Description
Technical Field
The present invention relates to an ethernet access technology, and in particular, to a method, an apparatus, and a system for allocating Medium/Media Access Control (MAC) addresses.
Background
At present, the Internet is an Internet Protocol Version 6 (IPv 6) network, and with the development of network technologies such as smart cities, electronic earth, and the Internet of things, the demand of people for accessing the IPv6 network at any time and any place is continuously expanding, and various wired and wireless terminal devices are continuously accessing the IPv6 network. Moreover, with the development of virtualization technology, virtual terminal devices are also continuously added to the IPv6 network. However, the MAC address of the conventional terminal device is a 48-bit address generated by random solidification at the time of shipment, and thus is not changeable. As the number of terminal devices accessing the two-layer switching network increases, the probability that different terminal devices have the same MAC address increases, which may result in MAC address collision.
Because the packet forwarding of the layer two switch is realized based on the MAC address, when the MAC address conflicts exist in the layer two switch network, the MAC forwarding table may oscillate, which may cause the layer two switch to mistakenly send the service response interaction message, the service access message, and other messages, which may further cause the terminal device with the MAC address conflicts to fail to normally access the network, and may not provide the network service for the user.
In addition, since the message of network interaction is guided to another device with conflicting MAC by the layer two switch, not only the risk of leakage of network secret information is caused, but also the risk of network attack is caused to be guided to an undesired terminal device or a virtual device, thereby bringing about the risk of network attack.
