A Multiplexing Scheme using a Prediction Based Scheduling Strategy for Self-Similar Traffic

: The flexibility given by ATM networks permits to reach high network resources utilisation when the traffic is managed considering its actual statistical behaviour. A dynamic managing of network resources (i.e. bandwidth and buffer space) improves the utilisation when considering heterogeneous sources corresponding to multimedia services. In this scenario the paper presents a multiplexing scheme which permits to dynamically allocate the bandwidth using an ad hoc scheduling discipline and a push out management of the buffer. The capacity assigned to each source depends on its predicted offered traffic and this information is also used by the scheduling algorithm. The prediction is linear and the design of the prediction filter is based on the self-similar modelling of the ingoing traffic, considering the statistical nature of traffic observed during measurements sessions. The performance of the proposed strategy in terms of multiplexing gain for reasonable values of cell loss ratio and...
