Industry 4.0 introduces modern communication and computation technologies such as cloud computing and Internet of Things to industrial manufacturing systems. As a result, many devices, machines, and applications will rely on connectivity, while having different requirements to the network, ranging from high reliability and low latency to high data rates. Furthermore, these industrial networks will be highly heterogeneous, as they will feature a number of diverse communication technologies. Current technologies are not well suited for this scenario, which requires that the network is managed at an abstraction level, which is decoupled from the underlying technologies. In this paper, we consider network slicing as a mechanism to handle these challenges. We present methods for slicing deterministic and packet-switched industrial communication protocols, which simplify the manageability of heterogeneous networks with various application requirements. Furthermore, we show how to use network calculus to assess the end-to-end properties of the network slices.

工业 4.0 应用中的网络切片：抽象方法和端到端分析


工业4.0将云计算、物联网等现代通信和计算技术引入工业制造系统。因此，许多设备、机器和应用程序将依赖于连接性，同时对网络有不同的要求，从高可靠性、低延迟到高数据速率。此外，这些工业网络将是高度异构的，因为它们将采用多种不同的通信技术。当前的技术不太适合这种场景，这需要在抽象级别上管理网络，与底层技术解耦。在本文中，我们将网络切片视为应对这些挑战的机制。我们提出了切片确定性和分组交换工业通信协议的方法，这些方法简化了具有各种应用需求的异构网络的可管理性。此外，我们还展示了如何使用网络演算来评估网络切片的端到端属性。
