Design And Implementation Of Industrial Internet Of Things Dynamic Transmission And Calculation Framework Based On Software Defined Network

With the rapid development of the Internet of Things technology,more and more fields have been combined with the Internet of Things technology,and then they are moving towards digital and intelligent trends.Among them,the field of Industrial Internet of Things has developed rapidly in recent years,but the traditional network architecture obviously cannot meet the management requirements of a large number of sensor nodes in Industrial Internet of Things.Software defined network,a new network architecture opens up new possibilities.This paper combines software defined network with the Industrial Internet of Things,uses software defined network controllers and virtual switches to build a network environment suitable for the Industrial Internet of Things,and implements a dynamic transmission and calculation framework for configurable process.The dynamic transmission and calculation framework in this paper is built on the basis of software defined network,and the hosts are connected through virtual switches.All hosts are controlled by the controller of the software defined network.The instructions realize the interaction between the software defined network control layer and the data layer.At the same time,this paper designs one kind of transmission and calculation configuration for coordinating transmission and calculation processes between different devices.In the transmission and calculation configuration,you can select the calculation function to be performed and the specific device responsible for execution.Through the generation and distribution of the confi guration,the coordination of the transmission and calculation process is realized.At present,two file compression algorithms and one target detection algorithm have been used to test the dynamic transmission and calculation framework as optional calculation functions.The dynamic transmission and calculation framework adopts a modular design and can be divided into a user interaction module,a dynamic configuration module,a data acquisition module,a virtual switch module,and a result processing module from top to bottom.Through the collaboration between the functional modules,the working mode of coherent calculation through transmission has been realized.At present,it has been practically deployed and applied in the factory environment.
