Abstract: The article deals with processes of design and creation of the secure wide area network (SWAN). Object of research is the subsystem of distribution of exact time of SWAN. Existence of the specified subsystem is the basic requirement from the point of view of safety of functioning of a network. Means of registration of events in SWAN, systems of the analysis of protocols of events, intruder detection systems is only a small list of subsystems of SWAN which can't exist without service of exact time. On the other hand, the specified service can be considered as the SWAN client service. In this quality the service of exact time in computer networks from year to year becomes more and more demanded. At the same time it is not a secret that as the sources of exact time in modern SWAN the production of the western countries are used. Thus, in view of categories hi-tech of the specified products, the corresponding production isn't taken out to the countries of Asia. Respectively today in this sphere there are certain difficulties at selection and the order of the equipment.  Considering above told, author in detail considers such aspects of import substitution regarding creation of services of exact time of SWAN, as existence of available basic sources of exact time in the Russian Federation, presence of domestic producer of the equipment in the relevant market, economic aspects of consequences from realization of possible import substitution. The special attention is paid to the standard configurations of sources of exact time in SWAN which are based on the equipment of a domestic production. The article is based on set of results of the researches of the domestic market of radio electronics conducted by author. As sources of information the Internet publications and phone calls to the sales departments of a number of producers were used. When forming the purposes of market researches the standards in the field of protocols of distribution of exact time over the Internet-protocol and also some researches of the author were used. The main conclusion of the conducted research is ascertaining of possibility of use as sources of exact time in SWAN of the complexes constructed on the equipment of domestic producers. A special contribution of the author to the research of a subject is development of recommendations for domestic producers regarding correction of their market behavior. Novelty of the research is in the use of the concept of total cost of ownership when comparing various scenarios of creation of subsystems of distribution of exact time in the computer networks which are based on the Internet-protocol.


Keywords: accurate time server, RBU, clock synchronization, RTZ, GLONASS, GPS, NMEA, network, NTP, total cost of ownership
