The decisions of connection admission in ATM networks should be made in real time through the use of a fast algorithm. Since it is difficult to construct an accurate model for the multiplexed traffic, approximation of the multiplexed load is necessary. We focus on a dynamic CAC (connection admission control) algorithm as a different approach, in which admission control decisions are made based on network measurements. The algorithm observes the traffic through a moving window and the window size is recomputed from the measured cell loss. This approach also makes it possible to reallocate network resources (bandwidth and buffers) for multiple traffic classes. The performance of the proposed method is analyzed by means of simulated tests
