预防性和反应性维护需要从工业工厂和其他复杂系统(如基于机器人细胞的系统)收集越来越多的信息，这一需求可以通过适当的事件通知机制来满足。同时，与其他情况相比，这些情况下的时间和交付可靠性要求通常较低，因此能够采用尽力而为的通知方法。本文基于标准的控制器局域网(CAN)消息传递或最近提出的具有可扩展帧内应答的CAN协议扩展(CAN XR)，对其中的一些方法进行了介绍、评估和比较。在第二种情况下，组合使用Bloom Filters也被设想为增加灵活性。结果表明，后一种方法在一系列具有实际意义的事件生成率和网络拓扑结构中具有优势。
Preventive and reactive maintenance require the collection of an ever-increasing amount of information from industrial plants and other complex systems such as those based on robotized cells, a need that can be fulfilled by means of a suitable event notification mechanism. At the same time, timing and delivery reliability requirements in those scenarios are typically less demanding than those in other cases, thus enabling the adoption of best-effort notification approaches. This paper presents, evaluates, and compares some of those approaches, based on either standard Controller Area Network (CAN) messaging or a recently proposed protocol extension called CAN with eXtensible in-frame Reply (CAN XR). In the second case, the combined use of Bloom filters is also envisaged to increase flexibility. Results show that the latter approaches are advantageous in a range of event generation rates and network topologies of practical relevance.
