      Investigations into the usage of Ethernet in automobiles is in progress in academia, the car industry and companies producing automotive electronic devices. The interest in Ethernet is motivated by the high bandwidth and scalability provided. It is a well experienced technology with support for the Internet Protocol (IP) suite. Ethernet as in-car network is expected to breakthrough in Advanced Driver Assistance Systems (ADAS) involving cameras and in the multimedia domain. Both the IEEE Audio Video Bridging (AVB) standard and Time-Triggered Ethernet (TTE) are promising candidates. This paper presents a simulation study aimed to investigate the behavior of these technologies when supporting ADAS and multimedia traffic on star-based networks under varying workload. The performance under different operating conditions is presented and discussed.

    • Florian Bartols. Cluster Simulation of Real-time Ethernet based Electronic Control Units in Context of Automotive Applications: Extending FIBEX for Real-time Ethernet. Sep. 2012,
      [Abstract], [Bibtex]

      The increasing complexity of automotive networks and their high bandwidth requirements will demand new concepts in networking of electronic automotive components. TTEthernet is a suitable candidate to solve this problem. In order to allow testing of control units in an early point in the development process, cluster simulation has been established as an adequate manner and therefore in this project it is developed for Real-time Ethernet using the example of TTEthernet. This work realizes a FIBEX extension for TTEthernet and presents an approach for model-to-model transformation of the proprietary TTEthernet-Network-Description to the developed FIBEX extension.

    • Till Steinbach, Hyung-Taek Lim, Franz Korf, Thomas C. Schmidt, Daniel Herrscher, and Adam Wolisz. Tomorrow's In-Car Interconnect? A Competitive Evaluation of IEEE 802.1 AVB and Time-Triggered Ethernet (AS6802). In: 2012 IEEE Vehicular Technology Conference (VTC Fall). Piscataway, NJ, USA, Sep. 2012, IEEE Press,

      Ethernet-based in-car communication is currently a hot topic in the automotive industry. Soon Ethernet will start to oust MOST bus in its domain of info- and entertainment applications. However, the full benefit of a technologically integrated in-car network will only become rewarding with the deployment of an Ethernet-based backbone that integrates all automotive domains on a single layer at increased bandwidth, reduced complexity and cost, while opening car intelligence for future innovations. Such backbone must transport critical control data in real-time. Standard Ethernet requires extensions to comply with the strict timing requirements of driver assistance and safety applications while simultaneously supporting broadband multimedia traffic. In this paper, we compare IEEE 802.1 AVB and Time-triggered Ethernet, two competing real-time approaches. While the first fosters over- provisioning and prioritisation, the second is based on a coordinated time-division-multiple-access (TDMA) policy for media access. By simulating a realistic in-car backbone design and traffic model, we reveal the strengths and weaknesses of both protocols and point to the diverging characteristics of event- and time-triggered policies. Our results show that in this in-car network scenario both protocols are able to meet the rigid timing requirements, while each has its unique benefits and disadvantages.
