Kuwala kwa Mawu Kumayambitsa Khokoza ndi Kumveka Kwachisoni
Latency ndi kuchedwa kapena kukumba mu chinachake. Mungathe kukhala ndi latency pa makompyuta komanso pa nthawi yolankhulirana. Ndizovuta kwambiri ndipo ndi vuto lalikulu pa kuyitana kwa mawu.
Latency ndi nthawi pakati pa mphindi yomwe paketi ya phokoso imafalitsidwa ndipo ikafika pamapeto pake, zomwe zimabweretsa kuchedwa ndikumangidwanso chifukwa cha zizindikiro zochepetsera . Chizoloŵezi ndichofunika kwambiri pa kulankhulana kwa VoIP pankhani ya kuyitana khalidwe.
Pali njira ziwiri zowonjezereka zimayesedwa: njira imodzi ndi ulendo wozungulira. Njira yotsatira latency ndiyo nthawi yomwe paketi ikuyendetsa njira imodzi kuchokera ku gwero kupita ku malo omwe akupita. Ulendo woyenda ulendo wotsiriza ndi nthawi yomwe imatenga paketi kuti ifike ndikupita komweko, kubwerera ku gwero. Ndipotu, si paketi yomweyo yomwe imabwerera mmbuyo, koma kuvomereza.
Latency imayesedwa milliseconds (ms), yomwe ili masekondi zikwi. Ulendo wa 20 ms ndi wodabwitsa kuti maitanidwe a IP ndi 150 ms sangathe kuoneka ndipo amavomereza. Komabe, zopambana kuposa izo ndi khalidwe zimayamba kuchepa; 300 ms kapena apamwamba ndipo sichilandiridwa kwathunthu.
Zindikirani: Kutseka kwa foni nthawi zina kumatchedwa kuchedwa pakamwa ndi khutu , ndipo latency audio latency audio imadutsanso ndi mawu ofunikira kapena QoE.
Zotsatira za Kufika pa Maitana a Voice
Izi ndi zotsatira zochepa chabe za zotsatira za latency pa khalidwe la kuyitana:
- Zimachepetsa kukambirana kwanu foni
- Kusakhazikika kungabweretse phokoso lophwanyidwa, ndi wokamba mmodzi akuphwanya china
- Zifukwa zimalimbikitsa
- Kusokoneza maganizo pakati pa mawu ndi mitundu ina ya deta, makamaka pa msonkhano wa mavidiyo
Mmene Mungathetse Kutha
Ili ndi ntchito yovuta ndipo imakufunsani kulingalira zinthu zingapo, zambiri zomwe simungathe kuzilamulira. Mwachitsanzo, simukusankha codecs imene wothandizira wanu amagwiritsa ntchito.
Nazi zinthu zomwe zimayambitsa VoIP latency:
- Mulibe bandwidth okwanira. Pamene intaneti ikuyenda pang'onopang'ono, mapaketi a deta amatenga nthawi yambiri kuti ayende uku ndi uku ndipo izi zimayambitsa kuyankhulana. Kawirikawiri, mapaketi amabwera mwadongosolo, zomwe zimapangitsa reassembly kusatheka kupatula ngati dongosolo libwezeretsedwa. Ichi ndi chimodzi mwa zovuta za kusintha kwa pakiti, yomwe VoIP imagwiritsa ntchito.
- Wowotcha moto wanu ukhoza kuletsa traffic. Kufufuza nthawi zonse kumakhala kovuta, kotero onetsetsani kuti mumalola kuti mapulogalamu anu a VoIP apitirize kulowa pulogalamu ya firewall .
- Ma codec olakwika akugwiritsidwa ntchito. Codecs ndi ndondomeko zomwe zimagwiritsidwa ntchito pophatikizapo zizindikiro zamankhwala ku deta yolumikizira pazithunzithunzi, ndipo wothandizira wanu akhoza kugwiritsa ntchito zolakwika, zomwe palibe chomwe mungachite. Komabe, ngati mukugwiritsa ntchito mapulogalamu a VoIP omwe amakulolani kuti mukhale ndi ma codecs, yesani kuwamasulira.
- Mukugwiritsa ntchito zipangizo zakale. Maofesi akale omwe ali ndi mapulogalamu atsopano kapena mawonekedwe atsopano sangagwire ntchito bwino ndipo amachedwetsa ndipo latency nthawi zambiri zimakhala zotsatira. Muyenera kuyesa kugwiritsa ntchito foni yamakono kapena foni yosiyana (ngati mukugwiritsa ntchito foni ya IP kapena china chilichonse cha VoIP). Chikhomo chanu chingakhalenso chokhumudwitsa. Mwinanso mungafune kuyang'ana mutu wanu, womwe nthawi zambiri umayambitsa latency.
- Ngati pulogalamuyi ilipo potembenuza chizindikiro kapena kuchokera ku analog kapena digito, icho chokha chingapangitse latency.
- Kukhumudwa kumachitika pokhapokha ngati deta yamvetsera ikusamutsidwa komanso pamene pali kusiyana pakati pa nthawi ya zochitikazo zonse, ndipo zingayambitsenso kuvomereza.
