Abstract
One embodiment of the present invention includes a method for adaptively estimating available upstream bandwidth in a network. The method comprises monitoring data indicative of a number of lost packets at a near-end communication device. The data indicative of a number of lost packets can be periodically transmitted from a far-end communication device. The method also comprises increasing an amount of upstream bandwidth transmission until the monitored data exceeds a threshold. The method also comprises calculating an estimated available upstream bandwidth based on a portion of a maximum amount of the upstream bandwidth transmission.
