Simulation Modeling of Reliability of Packet Switching Unit

Abstract

Reliability analysis has been a hot research topic since the early 1960s. However, most of the methods were applied at the stage of software implementation. Reliability assessment at an early stage of system design is a faster formal method. It creates a probabilistic real-time system model and time property analysis based on schedule analysis. It proactively identifies potential security threats so costly changes are made during the system design phase. There is a lot of literature that mainly deals with the relationship between task priority and worst-case response time under a fault-tolerant state. Due to the growing security requirements of embedded software, many studies have emerged in the field of fault tolerance and reliability assessment. The traditional approach mainly relies on software testing bug data to predict future bug behavior. The issues of formalization of the problem of a complex hierarchical structure of real-time systems under conditions of a perturbing effect on the control object are considered, the parameters of the object under study are identified, and its simulation model is built.
