虚拟化技术在新型工业自动化中的应用：催化剂还是阻止剂？
Application of Virtualization Technologies in Novel Industrial Automation: Catalyst or Show-Stopper?
摘要：
工业4.0描述了一种自适应和可变的生产，其中其工厂单元必须以非常短的间隔重新配置，例如在每个工件之后。此外，这种情况不能用传统设备（例如可编程逻辑控制器）来实现。在这里，使用经过验证的信息技术正在征服生产大厅（IT-OT融合）。因此，虚拟化和新型通信技术都被引入工业自动化领域。此外，这些技术被视为促进各种新兴用例的关键。然而，目前尚不清楚每个专用硬件和软件组件是否可以在不进行重大调整的情况下进行升级，这些组件是为特定控制任务开发的，并且几十年来表现良好。在本文中，我们将根据工业应用的严格要求，分析硬件和操作系统级虚拟化的机遇和挑战。为此，通过确定不同虚拟化技术的计算和网络开销、配置工作量、可访问性、可伸缩性和安全性来设置不同虚拟化技术的基准。
英文摘要：
Industry 4.0 describes an adaptive and changeable production, where its factory cells have to be reconfigured at very short intervals, e.g. after each workpiece. Furthermore, this scenario cannot be realized with traditional devices, such as programmable logic controllers. Here the use of well-proven technologies of the information technology are conquering the production hall (IT-OT convergence). Therefore, both virtualization and novel communication technologies are being introduced in the field of industrial automation. In addition, these technologies are seen as the key for facilitating various emerging use cases. However, it is not yet clear whether each of the dedicated hardware and software components, which have been developed for specific control tasks and have performed well over decades, can be upgraded without major adjustments. In this paper, we examine the opportunities and challenges of hardware and operating system-level virtualization based on the stringent requirements imposed by industrial applications. For that purpose, benchmarks for different virtualization technologies are set by determining their computational and networking overhead, configuration effort, accessibility, scalability, and security.
