Topical issues of comparing time scales in packet telecommunication networks

High quality of the provided communication services can be reached by package networks by the organization of network synchronization of the time scales (TS). The report summarizes the experience of comparing the TS of the leading watches of the corporate telecommunication network with the state time scale - UTC (SU). The methods of realization of checking of a time scale and methods of distribution of time signals on a network are considered. In the report are presented the results of approbation on real networks of the technique of measuring the difference (divergence) of TS on the networks elements proposed by research and development company “KOMETEH”. Results of pilot studies are given and practical recommendations about distribution of time scale signals over a network with the required accuracy with using the equipment of domestic production are made.
