Virtual Path Resource Allocation Schemes in ATM Networks (Asynchronous Transfer Mode) (Report‪)‬

INTRODUCTION Today's networks are under ever-increasing competitive pressure to deliver more services to users while doing so at lower cost. Deregulation is occurring globally, resulting in a highly competitive industry with lowered entry barriers for new competitors as well as potential new markets for incumbents. At the same time, trends show a rapidly accelerating demand for bandwidth driven by advanced video and data services [3]. Currently, services are provided using multiple networks, often overlaying services on technologies not designed for today's range of applications. Asynchronous transfer mode (ATM) [5], by contrast, is a technology designed first and fore- most for flexibility to enable the carriage of multiple, and previously segregated, services over a single common backbone infrastructure. As multiple services share the same infra- structure, greater statistical gains can be achieved with improved utilization of backbone links.
