摘要

The article considers issues associated with the provision of metrological support for packet networks. The main traceability issues in the transfer of measurement units of packet network parameters to measuring instruments are described. The authors present the results of analyzing a fleet of measuring instruments traceable to GET 200-2023 State Primary Standard of the transmitted (received) information (data) unit and the units of packet network parameters. The fundamental differences between methods for measuring packet network parameters by means of GET 200-2023 or measuring instruments and working standards are considered. Network parameters determining network integrity and stability include throughput, packet delay, packet delay variation, and packet loss ratio. It is established that in the parameter measurements of operational networks, the fractal and avalanche-type behavior of packet networks complicates the application of statistical mathematics and classical error theory, and the measurement turns into an iterative research process. The method of applying rigorous logic (implemented in GET 200-2023) to obtain a sync pulse tied to a logical event is shown to avoid the time uncertainty problem of the logical event, which is typical of programmable measuring instruments. The authors note a number of issues related to the provision of metrological support for packet networks that are not yet covered by legislative acts and lack an adequate technical solution. Government agencies in the field of legal metrology and all interested parties are invited to pay special attention to them.
