A New Available Bandwidth Measurement Method Based on Self-Loading Periodic Streams

We present a new available bandwidth measurement method based on self-loading periodic streams (SLoPS) in this paper. SLoPS sends probe stream at specific rate and estimates the available bandwidth from the inference of self-induced congestion. Contrary to traditional SLoPS method, the new method infers the congestion from a parameter named interval difference, not end-to-end delays. In probing scheme, the new method exponentially adjust probe rate to demarcate a rough bandwidth range and constringe the rate to available bandwidth value with quick search in the rough range. Since it uses only interval times of packets, our method does not require high time-stamping accuracy nor synchronous at the sender and receiver. We test our method in controlled and reproducible environment using NS2, and the simulation experiments show our method is accurate, quick and non-intrusive.
