A multidimensional approach to congestion control in integrated broadband networks is described, and a framework for a congestion control strategy that is applicable to virtual-circuit-based services as well as connectionless services is developed. The proposed congestion control strategy is based on a set of temporal controls, classification of services is based on their traffic characteristics and quality of service (QOS) requirements, and partitioning of the control space is based on the reaction time of the controls and the network time constants. The congestion control framework is simple, scales as the delay-bandwidth product increases, and is well suited for the asynchronous transfer mode that is being promoted as the underlying transport for B-ISDN.
