过去二十年来，控制器局域网络 (CAN) 一直是汽车行业事实上的标准，最近具有灵活数据速率的 CAN 已实现标准化，可实现更高的速度。通过利用 CAN 特有的物理层在网络节点之间执行分布式操作，可以进一步改进。本文提出了对 CAN 协议进行扩展的建议，表示为具有可扩展帧内回复功能的 CAN (CAN XR)，它使上层协议层能够定义新的自定义服务，专用于网络管理、特定于应用程序的功能和高效数据传输等。由于CAN XR保留了与CAN FD的完全向后兼容性，因此无需更改协议规范。
Controller Area Network (CAN) has been the de facto standard in the automotive industry for the past two decades, and recently CAN with flexible data-rate has been standardized, which achieves higher speed. Further improvements are possible by exploiting the peculiar physical layer of CAN to perform distributed operations among network nodes. In this paper a proposal is made for an extension to the CAN protocol, denoted CAN with eXtensible in-frame Reply (CAN XR), which enables upper protocol layers to define new custom services devoted to, e.g., network management, application-specific functions, and high-efficiency data transfer. Since CAN XR retains full backward compatibility with CAN FD, there is no need to change the protocol specification.
