The purpose of research is to solve the problem of channel bandwidth scheduling data network polygon measuring system for testing of aircraft. Transmission time measurement information of the frame is modeled by normalized second-order Erlang distribution with the addition of constant component of transmission time. Signal transmission frame time distribution is found with the help of the theory of analytic functions of a complex variable. With the use of numerical methods of the theory of GERT-network the value of aggregate bandwidth of data network channels is determined. The optimum solution is found using genetic algorithms with constraints on the average time frame of measurement systems to test control center, as well as restrictions on the amount of the reserve channel bandwidth. Visualization of traffic on the network description of measuring complex polygon is given.

Key words: test aircraft, measuring information, data network, virtual channel, traffic balancing, deductions theory, distribution of frame transmission time, bandwidth, genetic algorithms, traffic visualization.
