Abstract
A method and apparatus for flow control for sources in packet switched networks is implemented. A data rate for the source is determined based on a critically damped second-order system in response to a congestion signal sent by a destination node or other network device. The data rate is damped toward a share value that is also based on a critically damped second-order system. The resulting flow control reduces packet loss and improves network utilization.
