Abstract-- The effect of packet loss on the quality of real-
time audio is significant. Nevertheless, Internet measurement
experiments continue to show a considerable variation of packet
loss, which makes audio error recovery and concealment chal-
lenging. We propose a novel framework to predict packet loss and
congestion, based on measurements of end-to-end delay variation
and trend, enabling proactive error recovery and congestion
avoidance. Our preliminary simulation and experimentation
results with various sites on the Internet show the effectiveness
and the accuracy of the Loss Predictor technique.
I. INTRODUCTION
Majority of the packet loss in the Internet occurs as the
result of congestion in the links. Many applications, such as
multimedia, are sensitive to packet loss, where packet retrans-
mission is not a viable option. It will be highly beneficial if
we can predict packet loss with a degree of certainty from
