Abstract: The paper presents a scheme for admission control at the call set-up in an ATM node, aimed at minimising the probability of blocking a call and at balancing this probability between traffic classes. The traffic is considered to be divided into traffic classes, characterised by statistical parameters like peak and average bandwidth and by quality of service (QoS) requirements that allow to define a feasibility region: where requirements are guaranteed A model to describe the 'call admission' is proposed: two different cost functions, based on the blocking probability, are defined and minimised, taking into account the 'feasibility region' constraint: the first function is intended to obtain the minimum overall blocking probability, whereas the second is aimed to balance the blocking probability among classes. The maximum number of acceptable calls yielded by each cost function is obtained for each class, by minimising it under stationary traffic conditions. The efficiency of the proposed strategy is tested by simulations and verified by comparing it with other admission schemes.
