The basic issue in connection acceptance control (CAC) design is the determination as to whether a new connection request can be accepted while guaranteeing that its quality of service (QoS) specifications can be met and not affecting the on-going connections. In the talk I will present an approach to this problem via the use of a multi-rate loss framework given that there are VBR and CBR requests. In particular we show that when the size of the VP in terms of capacity is large this problem can be addressed fairly satisfactorily. The key ideas are based on measure change techniques, local limit theorems and most likely configurations which allows us to exploit source statistics to define effective rates of connections. With this setting we show that we can define a set of decoupled effective rates which allows us to decide whether the connection requests can meet delay, cell loss and connection burst constraints. In particular we show that the multiplexing gains achieved by this approach are higher or match the results on this problem which have been reported in the literature.
