Research of Influence Flow Characteristics to Network Routers Queues Utilization

Abstract

Research results of the influence flow characteristics to network routers queues utilization were presented. It is determined that the use of the steady state estimations when calculating the average queue length is possible only after the end of transient process. Otherwise, it is advisable to use a more accurate differential model. Results of analysis showed that the duration of transient process is influenced by such factors as flow rate, capacity of the router interface, service discipline, etc. Within this research it was shown that the use of non-linear differential model can improve the accuracy of calculation of the average queue length, depending on the state of interface and selected service discipline.
