Enhancing low‐priority traffic reconfiguration designs in mixed‐critical avionics networks

In avionics system networking, mixed-critical networks are commonly used to integrate applications with different levels of guarantees for various traffic classes on a shared resource platform, effectively addressing issues such as cabling, cost, weight, volume, power consumption, etc. However, current fault recovery and reconfiguration techniques mainly focus high-priority time-triggered (TT) traffic, often neglecting the impact TT low-priority traffic. This paper proposes an networking approach based IEEE 802.1CB protocol, which is shown be more effective post-failure Rate-Constrained (RC) (a typical type in networks). Furthermore, elastic algorithm presented ensure quality service RC during after reconfiguration, preventing arbitrary application shutdown triggered by reconfiguration. Simulations demonstrate that proposed can significantly improve ratio well guarantee network throughput certain extent.
