Abstract--The explosive growth of the Internet has induced a need for
developing tools to understand the composition and dynamics of the In-
ternet traffic. Measurements of the various characteristics of a network
provide insight into the state and performance of the network whether it is
behaving as expected and whether changes in the network have improved
or degraded its performance. Available Bandwidth on the links of a net-
work is an important metric which can predict the performance of the net-
work. In this paper, an estimation algorithm for the available bandwidth
on a link is presented. The algorithm estimates the available bandwidth
