwa ne latency pamusana pemitambo zvinogona kuva zvenguva pfupi (zvinogara kwemaminitsi mashomanana) kana kuti zvinoramba (zvinogara zvichienderana) zvichibva pakuderera kunonoka.
Latency yeInternet Services, Software, uye Devices
Pa DSL kana mutambo wekutengesa internet, latency yepasi pezana mamillisecond (ms) inowanzo uye pasi pe25 ms inowanzoita. NeStaneti internet connections, kune rumwe rutivi, inowanzo latency inogona kuva 500 ms kana kupfuura.
Nhare yekutengesa yakarongwa pa20 Mbps inogona kuita zvakanyanya kuipa kupfuura yevhisi yakarongwa pa 5 Mbps kana iri kutamba ne high latency.
Nhare yepaItaneti inotarisa inoratidza kusiyana pakati pe latency uye bandwidth pamakombiyuta. Satellite ine zvese mbiri yakakwirira bandwidth uye high latency. Paunenge uchitakura peji yepawebhu, somuenzaniso, vazhinji vanoshandisa sateresi vanogona kutarisa kunonoka kuoneka kubva panguva yavanopinda nekero kusvika panguva iyo peji inotanga kutakura.
Iyi yakakwirira latency inonyanya kukonzerwa nekuparidzika kunonoka sezvo mharidzo yekukumbira inofamba nekukurumidza kwechiedza kusvika kure necheterevhizheni nzvimbo uye kudzokera kumusha weimba . Kana kese mharidzo isvika paNyika, zvisinei, peji yacho inotakura nokukurumidza seyedzimwe yakakwirira-bandwidth internet connections (yakadai se DSL kana internet cable).
WAN latency imwe yerudzi rwe latency inogona kukonzerwa apo inetaneti iri kushingaira kuitisa nemotokari kusvika pane zvimwe zvikumbiro zvadaro zvinononoka sezvo hardware isingagoni kutora zvose zvayo paunowedzera. Izvi zvinokanganisa nhare yehutano zvakare kubva pakusungirirwa kwose kunoshanda pamwe chete.
Chikanganiso kana imwe dambudziko nehurdware inogona kuwedzera nguva inotora kuti iverenge data, iyo imwe chikonzero che latency. Izvi zvingava zvakadaro kune network network hardware kana kunyange hardware yedhidhiyo, seyenguva inotyisa motokari inotora nguva kuchengeta kana kuwana deta.
Izvo software inoshandiswa pamutambo inogona kukonzera latency zvakare. Mamwe mapurogiramu antivirus anoongorora ose data ari kubuda mukati uye kunze kwekombiyuta, iyo ndeyechokwadi chimwe chikonzero mamwe emakombiyuta akadzivirirwa ari kuderera kupfuura vamwe vavo. Nhoroondo yakatsvakurudzwa kazhinji inoparadzaniswa uye inoshandiswa isati yashandiswa.
Kuyera Network Latency
Network tools kana ping test uye traceroute chiyero latency kuburikidza nekugadza nguva inotora ruvara rwepaketetti kuti iende kubva kune imwe nzvimbo kuenda kune imwe nzvimbo, uye shure-inonzi nguva yekudzoka -nguva .
Kudzokorora nguva nguva haisi iyo chete nzira yekuyera latency asi ndiyo yakazara.
Quality of Service (QoS) zvinhu zvemusha uye mabhizimusi masangano akagadzirirwa kubatsira kutarisira zvose bandwidth uye latency pamwe chete kuti zvipe zvakanyanya kushanda.
