¿µ¹®³»¿ë¿ä¾à The standard describes message format and signaling of logical time synchronization for distributed embedded systems. Legacy real-time and embedded systems have been small scale and standalone. However, they are increasingly being connected to create large-scale distributed system recently. But the verification complexity increases in practice as several factors such as delay, jitter and error. An equivalent synchronized execution of distributed tasks are required in distributed real-time system. Our method is based on the PALS which is a complexity-reducing architectural pattern for distributed real-time systems. Section 5 describes reference model for message format. In the section 7, the reference model for signaling and APIs for logical time synchronization
