近年来，考虑到实时性和高可靠性等问题，将价格较低、速度较高的以太网技术应用于测控系统中的控制器网络，发展了一种被称为“工业以太网”的技术。目前，国际电工委员会（IEC）正在进行“实时以太网（RTE）”的标准化工作。与现有的工业以太网相比，RTE的一个显著特点是具有使每个节点之间的定时同步的机制，并且能够进行确定性通信（每个节点之间的同步精度在规范中定义）。本文介绍了RTE国际标准化的最新进展，并介绍了该标准定义的性能指标。此外，我们解释的技术趋势，有关时间同步和高可用性的冗余，然后我们介绍了有关RTE规范的大纲。近年来，有可能成为“事实上的标准”的规范得到国际标准化，并迅速成为“法律上的标准”，这一点非常重要。关注未来国际标准化的发展趋势，研究最新技术的发展趋势，也将变得非常重要
In recent years, the technology called "industrial Ethernet" in consideration of the problems such as real-time and high reliability is developed to apply the lower price and higher speed Ethernet technologies to the controller networks in the measurement and control systems. At present, in IEC (International Electrotechnical Commission), the standardization working of "real-time Ethernet (RTE)" is progressed. Compared with existing Industrial Ethernet, it is a remarkable feature that RTE has the mechanism which synchronizes the timing between each node, and enables deterministic communication (synchronization accuracy between each node is defined in the specifications). In this paper, we update the latest information on the RTE international standardization, and introduce the performance indicators defined by the standard. Furthermore, we explain the technical trend regarding time synchronization and high availability by redundancy, and then we introduce the outline regarding the RTE specifications. Recently it is important that the specification which might become "De-facto Standard" is internationally standardized and turns into "De-jure Standard" promptly. It will also become very important to watch the trend of international standardization in the future, in order to research the trend of the latest technology
