First plant-wide implementation of SDN in Japan


First plant-wide implementation of SDN in Japan

Yokogawa announces that it has completed the installation of a software-defined networking (SDN) solution at four paper plants in Japan that are operated by the Oji Group. According to Yokogawa, this is the first-ever plant-wide implementation in Japan of SDN, a software-based technology that enables the creation of virtual network environments.

With conventional plant networks, network devices (i.e., routers, firewalls) must be installed and configured for each individual application, location, and facility. The software-based SDN technology enables flexible implementation of virtual networks for each individual application, linking network devices using the same physical network. This facilitates the integrated management, implementation, and reconfiguration of networks. Also, this helps to reduce the required number of network devices and the amount of wiring that needs to be performed, saving both operating and management costs. Furthermore, the visualisation of network status leads to enhanced security. Problems can be easily identified, and network operators can remotely shut down specific segments of the plant network in the event of an emergency.

For this project, Yokogawa chose to use a proven SDN network device solution, NEC Corporation’s UNIVERGE PF series of controllers and switches. At each of this customer’s plants, Yokogawa assessed their IT infrastructure, including existing networks, and based on this assessment then designed and deployed its SDN technology solution.Yokogawa is also providing on a trial basis a security management service that monitors the status and health of the networks throughout these plants. While enabling timely preventive measures that help to maintain the health of the networks in these plants, this service also ensures that prompt actions can be taken in the event of an emergency.

In plants around the world, there is an increasing need to improve productivity, safety, and maintenance efficiency, and this is being achieved through the introduction of Industrial IoT (IIoT) technology. Networks help to create new value by connecting various types of devices, but it is essential to be able to flexibly change their configuration, quickly respond to surges in data volume, and ensure more secure operations. For the optimal implementation of IIoT technology, attention is now increasingly turning to the use of SDN technology in plant IT infrastructure.
