I-Latency Voice ibangela ama-Echos namazwi aqoshiwe
I-Latency ukulibaziseka noma ukugoba okuthile. Ungakwazi ukuhamba kwesikhathi kumakhompiyutha wekhompuyutha kodwa futhi ngesikhathi sokuxhumana ngezwi. Empeleni iyaziwa kakhulu futhi iyinkinga enkulu ekushaya izingcingo zezwi.
I-Latency yisikhathi phakathi komzuzu iphakethe lezwi lithengiswa futhi lapho lifika lapho lifika khona, okuholele ekubambezelekeni futhi kuboniswe ngenxa yezixhumanisi zenethiwekhi ezisheshayo . I-latency iyinkinga enkulu ekukhulumeni kwe-VoIP uma kuziwa ekutheni izinga lokubiza.
Kunezindlela ezimbili ze-latency ezilinganiswayo: ukuqondiswa okulodwa nohambo olujikelezayo. Enye i-latency orientation yisikhathi esithathiwe sokuba iphakethe lihambe ngendlela eyodwa ukusuka emthonjeni kuya endaweni eya kuyo. Ukuhamba kwesikhathi sokujikeleza yisikhathi esithatha ukuba iphakethe lihambe futhi lisuka lapho liya khona, libuyele kumthombo. Eqinisweni, akuyona iphakethe elifanayo elibuyela emuva, kodwa ukuvuma.
I-latency ilinganiswa ngamamillisecond (ms), okuyizinkulungwane zamasonto. I-latency ye-20 ms iyinto evamile ukushaya izingcingo ze-IP namamitha angu-150 akucaci futhi kuyamukeleka. Noma kunjalo, noma yikuphi okuphakeme kunalokho nekhwalithi iqala ukunciphisa; 300 ms noma ngaphezulu futhi ayamukeleki ngokuphelele.
Qaphela: I- latency yocingo ngezinye izikhathi ibizwa ukulibaziseka komlomo kuya kwezindlebe , futhi i-latency audio latency ehambisana ne-intanethi nayo ihamba ngekhwalithi ye- term ye-experience noma i- QoE.
Imiphumela ye-Latency kuma Izingcingo zezwi
Lezi zingemiphumela embalwa nje emibi ye-latency kumgangatho wekholi:
- Ihlisa phansi izingxoxo zefoni yakho
- Ukungaqiniseki kungaholela emisindo ekhishwayo, isikhulumi esisodwa siphazamisa esinye
- Izimbangela zizwakala
- Ukuvumelanisa kwe-disturbs phakathi kwezwi nezinye izinhlobo zedatha, ikakhulukazi ngesikhathi sokuxhumana kwevidiyo
Ungasusa kanjani i-Latency
Lena umsebenzi onzima futhi udinga ukuba ucabangele izici ezimbalwa, eziningi zazo ezingaphezu kokulawula kwakho. Isibonelo, awukhethi ukuthi iyiphi i-codec umhlinzeki wakho wesevisi esebenzisa.
Nazi izici ezivame ukubangela ukulandelwa kwe-VoIP:
- Awunayo i- bandwidth eyanele. Uma uxhumano lwe-intanethi luhamba kancane, amaphakethe wedatha athatha isikhathi esiningi ukugeleza kuze kube manje futhi lokhu kubangela ukuthi ukuxhumana kuhlupheke. Ngokuvamile, amaphakethe afika ngendlela engalungile, okwenza ukuvuselela kungenzeki ngaphandle kokuthi i-oda libuyiselwe. Lokhu kungenye yezinkinga zokushintsha kwepakethe, okuyinto i-VoIP isebenzisa.
- I-firewall yakho ingase ivimbele ithrafikhi. Izikhathi zokuhlola zihlala ziwu-bottleneck, ngakho qiniseka ukuthi uvumela imvume yezinhlelo zakho ze-VoIP ngaphakathi kwesofthiwe ye-firewall .
- I-codec engalungile isetshenziswa. Ama-Codec yizinhlelo ezisetshenziselwa ukufaka amarekhodi wezwi kwimininingwane yedijithali yokudlulisela phezu kwenethiwekhi, futhi umhlinzeki wakho angase asebenzise okungalungile, okungekho lutho ongakwenza. Kodwa-ke, uma usebenzisa izinhlelo zokusebenza ze-VoIP ezikuvumela ukuba uzihlanganise nge-codecs, zama ukuzishintsha.
- Usebenzisa i- hardware endala. I-hardware yakudala ene-software entsha noma amanethiwekhi amasha angeke asebenze kahle futhi aphuze futhi ukuvama ngokuvamile kungumphumela. Kufanele uzame ukusebenzisa i-adapter yefoni ehlukile noma ifoni ehlukile (uma usebenzisa i-IP yocingo noma enye i-hardware eqondene ne-VoIP). Ihabhu lakho lingase libuye libe yikhomba. Ungase ufune ngisho nokuhlola i-headset yakho, okuvame ukubangela ukuhamba kwesikhathi.
- Uma uhlelo olusha luguqula isignali noma kusuka ku-analog noma idijithali, lokho kuphela kungase kube nomthelela ekugcineni.
- Ukuqhuma kwenzeka kokubili uma idatha yomsindo idluliselwa futhi uma kukhona umehluko emkhatsini wezo zenzakalo zombili, futhi kungabangela ukukhanya komsindo kanye.
