Data distribution service timing and buffering management for Ethernet

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. In this paper, we will establish timing and buffering management system to launch listeners related to timing communication status representing real-time QoS (Quality of Service). We will use as a testing application an extended SAE (Society of Automotive Engineers) benchmark to calculate the worst case response time (WCRT) based on the full scheduling model, and to introduce it into the DDS QoS to prove that these real-time QoS are respected.
