Buffer allocation in general single-server queueing networks

-- The optimal buffer allocation in queueing network systems is a difficult stochastic, non-linear, integer mathematical programming problem. Moreover, the objective function, the constraints or both are usually not available in closed-form, making the problem even harder. A good approximation for the performance measures is thus essential for a successful buffer allocation algorithm. A recently published two-moment approximation formula for predicting the optimal buffer allocation in general service time single queues is examined in details, based on which a new algorithm is proposed for buffer allocation in singleserve general service time queueing networks. Computational results are shown to evaluate the efficacy of the approach in generating optimal buffer allocation patterns. Keywords -- Buffer allocation; queues; networks.
