Abstract
Systems and methods for implementing controller area network (CAN) communications between CAN nodes using Ethernet are provided. An Ethernet switch includes ports, each of which is configured to receive an Ethernet data packet (EDP) from a CAN node. Each EDP includes a CAN message, which includes an identification (ID) of a corresponding CAN node. A first port is configured to receive a first EDP and a second port is configured to receive a second EDP. The Ethernet switch also includes a controller module configured to detect a CAN conflict between the first EDP and the second EDP. The controller module is configured to select, in response to the detection of the CAN conflict, the first EDP or the second EDP based on the ID corresponding to the first EDP and the ID corresponding to the second EDP. The controller module is configured to route the selected EDP to a destination.
