The performance of the CAC scheme based on the periodic measurement of traffic (PMT) using the statistical bandwidth in ATM networks is studied. The proposed PMT CAC scheme implements the dynamic admission control which can be applied to the distinct delay-sensitive variable-bit-rate sources. Since the estimated bandwidth and buffer resources can be allocated adaptively by the aggregate traffic measurement, the proposed PMT CAC scheme has great flexibility in the bandwidth allocation according to the network status. Simulation results show that the higher the burst of cell arrivals become, the greater the multiplexing gain that can be obtained. The proposed scheme is expected to be less overly conservative than conventional methods, so that the network resource utilisation can be greatly improved
