A low overhead, self adaptive method for end-to-end available bandwidth estimation was proposed. Firstly, on low utilization path, the mathematic equation between the probability that input probe gap increases caused by CT packets and the distribution of output probe gap was set up, and then CT load was derived from the equation. Secondly, a metric called gap symmetry (GS) was proposed to weigh the busyness degree of a network path, and the self adaptive available bandwidth estimation method based on GS was presented. NS-2 simulations show that compared with previous methods, our method shows its advantages in terms of measurement time, accuracy, and overhead.
