Abstract.

The paper deals with the methodology of an assessment of technical efficiency of network infrastructure. Much attention is given to research of methods of visualization of performance metrics on the basis of comparing of the evaluated sample with a set of alternative decisions in the conditions of stochastic nature of behavior of an external environment. The method of visualization of time response characteristics of access to resources of the Internet offered in operation is developed especially for demonstration of advantages which can be received when using the concept of "cognitive Internet". Unlike numerical efficiency characteristics the offered method of visualization allows to envelop "one look" a status of all channels of access in comparison with the optimum channel on the given time slot of integration. At the same time the method doesn't exclude possibility of sharing of the coordinated numerical efficiency characteristics. On the other hand it is important to mark that scope of a method isn't restricted to the specified applications.Methods of multivariate statistic analysis (methods of discriminant function analysis and principal component analysis) are the basis for algorithm elaboration of visualization of time response characteristics of access to resources of the Internet. The main result of the conducted research is algorithm elaboration and the software of visualization of metrics of productivity of infrastructure decisions in the field of ensuring access to Internet resources. Novelty of this research is defined not only novelty of data domain (technology of the cognitive Internet), but also the form of representation of results (a projection of the hodograph of time response characteristics of access to the most informative plane).

Keywords: technical efficiency, performance metric, dimensionality reduction, principal component analysis, cluster analysis, visualization, characteristic vector, characteristic value, cognitive internet, discriminant function analysis
