Ethernet is being considered as the backbone network protocol for next-generation automotive control networks. In such networks, Controller Area Network (CAN) messages related to automotive control can be sent from a CAN network to other sub-networks via the backbone Ethernet bus and, if the CAN messages have real-time constraints, these have to be guaranteed. This paper presents a simulation environment for CAN--Ethernet Audio Video Bridging (AVB) mixed networks based on OMNeT++. We use Ethernet AVB, which can guarantee network bandwidth, to improve the real-time property of CAN messages through the backbone Ethernet bus. To simulate the networks, we also developed a CAN--Ethernet AVB gateway (GW) model. To verify the efficacy of our model, we measured the latency of CAN messages sent from a CAN bus to an Ethernet AVB node via the backbone Ethernet AVB bus in both bandwidth-guaranteed and best-effort queue scenarios. The results indicate that the latency of Ethernet AVB frames containing CAN messages is minimized and limited by the bandwidth-guaranteed mechanism of Ethernet AVB.
