ABSTRACT
The Time-Triggered Architecture (TTA) [1-3] is a distributed computer architecture for the implementation of highly dependable real-time systems. In particular, it targets embedded control applications, such as by-wire systems in the automotive or aerospace industry. For these safety-critical systems fault tolerance is of utmost importance. The Time-Triggered Protocol (TTP/C) constitutes the core of the communication level of the TTA. It furnishes a number of important services, such as atomic broadcast, consistent membership, and protection against faulty nodes that facilitate the development of these kinds of fault-tolerant real-time applications.
