TSN industrial networking: evolution of Ethernet and IIoT To promote the shared network and accelerate products to market, industry is working toward a common technical platform including open source software, hardware reference designs, test plans and certification services to develop and verify the correct operation and implementation of TSN-enabled products. THE INDUSTRIAL INTERNET OF THINGS (IIoT) continues to grow. New capabilities and opportunity across industrial settings bring a need for streamlined operational and manufacturing models. As awareness surrounding IoT standardization continues to grow, more eyes are being drawn to the necessity of interoperability and network infrastructure solutions, including Time Sensitive Networking (TSN). Emerging TSN standards TSN is a standard from the IEEE that solves the need to process raw data in a time critical fashion, reducing latency while providing robustness, and ultimately creating a foundation for more advanced manufacturing and product models where data can be shared more flexibly between layers of the control system. These increased IoT infrastructure and network capabilities require a need for an interoperable ecosystem that allows for multiple manufacturers, protocols, and organizations to share the same TSN network, increasing productivity and ensuring network success. To prepare for this, Avnu Alliance selects and certifies a set of underlying mechanisms to meet a given market’s requirements, creating a common infrastructure that others can build on top of to enable convergence between Operational Technology (OT) and Information Technology (IT). This convergence increases connectivity to industrial devices and enables a faster path to new business opportunities including big data analytics and smart connected systems and machines. The Avnu Alliance is an industry alliance that fosters and develops an ecosystem of manufacturers providing interoperable devices for industrial networked systems. Made up of key technology and equipment providers, the industrial segment within Avnu includes member companies across the entire ecosystem and supply chain including IT vendors, silicon providers and industrial suppliers all working together to create an interoperable ecosystem of low-latency, time-synchronized, highly reliable networked devices. Avnu creates certification programs to ensure interoperability of networked devices for multiple markets and applications from machine control, health-care, smart grid and robotics to power generation, process control as well as automotive for the future of autonomous driving. Evolving Ethernet system designs Standard Ethernet has evolved to enable next generation control systems. With this, recent work by IEEE 802, the Internet Engineering Task Force (IETF), and other standards groups has extended the ability to operate timesensitive systems over standard Ethernet networks, supporting diverse applications and markets including professional audio/video, automotive, and industrial. These standards, driven primarily by the IEEE 802.1 Time-Sensitive Networking (TSN) task group, define new mechanisms for creating distributed, synchronized, real-time systems using standard Ethernet technologies that will allow convergence of low latency control traffic and standard Ethernet traffic 12 industrial ethernet book 4.2017 SOURCE: AVNU ALLIANCE Technology TSN ensures the predictable delivery of time-critical traffic and can also integrate with existing applications and standard IT traffic to strengthen interoperability.
