Adaptive clock synchronization schemes for real-time traffic in broadband packet networks

Abstract

The authors illustrate the phenomenon of packet jitter using a simple example and propose methods by which the destination clock frequency can be adjusted, so that it follows the source clock frequency asymptotically while minimizing the effects of packet jitter on the outgoing packet stream. They provide a comprehensive asymptotic analysis of the estimation and control algorithms and discuss their implementation. The authors provide a systematic design procedure for choosing the relevant parameters for implementation and discuss the sensitivity of the performance with respect to these parameters.<>
