      The increasing number of driver assistance, infotainment and entertainment systems in automobiles results in higher requirements for bandwidth, fault tolerance and timing behaviour concerning the in-vehicle communication structure. In future, in-vehicle networks based on current technologies will reach their limits due to insufficient scalability and complexity. Real-time (RT) Ethernet is a new, scalable approach to reduce the complexity of these networks significantly. This paper demonstrates the architecture of a RT Ethernet prototype platform based on an ARM centred system-on-chip, which achieves timing and bandwidth characteristics of a typical future automotive application. It is based on an advanced interrupt driven architecture.

      Data networks of today's automobiles form a complex conglomerate of heterogeneously interconnected components. At the same time, high additional demands for future in-car communication systems are emerging from chassis control, camera based driver assistance and infotainment that cannot be accommodated by established technologies. A new approach towards a flexible highly scalable in-car network is real-time Ethernet. In this paper we discuss the upcoming requirements and argue why current in-car network designs are not suitable for future tasks. By demonstrating how a camera based time-critical driver assistance application can be integrated into a real-time Ethernet based in-car network, we present a typical use case for automotive broadband real-time communication and show application related design and configuration decisions.

In: 14th IEEE International Symposium on Object\addslash Component\addslash Service-Oriented Real-Time Distributed Computing Workshops (ISORCW) 2011.

      The performance analysis and validation of distributed real-time systems poses significant challenges due to high accuracy requirements at the measurement tools. A fully synchronized time-scale at ultrafine granularity is not easy to generate. Even though there are several analyzer tools for standard switched Ethernet, these tools cannot be applied in time-triggered networks, since they do not meet the requirements of synchronized packet generation. This paper introduces a low cost and lightweight approach to measure end-to-end latency of time-triggered Ethernet traffic with off-the-shelf components. By using standard computer hardware and a real-time Linux Kernel, it is shown that measurement can be achieved in a resolution of microseconds. Furthermore, a validation with an Ethernet performance analyzer and a mathematical framework is presented to check the given results.

    • Till Steinbach, Hermand Dieumo Kenfack, Franz Korf, and Thomas C. Schmidt. An Extension of the OMNeT++ INET Framework for Simulating Real-time Ethernet with High Accuracy.

      Real-time extensions to standard switched Ethernet widen the realm of computer networking into the time-critical domain. These technologies have started to establish in process automation, while Ethernet-based communication infrastructures in vehicles are novel and challenged by particularly hard real-time constraints. Simulation tools are of vital importance to explore the technical feasibility and facilitate the distributed process of vehicle infrastructure design. This paper introduces an extension of the OMNeT++ INET framework for simulating real-time Ethernet with high temporal accuracy. Our module implements the TTEthernet protocol, a real-time extension to standard Ethernet that is proposed for standardisation. We present the major implementation aspects of the simulation model and apply our tool to an abstract in-vehicle backbone. A careful evaluation that compares our results with calculations obtained from a mathematical framework, as well as with real-world measurements using TTEthernet hardware shows simulation and reality in good agreement.
