INTERCONNECTING CAN BUSSES VIA AN ETHERNET BACKBONE

In this paper, we compare different solutions for integrating existing data busses (such as CAN, which is an important standard in automotive context) on a global architecture that respects increasing bandwidth requirements and preserves the respect of real-time constraints. In a first step, we study classical CAN/CAN bridging strategies. In a second step, we propose CAN/Ethernet bridging strategies that respect the real time behaviour of CAN End System when communicating through an Ethernet network that is also shared by (non CAN) applications.
