Integral Quality Indicators of Modern Communication Network Functioning

Abstract

Currently, existing methods for evaluating the network performance of packet-switched networks are based on monitoring the excess of the values of network performance indicators of predetermined threshold values. At the same time, maximum, minimum and average values of indicators are widely used. In such operations, it is not taken into account that if the values of the indicators are in the range of permissible values, then the quality of the network connection is considered acceptable. It is most advisable to take into account the magnitude of the deviation of the indicator values from the areas of permissible values and the duration of such deviations. In this case, the deviation value will characterize the amount of network performance degradation, and the duration of the deviation will characterize the duration of the performance degradation. The network performance assessment thus formed will closely characterize the perception of the quality of the communication service by the user of the communication service. This article focuses on the development of such network performance metrics.
