Abstract: This paper describes queue monitoring, a policy for managing the effect of delay jitter on audio and video in computer-based conferences. By observing delay jitter over time, this policy dynamically adjusts display latency in order to support low-latency conferences with an acceptable gap rate. Queue monitoring is evaluated by comparing it with two other policies in an empirical study of a computer-based conferencing system. Our results show that queue monitoring performs well under a variety of observed network loads.
