Time-Triggered Ethernet (TTE) is a state-of-the-art networking technology designed for deterministic real-time communication over Ethernet. It integrates seamlessly with existing Ethernet infrastructure, providing fault-tolerant solutions for critical systems in aerospace, automotive, and industrial applications. TTE simplifies the design of networks by maintaining safety and redundancy at the network level, thus easing the application design processes. It ensures precise traffic scheduling, allowing for the integration of tight control loops and the certification of safety networks. TTE's ability to offer replicated packet communication guarantees message transmission even in fault scenarios, enhancing system availability and simplifying failure management.
