Abstract :
Data Distribution Service (DDS) middleware has become one of the best solutions for real-time distributed industrial systems. An interesting innovation would be the use of the DDS middleware on top of Ethernet networks to enhance the performances of automobile applications. In this paper, we will introduce the use of DDS on top of Ethernet networks and propose as a testing application an extended SAE (Society of Automotive Engineers) benchmark. The main aim is to be able to calculate the worst case response time (WCRT) based on a scheduling model, and using it as a metric to evaluate the respected of DDS real-time QoS (Quality of Service). The results obtained by using Ethernet are compared to the results found using FlexRay.
