End-to-end delay analysis in an Integrated Modular Avionics architecture
Résumé
Recent modular avionics architectures have been designed to share computation and communication resources. However, such an approach creates new challenges to master the temporal properties of avionics applications. In the context of IMA (Integrated Modular Avionics), it is crucial to investigate the performance gains that future integration platforms and software will propose. This paper brings to light the impact of spatial and temporal integration choices on the communication performance (e.g. message loss rate, latencies, ...). The conclusion of this investigation is that it is necessary to conduct a thorough modeling and simulation study of an IMA architecture integrating several applications during its early design stages.
