Introduction: An onboard computer network administration program receives, sends and processes a huge amount of data. The data processing should not be overloaded or slowed down, as the program is supposed to deal with possible critical situations on time. Therefore, the program should be subject to quantitative analysis in order to study its dynamic characteristics. Purpose: Analyzing the dynamic behavior of an onboard computer network administration program under various initial conditions and external influences. Results: A linear dynamic system was constructed, specifying a part of a particular onboard computer network administration program, representing a well-known plug-and-play manager. It is presented as a transition graph, showing relative parts of data coming from one state to another. Three situations were selected in which the program may be overloaded or slowed down. The system matrix were determined for the coefficients, inputs and outputs in each of these situation, along with the ways to avoid them. Computer simulation was carried out, using a script program created in MatLab mathematical package. The results of the simulation are charts showing how the program is loaded and controlled in time. The loading and control can change depending on the targeted load and the computational power of the linear dynamic system. The quantitative analysis presented in the article calculates the behavior of the plug-and-play manager in time, determined by its particular characteristics. Practical relevance: The presented formulas and developed program script allow us to simulate the functioning of an onboard computer network administration program under various load characteristics depending on the hardware and software implementation in a particular project, in order to avoid failures and errors during its operation.
