Kev ntsuam xyuas cov qhab nias tau pom nyob rau hauv cov nqe lus ntawm tej yam tsis ua uas muab ib qho kev ntsuas ntawm ntau yam kev ntsuas. Tsis yog txhua qhov kev ntsuam xyuas ceev tau muab rau koj tib yam tsis tau nyob hauv kev soj ntsuam, tab sis txhua tus ntawm lawv muab lub download thiab upload speeds. Lwm yam tseem ceeb yog QoS, RTT thiab Ntau Zej Zog, ntawm lwm tus. Cia peb pom tias cov no yog dabtsi.
Tus Upload thiab Download Speeds
Ntsuas hauv kbps (kilobits ib pliag) lossis mbps (megabits ib pliag), cov kev ntseeg no piv rau tus nqi uas cov ntaub ntawv / suab tau downloaded rau koj lub PC lossis lwm yam VoIP hardware - zoo li thaum koj mloog thaum hu ua "Internet" - thiab muab los ntawm nws rau hauv Internet - zoo li thaum koj hais lus thaum hu. Rau lub suab nrov zoo hu, muaj kev ceev ceev ntawm 100 kbps thiab upload speed ntawm 80 kbps yog qhov zoo txaus. Nco ntsoov tias koj tuaj yeem muaj ib lub tswv yim ntawm koj upload thiab download speeds txhua lub sijhawm los ntawm kev txhim kho lub ntsuas 'network' ntawm koj lub computer.
QoS (Cov Haujlwm Uas Zoo)
QoS yog ib lub ntsiab lus loj hauv nws tus kheej, tiam sis hauv peb cov ntsiab lus ntawm kev sib tw ceev ceev, QoS sawv cev rau qhov kev nyeem ntawv phem tshaj plaws rau qhov zoo tshaj plaws. Nws yog qhov tseeb ib qho kev ntsuas ntawm theem ntawm kev sib txig nyob rau hauv download ceev. Hauv kev ntsuam xyuas ceev, nws yog sawv cev tam li ib feem pua. Qhov siab dua yog qhov zoo dua rau qhov zoo. Kom ua zoo VoIP, lub QoS yuav tsum yog 80% lossis ntau dua.Qhov zoo dua rau qhov zoo. Kom ua zoo VoIP, lub QoS yuav tsum yog 80% lossis tshaj rod saud.
RTT (Hloov mus ncig lub sijhawm)
Tus RTT yog lub sij hawm rau koj lub tshuab los yog lub tshuab kom xa ib pob ntawv me me thaum xeem thiab tau txais nws rov qab tom qab nws tau ua ib qho kev mus ncig ua ke hauv txoj kev taug kev hauv lub network. Nws yog ntsuas hauv milliseconds (ms). Tus me nws yog, qhov zoo dua yog kev twb kev txuas. Rau VoIP, nws yog OK kom muaj ib tug RTT tsawg dua 250 milliseconds.
Qhov no txhais tau hais tias lub pob ntawv ntawm cov ntaub ntawv tau noj tsawg tshaj li ib lub hlis twg ntawm ib pliag mus ncig los ntawm koj lub xov tooj mus rau kev xeem tus tswv tsev thiab rov qab. Hloov kev mus ncig ua si uas siv sij hawm ntau tshaj qhov uas yuav muaj koj hu xov tooj rau laggy thiab laggy thiab laggy thiab laggy thiab laggy thiab txawm tias yuav poob, vim cov ntaub ntawv tiag tiag nqa cov ntaub ntawv yuav qeeb, ua rau muaj kev nco zoo.
Max Pause
Qhov no yog qhov ntev tshaj plaws ntawm koj qhov kev ntsuam xyuas tau kaw tseg ntawm cov ntaub ntawv khaws tseg. Rau qhov zoo tshaj plaws bandwidth, qhov no yuav tsum yog ib tug xov tooj tsawg, lwm tus, nws yuav qhia tau hais tias yuav muaj teeb meem ntawm kev sib nkag hauv koj qhov kev txuas. Txhua qhov kev poob siab tshaj plaws hauv qab 100 yog qhov zoo rau VoIP.pause hauv qab 100 yog zoo rau VoIP.pause hauv qab 100 yog qhov zoo rau VoIP.pause hauv qab 100 yog qhov zoo rau VoIP.pause.pause hauv qab 100 yog qhov zoo rau VoIP.pause hauv qab 100 yog qhov zoo rau VoIP.
Cov txiaj ntsig no yuav tsum muab ib lub tswv yim zoo nkauj rau koj txog kev zoo li cas los yog qhov tsis zoo rau koj.
