VP Bandwidth Management with Dynamic Connection Admission Control in ATM Networks

This paper discusses a VP bandwidth management with connection admission control (CAC) based on traffic measurements. i.e.. Dynamic CAC, in ATM networks. Dynamic CAC initially assigns a bandwidth equivalent to its peak cell rate for a new connection and then corrects it after traffic measurement. So Dynamic CAC has the advantage of statistical multiplexing gain, even when only the peak cell rate is notified to the network. To use Dynamic CAC effectively, however, it is important to appropriately set a parameter that specifies the weight of traffic characteristics in deciding admission. This parameter is called a smoothing parameter. This paper develops a method of designing the smoothing parameter.
