Notice of RetractionNetwork jitter and impairment handling mechanism in Voice-over-IP systems

In voice-over-IP systems, IP packets are transmit according to best of effort principle, so here usually existing jitter or packets loss, packet error. Jitter concept, common network impairment system model and common jitter handle model are introduced in paper. Two kinds of JB (jitter buffer) options are both used in PEM board and they are respectively flexible to comfort fixed and time-variant network by analyzing jitter handling characteristics.
