Kodi ndili ndi Bandwidth Yokwanira Kwa VoIP?
Chinthu chimodzi chomwe chimapatsa PSTN mwayi wapamwamba kuposa VoIP ndi khalidwe la mawu, ndipo chimodzi mwa zifukwa zomwe zimakhudza khalidwe la voiz mu VoIP ndiwongolande. Kuti muwone mwachidule za kugwedezeka ndi mitundu yothandizira, werengani nkhaniyi . Pano, tikuyesera kulingalira, pazochitika zinazake, kaya chiwongolero chopezekapo ndicho chiwongolero chofunikira.
Funso limeneli ndi lofunika kwambiri kuti tipeze maitanidwe abwino, komanso ndi ofunika kwambiri kwa omwe amagwiritsa ntchito njira zamakono. Adzafuna kudziŵa kuchuluka kwa maulendo awo a DIP akudziwika.
Kawirikawiri, 90 kbps ndi okwanira pa VoIP yabwino (kupatula, zowonjezera, zinthu zina ndizo zabwino). Koma izi zikhoza kukhala chinthu chosowa kwambiri m'madera omwe kugwiritsira ntchito mphamvu zamakono kuli okwera mtengo kwambiri, kapena m'magulu a mgwirizano komwe kulipikisana kwapadera kumayenera kugawidwa pakati pa ogwiritsa ntchito ambiri.
Ngati muli ogwiritsira ntchito, yesetsani kupewa maulumikila 56 kbps a VoIP. Ngakhale izo zigwira ntchito, zikhoza kukupatsani inu mwayi woipa wa VoIP. Kuthamanga bwino kwambiri ndi kugwirizana kwa DSL. Pamene ikupita kupitirira 90 kbps, ndiwe wabwino.
Kwa makampani omwe amagawidwa ndiwombowidth ndipo amayenera kukonza zipangizo zawo za VoIP molondola, olamulira amayenera kukhala owona ndi otsika kapena kukweza makonzedwe awo a khalidwe molingana ndi bandwidth weniweni omwe alipo pa wosuta. Zizindikiro zapadera ndi 90, 60 ndi 30 kbps, iliyonse imakhala ndi khalidwe losiyana la mawu. Chimene chisankha chidzangodalira kokha kugulitsidwa / khalidwe la malonda omwe kampani ikufuna kupanga.
Chomwe chimapangitsa kusintha kwapangidwe kake kumakhala kosinthika ndi ma codecs , omwe ali ndondomeko (magawo a pulogalamu) omwe alipo mu zipangizo za VoIP pofuna kupanikizira deta. Ma codecs a VoIP omwe amapereka khalidwe labwino amafuna zambiri zamtunduwu. Mwachitsanzo, G.711, imodzi mwa codecs yabwino kwambiri, ikufuna 87.2 kbps, pamene iLBC iyenera 27.7 okha; G.726-32 imafuna 55.2 kbps.
Kuti mudziwe kuchuluka kwa bandwidth omwe muli nawo komanso momwe zilili ndi VoIP yanu, mungagwiritse ntchito maulendo ambiri pa intaneti omwe akuwoneka mofulumira . Pali zida zomwe ziri zenizeni ndi zolondola, kwa zotsatira zina zamakono. Chitsanzo ndi VoIP bandwidth calculator.
Ndikofunika kufotokozera kuti kuchuluka kwa bandwidth kumafunika ndipo kuchuluka kwa deta yomwe imasamutsidwa pafoni kumadalira pa pulogalamu kapena ntchito yomwe imagwiritsidwa ntchito, yomwe imatembenuzidwa imadalira zinthu zowonjezera monga codecs zomwe zimagwiritsidwa ntchito. Mwachitsanzo, Skype amadya deta yambiri pamene imapereka mawu omveka bwino ndi mavidiyo. WhatsApp imatenga zocheperapo, komabe kwambiri poyerekeza ndi mapulogalamu opepuka monga Line. Nthaŵi zina, pofuna kuyankhulana bwino, anthu amasankha kuchotsa kanema kuti azikhala ndi khalidwe labwino, chifukwa cha kuchepa kwa chiwongolero.
