Abstract

"The Connection Admission Control (CAC) is part of ATM traffic control and consists of a framework that optimizes network usage while ensuring the desired QoS for the services. The CAC approach we propose for ATM networks is based on a effective bandwidth allocation strategy. This paper addresses the effective bandwidth computation based on a probabilistic model for cell level QoS and call level QoS. Many papers concerning this subject usually consider only cell QoS parameter. We propose a call-admission criteria derived from load-sharing and Kaufman approximation that allows to simplify the blocking probability analysis of a multirate link."
