Adaptive resource scheduling strategies and performance analysis of broadband networks

Abstract

Broadband networks are fast becoming integrated into the information infrastructure. The need to transport multimedia calls requiring not only high bandwidth but also minimal loss and delay is rapidly increasing. The increased ratio of propagation delay to bit duration creates new problems in dynamic control. This paper focuses on developing adaptive control strategies and dynamic resource scheduling algorithms which would efficiently allocate (B-ISDN/ATM) network resources (e.g., bandwidth and buffers), while maintaining the best possible quality of service. Multimedia calls are classified based on crossover behavior. Simulation models used to study the system performance are presented. Performance metrics of interest include network throughput, call blocking rate, and crossover blocking probabilities.
