Оценивание состояний очередей заявок на узлах инфокоммуникационных сетей

Abstract

Relevance of the solution of a problem of estimation of states of requests queues on the infocommunication network nodes, allowing to carry out prognostication of the states of noobserved nodes of networks is proved. The method of estimation of states of requests queues on noobserved network nodes, considering network structure and distance of estimated nodes from wellknown state nodes. The dependences, reflecting a degree of influence of nodes states on the estimation accuracy of states of requests queues in infocommunication network nodes on the base of simulation modeling of infocommunication network with decentralized control functioning process of in conditions of non-stationary traffic in AnyLogic programming environment are received. The dependences of estimation quality of requests queues using factor from distance of considered nodes are presented. The outcome regarding reasonability of proposed method of states of requests queues in infocommunication network nodes estimation problem in decision of synthesis problem of adaptive routing algorithm in decentralized control network with non-stationary traffic.

В статье обоснована актуальность решения задачи оценивания состояний очередей заявок на узлах инфокоммуникационных сетей, позволяющей осуществить прогнозирование состояний ненаблюдаемых узлов сетей. Представлен способ оценивания состояний очередей заявок на ненаблюдаемых узлах сети, учитывающий структуру сети и удаленности оцениваемых узлов от узлов с известным состоянием. На основе имитационного моделирования процесса функционирования инфотелекоммуникационной сети с децентрализованным управлением в условиях нестационарного трафика получены зависимости, отражающие степень влияния состояний узлов сети на точность оценивания состояния очереди узла сети. Приведены оценки зависимости качества оценивания коэффициента использования очереди узла сети от удаленности узлов, состояния которых учитываются. Обоснован вывод о целесообразности предложенного подхода к решению задачи оценивания состояний очередей на узлах инфотелекоммуникационной сети при решении задач синтеза алгоритмов адаптивной маршрутизации в сетях с децентрализованным управлением и нестационарным трафиком.
