Abstract: The CAC algorithm presented aims at reducing the complexity of the computation, raising its call processing capability in real time, andmeanwhile raising the utilization of the network resources. By dividing equallythe link capacity into a flight of stairs, through a recursive computation, wecan estimate the quality of service on the link and make the decision to acceptor reject the calls. The performance of the algorithm is analysed according to the circumstances of our applications. The algorithm uses only two traffic parameters easily declared and policed, the peak bit rate and the average bit rate. The CAC scheme is simple and can be realized in real time.
