Bulletin of TUIT: Management and Communication Technologies


The article deals with the problems of determining the main quality indicators of a telecommunications network with different types of communication channels and the time-varying structure of their functioning to ensure the specified reliability and time of delivery of protected messages to information consumers. The main method of solving this problem is using analytical and simulation methods on personal computers. Comparison of the obtained simulation results with the results of analytical models are also given.

The developed algorithms for simulation of the process of transmitting messages in various transmission modes allow obtaining distribution of time for message delivery in the system, waiting times for messages in the communication center and many other benefits.
