The invention relates to a data transmission method and device based on industrial Ethernet and communication equipment. The method comprises: mapping a port according to configuration information ofindustrial equipment, and the configuration information comprising an MAC address of the industrial equipment; receiving an access request message which is transmitted by the network side and comprises the MAC address of the industrial equipment by adopting the mapped port, and analyzing the access request message; verifying the access request message according to the analyzed message content; andwhen the verification is passed, sending an access request message to the industrial equipment. According to the method, the MAC address of the industrial equipment is mapped to the communication equipment through address mapping, the communication equipment has the same MAC address as the industrial equipment, so that the communication equipment is responsible for communicating with a network side, and the industrial equipment is invisible at the network side. Therefore, the security of the industrial equipment is effectively improved, and the privacy of data is ensured.
Description
technical field [0001] The present application relates to the technical field of communication, in particular to an industrial Ethernet-based data transmission method, device and communication equipment. Background technique [0002] With the development of communication technologies, Ethernet networks are widely used in industrial scenarios. More and more devices can be interconnected through the network. Such as figure 1 As shown, according to the traditional network architecture, by directly connecting the industrial equipment 10 to the network, the server or remote client 20 can directly access the industrial equipment 10 connected to the network through the network. [0003] However, the industrial devices 10 connected to the network are vulnerable to network attacks, resulting in low system security. Contents of the invention [0004] Based on this, it is necessary to provide an industrial Ethernet-based data transmission method, device, and communication device t...
