Abstract: Measuring the link bandwidth is an open issue. Many scholars in the world are committing themselves to this work. Unfortunately, it is difficult to measure the link bandwidth accurately and fast. Up to now, we are still not able to get a method to measure the link bandwidth quite accurately and fast. In this paper, we first analyze the performance and the disadvantages of the existing one packet probe technique. To remedy its default, we put forward a new measurement technique called multi-packet probe technique. Finally we make a simulation to validate the new measurement technique. We find that, compared with the one packet probe technique, the multi-packet probe technique has higher accuracy, higher measuring speed and lower resource cost.

Key words: link bandwidth, bandwidth measurement, RTT latency
