- Timo Häckel, Philipp Meyer, Franz Korf, and Thomas C. Schmidt. SDN4CoRE: A Simulation Model for Software-Defined Networking for Communication over Real-Time Ethernet. In: Proceedings of the 6th International OMNeT++ Community Summit. 2019,
[Abstract], [ArXiv], [Bibtex]Ethernet has become the next standard for automotive and industrial automation networks. Standard extensions such as IEEE 802.1Q Time-Sensitive Networking (TSN) have been proven to meet the real-time and robustness requirements of these environments. Augmenting the TSN switching by Software- Defined Networking functions promises additional benefits: A programming option for TSN devices can add much value to the resilience, security, and adaptivity of the environment. Network simulation allows to model highly complex networks before assembly and is an essential process for the design and validation of future networks. Still, a simulation environment that supports programmable real-time networks is missing. This paper fills the gap by sharing our simulation model for Software-Defined Networking for Communication over Real-Time Ethernet (SDN4CoRE) and present initial results in modeling programmable real-time networks. In a case study, we show that SDN4CoRE can simulate complex programmable real-time networks and allows for testing and verifying the programming of real-time devices.

Schmidt. DoS Protection through Credit Based Metering - Simulation Based Evaluation for Time-Sensitive Networking in Cars. In: Proceedings of the 6th International OMNeT++ Community Summit. 2019,
[Abstract], [ArXiv], [Bibtex]Ethernet is the most promising solution to reduce complexity and enhance the bandwidth in the next generation in-car networks. Dedicated Ethernet protocols enable the real-time aspects in such networks. One promising candidate is the IEEE 802.1Q Time-Sensitive Networking protocol suite. Common Ethernet technologies, however, increases the vulnerability of the car infrastructure as they widen the attack surface for many components. In this paper proposes an IEEE 802.1Qci based algorithm that on the one hand, protects against DoS attacks by metering incoming Ethernet frames. On the other hand, it adapts to the behavior of the Credit Based Shaping algorithm, which was standardized for Audio/Video Bridging, the predecessor of Time-Sensitive Networking. A simulation of this proposed Credit Based Metering algorithm evaluates the concept.

Simulation of Mixed Critical In-vehicular Networks. In: Recent Advances in Network Simulation. Pages 317—345, 2019, Springer,
[Abstract], [Online], [ArXiv], [Bibtex]Future automotive applications ranging from advanced driver assistance to autonomous driving will largely increase demands on in-vehicular networks. Data flows of high bandwidth or low latency requirements, but in particular many additional communication relations will introduce a new level of complexity to the in-car communication system. It is expected that future communication backbones which interconnect sensors and actuators with Electronic Control Units (ECUs) in cars will be built on Ethernet technologies. However, signaling from different application domains demands for network services of tailored attributes, including real-time transmission protocols as defined in the Time-Sensitive Networking (TSN) Ethernet extensions. These Quality of Service (QoS) constraints will increase network complexity even further. Event-based simulation is a key technology to master the challenges of an in-car network design. This chapter introduces the domain-specific aspects and simulation models for in-vehicular networks and presents an overview of the car-centric network design process. Starting from a domain-specific description language, we cover the corresponding simulation models with their workflows and apply our approach to a related case study for an in-car network of a premium car.

[Abstract], [Fulltext Document (pdf)], [Bibtex]In dieser Arbeit wird ein Algorithmus zur Erkennung und Klassifizierung von Fahr- spurmarkierungen aus LiDAR-Daten entwickelt. Damit dieser für die Umsetzung eines Autobahnpiloten genutzt werden kann, muss er robust sein und außerdem in Echtzeit auf einer NVIDIA AGX Xavier Platform laufen. Um dies zu erreichen wird der Algorithmus auf einer GPU beschleunigt und optimiert. Die mittlere Laufzeit konnte dabei auf 7 ms reduziert werden, ohne Robustheit einzubüßen. Es wird darauf geachtet, dass der Algorithmus leicht erweiterbar ist und schnell an veränderte Voraussetzungen angepasst werden kann.

Anhand der Virtual Local Area Networks (VLAN) soll untersucht werden, wie sich die Kommunikation in einem gemeinsamen Netzwerk sowohl zwischen priorisierten echtzeitbasierten Anwendungen als auch nicht-priorisierten echtzeitbasierten Anwendungen verhält. Es soll dabei analysiert werden, ob der nicht-priorisierte zeitkritische Cross-Traffic Auswirkung auf die Echtzeitfähigkeit des Systems hat. Des Weiteren wird geprüft, ob die priorisierten Nachrichten durch den Cross-Traffic beeinflusst werden. Dazu werden die Latenz sowie der daraus berechnete Jitter untersucht.

Piscataway, NJ, USA, Apr. 2019, IEEE Press,
[Abstract], [Online], [Fulltext Document (pdf)], [Bibtex]Future in-vehicular networks will be based on Ethernet. The IEEE Time-Sensitive Networking (TSN) is a promising candidate to satisfy real-time requirements in future car communication. Software-Defined Networking (SDN) extends the Ethernet control plane with a programming option that can add much value to the resilience, security, and adaptivity of the automotive environment. In this work, we derive a first concept for combining Software-Defined Networking with Time-Sensitive Networking along with an initial evaluation. Our measurements are performed via a simulation that investigates whether an SDN architecture is suitable for time-critical applications in the car. Our findings indicate that the advanced control overhead of SDN can be added without a delay penalty for the TSN traffic when protocols are mapped properly.
