A power-spectrum based connection admission control for ATM networks

The power spectrum of the input process explicitly contains the correlation behavior of input traffic and has a great impact on the queueing behavior of an ATM network. In this paper, we propose a power-spectrum based connection admission control scheme for ATM networks. The DC component, the average power, and the half-power bandwidth are the key factors of the input power spectrum. Here, we use a method to approximate the QoS by the result obtained from the equivalent average power. Finally, we construct an admission control table which contains the performance measure for different loads and the equivalent average power. Whether a new call can be accepted or not is determined by table lookup. Simulation results show that our proposed power-spectrum based connection admission control is an efficient control method for ATM networks
