Abstract

The invention relates to an SDN (Software Defined Network)-based heterogeneous network data flow reconstruction method in an intelligent factory. The method comprises the following steps: S1, acquiring data transmission request information of current source equipment; s2, obtaining address parameters and network parameters of the source device and the target device according to the data transmission request information; and S3, according to the network parameters of the source device and the target device, corresponding data flow construction is carried out according to different data flow modes. According to the heterogeneous network data flow reconstruction method in the intelligent factory based on the SDN, the data flow in the intelligent factory is redesigned and defined according to the particularity of different data forwarding and processing processes, and compared with a traditional data flow priority mode, the information interaction efficiency of the heterogeneous data flow is improved, the average transmission delay is reduced, and the data flow reconstruction efficiency is improved. And the transmission performance is better in a complex industrial network environment.

Description

technical field [0001] The invention belongs to the technical field of intelligent manufacturing, and in particular relates to a method for reconstructing heterogeneous network data streams in an SDN-based intelligent factory. Background technique [0002] In the context of Industry 4.0, the demand for data exchange between intelligent manufacturing devices in the Internet of Things continues to grow, while the fixed hierarchical network structure (OSI / ISO seven-layer architecture) in traditional networks has become an obstacle to the further development of the Internet of Things. People have proposed a new concept for the industrial production environment by introducing software-defined networking (SDN), that is, the software-defined industrial Internet of Things to make industrial networks more flexible. The core idea of ​​SDN perfectly solves the limitations of traditional networks, decoupling network data forwarding and network control, and directly opening programmable ...
