[en] This work is about the design and configuration of service-oriented communication on top of Ethernet TSN. The first objective is to present takeaways from the design and implementation of the Renault E/E Service-Oriented Architecture (SOA) called FACE. In particular, we discuss technological, design and configuration choices made for the SOA, such as how to segment messages (UDP with multiple events, TCP, SOME/IP TP), and the technical possibilities to shape the transmission of the packets on the Ethernet network.
The second objective is to study how to ensure the Quality of Service (QoS) required by services. Indeed, services introduce specific challenges, be it only the sheer amount of traffic they generate and if there is a growing body of experiences in the use of TSN QoS mechanisms most of what has been learned so far is mostly about meeting the requirements of individual streams. Less is known for services that involve the transmission of several, possibly segmented, messages with more complex transmission patterns. We show on the FACE architecture how SOME/IP messages were mapped to TSN QoS mechanisms in a manual then automated manner so as to meet the individual requirements of the services in terms of timing, and the system’s requirements in terms of memory usage.
