Abstract
The flow-based mathematical model of queue management on routers of telecommunication networks on the basis of optimal aggregation of flows and bandwidth allocation in queues has been further developed. The novelty of the model is that when flows are queued, they are aggregated based on the comparison of the classes of flows and queues in the course of analyzing the set of classification characteristics. Moreover, the result of calculating the percentage of unused queues in the course of optimal aggregation of flows provided assuming the hypothesis of a uniform or normal distribution of flow service classes within the framework of the model under consideration is presented. Applying the uniform distribution law, it was possible to reduce the number of unused queues by 20%, and by 30% for the normal distribution. Research results confirmed the efficiency of the proposed model.
