ABSTRACT
Time-triggered protocol (TTP) is a high-speed, masterless, multicast, dual-channel 25 Mbit/s field bus communication protocol for safety-critical embedded applications in the transportation industry. TTP communication controllers provide built-in health monitoring, system synchronization, and redundancy services for straightforward development of fault-tolerant embedded systems. A network designed with TTP guarantees manageable modular system design, simplified application development with minimized integration effort, strictly deterministic communication and new levels of safety at lower total life-cycle costs. TTP enables the development of physically distributed, but fully integrated, time-triggered architectures (TTAs) for modern avionics or aerospace control systems. Hence, the development of distributed safety-critical, hard real-time computing and networking for smart control systems (see Figure 4.1) in “more electric” or “all electric” aircraft is fully supported.
