NODE DEVICE ACCESS METHOD, SYSTEM AND APPARATUS BASED ON MAC ADDRESS

摘要

A node device access method, system and apparatus based on a MAC address. In the method, a first node device receives a MAC conflict detection packet sent by a newly added node device; determines, according to locally saved MAC addresses of other node devices in a network where the first node device is located, whether a MAC address of the newly added node device conflicts with the MAC addresses of the other node devices; when a conflict exists, stops forwarding the packet; and when no conflict exists, saves the MAC address, and adds a timestamp for receiving the packet to the packet and forwards the packet. In embodiments of the present invention, each node device saves MAC addresses of other node devices in a network where the node device is located; therefore, when the node device receives a MAC conflict detection packet, the node device can make overall judgment according to the condition in the network, and the access efficiency of the node device can be improved; in addition, when no conflict is detected, a timestamp is added to the packet, so that follow-up MAC address counterfeit detection can be facilitated, and the security of the system is improved.
