Dynamic management of reconfigurable industry 4.0 real-time communication networks using Software-defined infrastructure (DynSDN) (T03#)

时间敏感网络（TSN）是一种网络技术，它代表了工业自动化领域中工业、异构通信网络融合的基本构建块。在具有异构需求和共享网络资源的动态环境中提供与上下文无关的高通信质量是合作研究中心SFB 1053“MAKI -未来互联网多机制适应”的目标。SFB 1053内的这个转移项目的目标是使时间敏感网络中的服务质量控制的交换模型和编程架构成为可能。我们的目标是利用SFB 1053中正在开发的转换概念，为建立在动态SDN基础设施之上的TSN应用程序实现网络资源优化和容错。转换在这里被理解为可编程网络基础设施元素（例如交换机）的重新配置，以满足运行在TSN上的自动化应用程序的服务质量标准。该项目的成果将通过使用TSN实现工业应用的实时功能来展示。

Time-Sensitive Networking (TSN) is a networking technology that represents an essential building block for the convergence of industrial, heterogeneous communication networks in the field of industrial automation. The provisioning of a context-agnostic high communication quality in a dynamic environment with heterogeneous requirements and shared network resources is the goal of the collaborative research center - SFB 1053 "MAKI - Multi-Mechanisms Adaptation for the Future Internet". The goal of this transfer project within the SFB 1053 is to enable switch models and programming architectures for Quality-of-Service control in Time-Sensitive Networks. Our aim is to enable a network resource optimization and fault tolerance for TSN applications built on top of dynamic SDN infrastructures using the concept of Transitions which is being developed within the SFB 1053. Transitions are to be understood here as reconfigurations of the programmable network infrastructure elements, e.g. switches, in such a way that Quality-of-Service criteria of the automation applications running over TSN are met. Results of this project will be shown through realizations of real-time functions of industrial applications using TSN.
