TENSOR ANALYSIS METHODS FOR ESTIMATION OF AVERAGE DELAY OF INFOCOMMUNICATION NETWORKS

Infocommunication networks are telecommunication networks that intended for a transmission of different types streams. In infocommunication various characteristics are used for a quality of service estimation. One of them is an average delay for which a maximum value is defined by international standards. In this work we present results of the tensor analysis application to the estimating the average delay of infocommunication networks for determine the level of quality of service. Base definitions of the tensor analysis of the infocommunication networks modelling are suggest nodal and mesh methods for the implementation of the tensor approach to the estimation of probabilistic-temporal characteristics of the investigated networks. The nodal tensor model of infocommunication network uses intensity of traffic and intensity of service as an initial data that correspond to main initial parameters specified in the analysis of telecommunication networks. The mesh tensor model demonstrates good opportunities to estimate the average delay time for the routes of information transmission over the network, but the mesh method has some difficulties in the initial data selection. According to the obtained results it is possible to conclude that a nodal and mesh method of tensor analysis should be used together. The node method provides the ability to calculate the load of each network system based on the topology and influence of multiple sources, and the mesh method uses the results from the node model for the average delay determination for transmission routes in the infocommunication network.
