Abstract
A method can comprise determining, by a device comprising a processor, a transition between an arbitration phase of a Controller Area Network (CAN) XL node of a group of communicatively coupled CAN XL nodes of a CAN bus network and a data phase of the CAN XL node based on a voltage change of a voltage level of the CAN XL node being determined, by device, to satisfy a defined voltage change criterion of defined voltage criteria, wherein the data phase comprises both positive voltages and negative voltages, and in response to determining the transition, routing, by the device, dominant data or logic 0/1 data of the CAN XL nodes to other nodes of the group of CAN XL nodes.
