The paper focuses on fast reservation mechanisms used to control network links carrying random bursty traffic in ATM-based broadband networks and proposes a method for supporting wide area connections. Very high speed networks supporting integrated services are evolving towards new bandwidth management approaches. On the one hand, advance reservation for the duration of the call requires traffic descriptors which are difficult to determine for the user. On the other hand, wide area links have large latencies so that dynamic controls are difficult to apply. The traditional rate control, enhanced through a form of transmission scheduling can provide a reasonable trade-off between delay and losses. The paper analyses the options available for bandwidth management in ATM-based networks carrying predominantly data traffic, and develops a rationale for supporting fast reservation protocols for high bandwidth links using dynamic switching based on a measure of the link latency. A novel burst quantization technique is used for burst recognition. The trade-off associated with these approaches is characterized using trace driven simulation.
