Abstract
A method and apparatus for controlling the data transfer rates of data sources in an asynchronous transfer mode-based network utilizing intelligent marking to identify those data sources with a data transfer rate exceeding a marking threshold and to direct those thus-identified data sources to reduce their data transfer rates, and to identify those data sources with a data transfer rate lower than a marking threshold and to direct those thus-identified data sources to increase their data transfer rates when the maximum data transfer rate at a communications switch exceeds a first threshold When the maximum data transfer rate at the communications switch exceeds a second thresholds directing all data sources to reduce their data transfer rates. The first and the second thresholds are based on a congestion indicator of available bit rate traffic stored in a buffer in the communications switch. The marking threshold equals a first function of at least a communications switch maximum data transfer rate multiplied by a second function of at least a first congestion indicator.
