De-Jitter Buffer Role in Improving VOIP Connection Quality – Examples from Practice

Keywords:
VoIP connection quality, E-model, equiquality lines „delay-packet loss“, de-jitter buffer.

Abstract:
This paper presents the way the optimum de-jitter buffer delay is determined to achieve maximum VoIP connection quality. This delay estimation is based on presentation of 1-CDF (1- cumulative distribution function) characteristics of packet delay distribution in the field of equiquality lines „delay-packet loss“ for applied coder (compressor). The results are based on a real measurement of end-to-end delay for different links in Internet and on coder (compressor) send side delay. It is proved that five-sixths connections have high or medium connection quality and that the corresponding de-jitter buffer delay is relatively small, while in about 5% of connections satisfactory connection quality cannot be achieved.
