Accurate Reliability Allocation Algorithm of Airborne FC Network Based on Analytic Hierarchy Process

As the backbone data network of integrated modular avionics system, the reliability of Fibre Channel network has a great influence on the reliability of the system. At present, network reliability allocation only considers hardware devices, which cannot accurately allocate the reliability index of airborne FC network. This paper analyzes the characteristics of FC airborne network and the influencing factors of node reliability, and propose the model and calculation method of FC network node comprehensive importance based on the analytic hierarchy process. By using AGREE method, an accurate network reliability allocation algorithm is designed, and the reliability allocation of non-redundancy and double redundancy FC network nodes is completed. The verification results show that compared with the traditional reliability allocation method, the reliability allocation method in this paper has the advantages of comprehensive factors, high allocation accuracy and strong practicability.
