Abstract
An available bandwidth measurement system and method.The available bandwidth of a network path is determined by determining round-trip times of packets utilizing varying bandwidth to a receiving node. An increase in packet round-trip time indicates congestion of a link in the path. In some embodiments, the bandwidth range measured is expanded or decreased to locate a congestion point or to provide greater precision in determining available bandwidth.
