How can I get the most out of Automotive Ethernet?
System-level Network Simulation for the Design and
Evaluation of Upcoming Ethernet-based E/E Architectures



The introduction of Ethernet as a new automotive communication infrastructure is ex-pected to be an enabler for innovation. At the same time many important and complex questions for decision-makers, developers and integrators come up: How will future architectures look like? How can protocols support mixed-critical traffic (containing hard real-time control messages and multimedia data) on a single physical infrastruc-ture? How is reliability improved through redundancy? Are scheduled (IEEE 802.1Qbv) communication patterns required? Where are the limitations of different Ethernet based designs?
Simulation is a substantial element for providing a deep view into a system, and com-prehensive understanding about effects of processes inside a prototype that are usual-ly hidden. Using network simulation, the effect of central architecture decisions — such as traffic shaping, domain-specific partitioning, centralization of functions, or gateway forwarding strategies — can be made visible.
Network simulation is well known in the area of computer science. In the proposed talk we present the state of art in network simulation extended with our open source frameworks for heterogeneous in-car networks and explain why it is good practice to first simulate new network designs and protocols. Further we show how the knowledge obtained from simulation can be transferred into real-world prototypes and how the results obtained from these prototypes can be used to adapt the simulation.
We show how standardization efforts, such as the extensions defined in IEEE TSN for frame preemption (IEEE 802.3Qbu) and scheduled traffic (IEEE 802.3Qbv), can be accompanied by detailed assessments using realistic traffic patterns taken from series car communication matrices. Further we show how simulation can be used as a virtual test bed for strategies in upcoming applications, for example the smart aggregation of messages in gateways between CAN and Ethernet.
The goal of the presentation is to make developers and decision-makers aware of the extensive potential of network simulation during the design of next-generation Ethernet based in-car networks.
