Problems solved by technology

[0008] In the above process, each node device can judge whether the MAC address carried in the MAC conflict detection message conflicts with its own MAC address only when it receives the MAC conflict detection message sent by the newly added node device. Only node devices with MAC address conflicts can determine whether the MAC addresses conflict. Therefore, the MAC address detection method when the node device in the prior art is connected is a waste of time and cannot effectively improve the efficiency of MAC address detection.

Abstract

The present invention provides a MAC address-based node device access method, system and device. In the method, the first node device receives a MAC conflict detection message sent by a newly added node device, and according to other The MAC address of the node device, judge whether it conflicts with the MAC address, stop forwarding the message when there is a conflict, save the MAC address when there is no conflict, and add the timestamp of receiving the message to the message and forward it . Because in the embodiment of the present invention, each node device stores the MAC addresses of other node devices in its network, after receiving the MAC conflict detection message, it can make an overall judgment according to the situation in the network, thereby improving In addition, when no conflict is detected, adding a time stamp to the message can facilitate subsequent MAC address counterfeiting detection, thereby improving system security.

Description

technical field [0001] The invention relates to the technical field of industrial Ethernet communication, in particular to a MAC address-based node device access method, system and device. Background technique [0002] At present, industrial Ethernet is developing very rapidly and has been widely used in various industries, so that the status of Ethernet communication in the field of industrial automation has risen rapidly. [0003] figure 1 When a new node device in the prior art is connected to the network, the MAC address conflict detection process includes the following steps: [0004] Step 1: The newly added node device sends a MAC conflict detection (ARP) message to the whole network, wherein the MAC conflict detection message carries the MAC address information of the newly added node device. [0005] Step 2: Other node devices that have received the MAC conflict detection message judge whether the MAC address information conflicts with their own MAC address accordi...
