Abstract

We propose an adaptive measurement-based admission control algorithm that uses optimization procedure to choose an appropriate measurement window size dynamically. Previous designs on measurement-bared admission control mainly focused on strategies that consider the worst case traffic source model to guarantee QoS bounds for all connections. In this paper, we develop a simple mechanism in which both statistical multiplexing gain and QoS are considered An accurate formula for the cell loss probability which is combined with measurements, is presented for refined on/off traffic model. Furthermore, more accurate measurements of traffic would be given to admission controller through optimized window size. The proposed adaptive control is an appealing alternative: not only does it offer adaptivity to changing traffic conditions, but supports a guarantee that loss QoS bound is not violated due to the admission of new calls into ATM network. Simulations were performed to test the performance of the proposed algorithm.
