摘　　要：随着SDN技术的不断发展,这一技术的思想逐渐被人们所接受,并且越来越多的应用在工业领域之中。但是在工业SDN架构下,难以解决PROFINET工业以太网协议在工业控制网络架构下的识别、解析以及处理问题,难以满足PROFINET工业以太网设备接入并建立通信关系等问题。因此本文设计了基于PROFINET工业以太网协议在工业SDN中的接入方法,包括PROFINET工业以太网协议在工业SDN交换机中的报文处理过程,PROFINET工业以太网协议在工业SDN控制器中的报文处理过程和PROFINET工业以太网设备接入处理过程,并指出了SDN中流表匹配项的具体匹配方式,为PROFINET工业以太网设备在工业SDN中的运行提供网络通信基础。从实际的执行效果上看,进一步提高了PROFINET工业以太网协议组网的使用效率和效果。With the continuous development of SDN technology, the idea of this technology is gradually accepted by people, and more and more applications in the industrial field. But in the industrial SDN architecture, it is difficult to solve the problems of identification, analysis and processing of PROFINET Industrial Ethernet protocol in the industrial control network architecture, and it is difficult to meet the problems of PROFINET Industrial Ethernet equipment access and establish communication relationship. Therefore, the paper designs the access method based on PROFINET Industrial Ethernet protocol in industrial SDN, including the message processing process of PROFINET Industrial Ethernet protocol in industrial SDN switch, the message processing process of PROFINET Industrial Ethernet protocol in industrial SDN controller and the access processing process of PROFINET Industrial Ethernet equipment, and points out the specific matching of stream table matching items in SDN. It provides the network communication foundation for PROFINET Industrial Ethernet equipment running in industrial SDN. From the actual implementation effect, it further improves the efficiency and effect of PROFINET Industrial Ethernet protocol networking.
