End-to-end packet losses of one or more traffic streams transmitted across a congested network may be reduced by modulating the bandwidths of the corresponding traffic streams applied to node(s) of the network from one or more control points along the network topology. This reduction in packet loss results in a reduction in fluctuations or variability of the controlled traffic streams, an increase in bandwidth utilization and a reduction in times to transmit files. The control points can be either upstream or downstream of one or more congestion points along the network. The modulation of the bandwidths are governed by a nonlinear differential equation that involves feedback of the throughput and buffer occupancy level. The control terms involve a relaxation time, coupling constant, control constant and nonlinear feedback constants.

A method of controlling packet loss within a congested network, comprising:
A communication network comprising a number of nodes interconnected with one another through one or more communication links, a first one of the nodes being configured to control packet loss within the network by modulating packet bandwidths over selected ones of the communication links according to a process that can be represented by a nonlinear differential equation that involves a product of throughput of the selected communication links and a buffer occupancy level of the first node.
