A distributed embedded system is the favorable choice of system implementation in a complex intelligent machine. On the one hand, most distributed systems have a certain network topology among their processing units. One such network topology, or communications backbone, is Ethernet. Ethernet has many advantages for employment on embedded systems, such as the fact that the transmission control protocol/ Internet protocol has been prevent to be robust over many years and is open to the technical community. As such, Ethernet is highly effective for unifying the system interface and reducing system complexity with its abundance of applications and tools. However, Ethernet devices need synchronization for purposes such as motor control and vision. Nevertheless, a study has been conducted by the International Electrotechnical Commission in Geneva to standardize the process for RT Ethernet, which is a promising Ethernet technology, to use Ethernet as a fieldbus alternative, encouraging the further establishment of the standards while maintaining the highest possible levels of flexibility.
