A multi-network control framework based on industrial internet of things

In the industrial internet of things (IIoT), the coexistence of great deal of intelligent equipment and traditional network devices is universally found. Network has been transforming from single form into large-scale, heterogeneous networks. On such circumstance, traditional network standards and protocols fail to cope with the differences of the equipment. Moreover, there are inconveniences being found in the communication networks among multi-networks. This paper proposed a multi-network control framework based on industrial internet of things by the techniques of the software defined network and the virtualization. In this research, the differences of the equipment are masked. In addition, the flexible extension of network scale is realized through the dynamic extension and the collaborative sharing of virtual switches. A case shows the feasibility of the proposed framework.
