Summary: 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
challenging. In this poster we propose a novel technique to
predict packet loss in real-time audio streams based on the one-
way delay, inter-packet gap variation and delay trend, enabling
proactive error recovery and congestion control for real-time
audio over the Internet. Our preliminary simulation and
experimentation results with various sites on the Internet show
the high effectiveness and the accuracy of our loss predictor
technique.

I. INTRODUCTION
Quality of Internet audio communication is highly sensitive
to packet loss [3,8]. Majority of packet loss in the Internet
occurs as the result of congestion in the links. Packet
retransmission is not usually a viable option for real-time
audio, since it adds to the delay that might exceed allowable
mouth-to-ear delay bounds. Packet loss for audio is normally
