I-Latency Voice Causes Echos kunye neeNandi eziHlangayo
I-Latency yinto yokulibaziseka okanye ilahleke into ethile. Unako ukufumana i- latency kumanethiwekhi ekhompyutha kodwa nakwixesha lokunxibelelana ngezwi. Eyona nto imbi kakhulu kwaye ingxaki enkulu kwiifowuni zezwi.
I-Latency yithuba phakathi kwexesha iipakethi yezwi idluliselwa kwaye ifikelele ekufikeleleni kwayo, ekhokelela ekulibazisekeni kwaye echotshiswe kubangelwa uxhumano lwenethiwekhi . I-Latency iyinkxalabo enkulu kwiinkcukacha zeVoIP xa kuziwa ekufowuneni umgangatho.
Kukho iindlela ezimbini zokulandelwa kwexesha elilinganayo: ulandelelwano olulodwa kunye nohambo olujikelezayo. Olunye ulwalathiso lwexesha eliqhelekileyo lixesha elithatyathwe ukuba ipakethe lihambe enye indlela ukusuka kumthombo ukuya kwindawo eya kuyo. I-latency ye-Round-trip yixesha elithatha ukuba iipakethi lihambe kwaye livela kwindawo eya kuyo, libuyele kumthombo. Enyanisweni, akuyiyo ipakethi efanayo ehambayo, kodwa ukuvuma.
I-Latency ibalwa ngamanitha-millisecond (ms), eyiyo eyiyure eyimizuzwana. I-latency ye-20 ms iqhelekileyo kwiifowuni ze-IP kunye ne-150 ms ingabonakali kwaye iyamkeleka. Nangona kunjalo, nawuphi na ophezulu kunalo kwaye umgangatho uqala ukunciphisa; 300 ms okanye ngaphezulu kwaye ayivumelekanga ngokupheleleyo.
Qaphela: I-latency yefowuni ngamanye amaxesha ibizwa ukulibaziseka komlomo ukuya kwindlebe , kunye ne-intanethi ye-intanethi ye-audio latency ihamba kunye nekota yeqondo okanye i- QoE.
Imiphumo yeLatency kwiifowuni zezwi
Ezi zimbalwa zempembelelo ezimbi ze-latency kumgangatho wocingo:
- Ukucima umnxibelelwano wefoni yakho
- Ukungaqiniseki kunokubangela ukuvakala komsindo, kunye nesithethi esinye saphazamisa esinye
- Iimeko ezibangela
- Ukuvumelanisa ukuhamba phakathi kwezwi kunye nezinye iintlobo zeenkcukacha, ingakumbi ngexesha leenkomfa zevidiyo
Indlela yokuLahla ukuhamba kwexesha
Lo ngumsebenzi onzima kwaye ufuna ukuba uqwalasele izinto ezininzi, ezininzi zazo ezingaphezu kolawulo lwakho. Ngokomzekelo, awukhethi ukuba yeyiphi i-codec umniki-wesevisi wakho esebenzisa.
Nazi izinto ezenza ukuba iVoIP latency:
- Awunayo ibhanwidth eyaneleyo. Xa uxhumano lwe-intanethi lucotha, iipakethe zedata zithatha ixesha elide ukuqhubela phambili kwaye le nto yenza ukuba unxibelelwano luhlupheke. Ngokuqhelekileyo, iipakethi zifika ngendlela engafanelekanga, eyenza ukuba i-reassembly ingenakwenzeka ngaphandle kokuba i-oda libuyiselwe. Le ngenye yezinto ezingalunganga zokupakisha ipakethe, esebenzisa iVoIP.
- I-firewall yakho inokuthi ithintele ithrafikhi. Iimpawu zokujonga zihlala ziyi-bottleneck, ke qiniseka ukuba uvumela imvume yeefayile ze-VoIP kwisofthiwe ye-firewall .
- Iicodec ezingalunganga zisetyenziswa. IiCodec ziinkqubo ezisetyenziselwa ukufakela iimpawu zamagama kwidijithali yedluliselo kwi-intanethi, kwaye umniki wakho unokusebenzisa okungahambiyo, okungekho nto ongayenzayo. Nangona kunjalo, ukuba usebenzisa ii-app ze-VoIP ezikuvumela ukuba ulungele i-codec, zama ukuguqula.
- Usebenzisa i- hardware endala. I-hardware endala kunye nesofthiwe entsha okanye amanethiwekhi amaninzi angase asebenze kakuhle kwaye azilibazise kwaye i-latency ivame ukuphumela. Kufuneka uzame ukusebenzisa i-adapter yomnxeba eyahlukeneyo okanye ifowuni eyahlukileyo (ukuba usebenzisa i-IP yefoni okanye nayiphi enye i-hardware ye-VoIP). I-hub yakho inokuthi ibe yinto enobungozi. Unokufuna ukujonga i-headset yakho, edla ngokubangela ukuba i-latency ivele.
- Ukuba inkqubo inendawo iguqula isalathisi kuye okanye kwi-analog okanye yedijithali, loo nto yodwa inokufaka isandla kwi-latency.
- Ukuxubha kwenzeka ngokubini xa idatha yomsindo idluliselwa kwaye xa kukho umehluko phakathi kwexesha lezibini iziganeko, kwaye kungabangela ukukhanya komsindo.
