A connection admission control (CAC) that guarantees a negotiated cell-loss ratio for all cell-streams passing through the usage parameter control (UPC) in ATM networks is proposed. In particular, the cases in which a jumping-window, sliding-window, or continuous-leaky-bucket scheme are used for peak-cell-rate policing are discussued, and the upper bound for cell-loss ratio of the cell-streams passing through each type of UPC is derived. The CACs based on the derived cell-loss-ratio upper bounds ensure the quality of service in all cases by combining the relevant UPCs. There are three possible combinations of CAC and UPC, depending on the UPC mechanism used. The impact of the choice of CAC and UPC combination on bandwidth utilization is discussed using several numerical examples.
