Abstract: This paper proposes an adaptive judgment algorithm of available bandwidth based on theory analysis and experiments. It uses adaptive periodic probe stream to judge delay trend and get probe result feedback adaptively by sending periodic train. It can measure available bandwidth accurately and fast. Simulation result shows that the algorithm is feasible and valid, and it is an end-to-end available bandwidth measurement method with little effect on network and low measurement price.

Key words: available bandwidth, delay trend, adaptive
