Abstract: An approach to link utilization measurement was proposed: The source sends probe packets which have the time stamp options being set. The current router time is recorded in the packets. Since the packet processing delay, propagation delay and the impaction of the router clock skew greatly affect the probing results, the probing results are processed with the link utilization statistic (LUS) algorithm and the queuing delay of each probing packet is therefore obtained. When quantized and smoothed with the slide window, the queuing delay is finally transformed into link utilization. This approach is verified through simulation.

Key words: time stamp, link utilization, clock skew, slide window
