Time-Triggered EthernetAS6802A (Current)2/14/2023
This SAE Aerospace Standard (AS) defines a fault-tolerant synchronization strategy for building and maintaining synchronized time in a distributed system of end systems and switches (we use the term “end system” for data terminal equipment (DTE), as specified in IEEE 802.3), which can be used to support communication among these components for traffic, which may have different levels of time criticality. In particular, the standard defines algorithms for clock synchronization, clique detection, startup, and restart. These algorithms have been designed to allow scalable fault-tolerance and provide self-stabilization mechanisms. Time-triggered Ethernet supports the design of communication systems with mixed time criticality in which several applications of mixed time criticality share a single physical network. In particular, an Ethernet network can be used to transfer frames in a time-triggered mode (synchronous communication) and non-time-triggered modes (asynchronous communication as
