An in-vehicle ethernet network design and implementation with TSN

With the increasing performance requirements for the IVN (in-vehicle network), the automotive Ethernet is gradually being applied in high bandwidth sub-networks with the help of an AVB (Audio Video Bridging) standard set. To support control and safety-critical data, TSN (Time-Sensitive Networking, the next generation of AVB) is proposed to provide deterministic services for IEEE 802 networks, and many research studies have shown its excellent performance with the help of simulation and calculation tools. In the case of applying the Ethernet for IVN subnets and backbones, it is expected to have a similar or better level of performance compared with the CAN bus. This paper describes one approach to build a real automotive Ethernet network with flow control, real-time and redundancy abilities in TSN. The network topology, traffic streams, hardware/software development and validation are presented to show the process during the invehicle Ethernet network development. The results show that the expected performance of the automotive Ethernet network can be reached with proper network design and node implementation. © 2018 Indian Pulp and Paper Technical Association.
