Schedulability analysis for AFDX-based avionics systems

  • Avionics full duplex switched ethernet (AFDX) is designed for on-board communications in the new generation large aircraft. AFDX-based avionics systems are required to guarantee that hard real-time applications can be completed within their dead-lines. While current researches on real-time performance of AFDX only give the delay upper bound of frames,both the response-time of tasks in each processor and the delivery delay of hard real-time messages in AFDX networks were consided. The AFDX-based avionics system model was built, and the timing requirement of distributed task sequences was analyzed. Then, the worst case response time of task sequences was derived by using the holistic analysis. The proposed schedulability analysis provided a theoretical means to evaluate and optimize system real-time performance. Simulation results manifest that this analysis can give the tight upper bound for response time of task sequences.
