Data Transmission with Priority Service and Limited Capacity Storage in Unstationary Flow and High Load

Subject of research. The influence of priority service in a multichannel data transmission system with drives of limited capacity and high load with a non-stationary nature of the intensity of packets entering the system and service time in channels. Method. Calculation and analysis of the functional characteristics of a multichannel system is realized using simulation methods and mathematical statistics. Main results. A simulation model of a multichannel system with priority service is proposed to calculate the functional characteristics of a multichannel system with a high load. A number of experiments were carried out on the influence of priority maintenance on the efficiency and reliability of the system. Dependencies between stationary and non-stationary functional quantities have been identified. Practical significance. The presented research results can be used in the design of real multithreaded data transmission systems with a highly heterogeneous load.
