Accurate prediction of VoIP traffic mean bit rate
Rafael Estepa, Antonio Estepa, Juan M. Vozmediano · Electronics Letters · 2005
An easy closed form for prediction of the mean bit-rate of one conversation generated by SID-capable speech codecs as a function of the codec and the number of frames per packet used is presented. The predicted mean bit-rate is compared to measured data and to the traditional ON–OFF model prediction, demonstrating the accuracy of the model. Results can also be applied to the output link capacity dimensioning when several homogeneous voice sources are multiplexed.
