Problem: Jitter Buffer

A jitter buffer temporarily stores arriving packets in order to minimize delay variations. If packets arrive too late then they are discarded. A jitter buffer may be mis-configured and be either too large or too small.


If a jitter buffer is too small then an excessive number of packets may be discarded, which can lead to call quality degradation. If a jitter buffer is too large then the additional delay can lead to conversational difficulty.


A typical jitter buffer configuration is 30mS to 50mS in size. In the case of an adaptive jitter buffer then the maximum size may be set to 100-200mS. Note that if the jitter buffer size exceeds 100mS then the additional delay introduced can lead to conversational difficulty.
