Abstract

This paper proposes an ATM traffic management method that combines a deterministic source traffic descriptor, a deterministic usage parameter control (UPC) algorithm, and a conservative statistical bandwidth allocation method. The source traffic descriptor is based on sliding time interval‐type descriptors for both the peak‐rate and the average‐rate. A UPC method which combines a sliding‐window‐type circuit and a two‐phase credit‐window‐type circuit for widely‐ranging traffic parameter values is proposed. The method is precise and accurate, and requires only a small amount of hardware. The bandwidth allocation method uses the worst pattern that can be transmitted through the proposed UPC circuit. The proposed traffic management method not only guarantees the QOS of all connections, but also allows for large statistical multiplexing gain. The proposed method, therefore, makes it possible to create a more effective BISDN, one that can offer cost‐effective broadband VBR services.
