Dual-Plane Switch Architecture for Time-Triggered Ethernet

Time-triggered Ethernet (TTE) technology introduces the concept of time-triggered on the basis of traditional Ethernet, so that it can achieve conflict-free and deterministic service forwarding without sacrificing compatibility. However, storage resources in industrial, aviation, aerospace and other equipment are limited. Therefore, it is important for TTEthernet to develop switching technologies with high storage efficiency and scalability. This paper proposes a dual plane switching (DPS) architecture for TTEthernet, which divides time-triggered services and event-triggered services into two planes for data forwarding. Experimental results show that using the TTE switch of this architecture has the advantages of high clock synchronization accuracy, high throughout, low transmission delay and small jitter of TTE service.
