Abstract

A common method for regulating the input flow in today's telecommunication networks is the implementation of reactive traffic control mechanisms. By limiting the user's access according to the current network load situation, the throughput is optimized while congestion is avoided. In ATM networks, for example, a rate-based feedback control is applied to dynamically adjust the transmission rates of connections belonging to the ABR service category. This paper presents a discrete-time analysis of a queueing model with non-deterministic arrivals and delayed feedback. The binary feedback information is used to regulate the input flowbychanging the inter-arrival distribution accordingly. Applying this model, the performance of the ABR flow control can be studied with respect to the variabilityofthecell generation process.
