Exploiting real-time switched ethernet for enhanced network recovery scheme in naval combat system

Switched Ethernet has been used widely in industrial applications because of its high speed and deterministic characteristics. This paper proposes an enhanced network recovery (ENR) scheme based on switched Ethernet to handle network failures in the naval combat system. In this study, network failure recovery is explained through message scheduling on switched Ethernet, which is based on previous works on flexible time trigger (FTT) Ethernet. The proposed ENR method expands the previous works by adding a spanning tree construction, failure detection, recovery switching, a repeated message scheme and system robustness. To show the advantages of the ENR scheme, the performance of the proposed method is compared with the performance of the existing protocol called Time-Triggered Ethernet (TTEthernet). The simulation results show that the proposed ENR scheme outperforms the TTEthernet.
