VirtuWind -基于SDN和NFV的软件化工业网络架构
VirtuWind - An SDN- and NFV-based Architecture for Softwarized Industrial Networks
摘要：
VirtuWind提出了软件定义网络（SDN）和网络功能虚拟化（NFV）在关键基础设施网络中的应用。我们的目标是在隔离和互连的工业网络中引入网络可编程性，可重新配置性和多租户能力。尽管如此，我们提出了VirtuWind架构的设计，解决了工业通信的要求：粒度服务质量（QoS）保证，系统模块化和安全和隔离的每租户网络访问。我们提出了我们的架构的功能组件，并提供了适当的实现机制的概述。最后，我们将两个示例性工业系统用例映射到所设计的架构，以展示其在示例性工业风电场网络中的适用性。
英文摘要：
VirtuWind proposes the application of Software Defined Networking (SDN) and Network Functions Virtualization (NFV) in critical infrastructure networks. We aim at introducing network programmability, reconfigurability and multi-tenant capability both inside isolated and inter-connected industrial networks. Henceforth, we present the design of the VirtuWind architecture that addresses the requirements of industrial communications: granular Quality of Service (QoS) guarantees, system modularity and secure and isolated per-tenant network access. We present the functional components of our architecture and provide an overview of the appropriate realization mechanisms. Finally, we map two exemplary industrial system use-cases to the designed architecture to showcase its applicability in an exemplary industrial wind park network.
