Estimation of available bandwidth plays a very significant role in route selection, load balancing and network security. This paper presents a novel technique for the available bandwidth measurement, which sends tri-packets probes to measure the utilization of the link. In contrast to the previous methods, the middle one packet in a tri-packets-probe is prioritized to measure both the output time gap and waiting time of the probe and improve the accuracy of the utilization measurement. The experiment results validate the new method and show that it is also sensitive to the variance of traffic
