High speed networks are fast becoming an essential part of the information infrastructure. New problems in dynamic control of these networks arise due to the increased ratio of propagation delay to bit duration. Key network performance parameters (e.g., delay, cell loss, jitter) have to be observed while carrying various combinations of different types of traffic. This paper studies adaptive control strategies for dynamic resource allocation in broadband networks. Research goals include the development of adaptive control policies and dynamic resource scheduling algorithms which would efficiently and optimally allocate network resources (e.g., bandwidth and buffers), while maintaining the best possible quality of service for the different classes of calls. The use of reserved resources for each class of traffic in the dynamic allocation of network resources provides the required fairness and simplicity in implementing resource allocation control for high-speed networks while its adaptive control provides the network with an additional capability of adapting to the dynamics of the traffic load.
