Abstract
In this article, the subject research is the efficiency of the processing systems information flows automotive service based on the architectural concept subsequent communication network using modern information technologies. As a criterion for the effectiveness of the functioning of the systems, the performance information processing systems was chosen. The latter characterizes the following complex indicators as the capacity of the hardware and software system when exchanging various types messages, the probability-time characteristics useful and service transport traffic, the reliability of the automotive service systems, and the protection information from unauthorized access to subscriber communication lines. The purpose this work is to study and analyze the effectiveness of the functioning of the information processing systems automotive service using next generation network technologies. As a result of the study, a mathematical model was proposed, which takes into account the nature of the transm?tted transport traffic and the presence multiple network resources, based on the performance indicators of the information processing systems. Analytical expressions are obtained, allowing to evaluate the indicators quality of service, information security and fault tolerance of the functioning of the system during the transfer various traffic. Based on numerical calculations, a graphical dependence of the average queue length of packets on the value of the system load factor was constructed. The graphical dependencies showed that the availability network resources leads to a significant improvement in the performance characteristics information flow processing systems.
Keywords: information processing systems, reliability, performance, fault tolerance, quality of service, security risk, average queue length.
