Embodiment 1

[0068] In this preferred embodiment, a MAC dynamic negotiation mechanism is provided. Through this mechanism, the static allocation of MAC addresses can be solved. MAC addresses are reusable. The MAC detection refers to the abbreviation of the MAC address dynamic negotiation protocol. The scheme is described in detail below.

[0069] In this preferred embodiment, by adjusting the fixed MAC address of the original device to a dynamically negotiated MAC address, but considering that the MAC address is the basic parameter for device positioning during the communication process of the message, when the MAC address is not confirmed , the technical feature that the message cannot be forwarded, adopts the first virtual MAC, and tries to use the mechanism to solve the contradiction that the MAC address is necessary in the process of message communication, but the MAC address needs to be negotiated.

[0070] The following describes in detail the message structure of the MAC explorati...

Embodiment 2

[0078] refer to Figure 11 The shown MAC detection process is described in detail, and the MAC detection protocol may include three steps:

[0079] Step S1102, the terminal device has a virtual MAC address, and constructs a MAC detection message, the source MAC is a virtual MAC address, the message type is a MAC detection type, and its identification code can be all zeros, and of course it can also be set to other values;

[0080] Step S1104, the message is sent repeatedly according to a certain time interval, and the virtual MAC address carried each time is different (in order to prevent the access device from receiving the virtual MAC address, it is also possible to send a message carrying the same MAC address within a certain time interval message, and send a message with a different MAC address after the time interval arrives), after the access device receives the message, it checks whether the MAC address exists in the MAC table it maintains. If it exists, it indicates I...

Abstract

The present invention discloses a MAC address control method and device, wherein the method includes: an access device receives a first MAC discovery message from a terminal device, wherein the first MAC discovery message carries a MAC address to be confirmed address; the access device judges whether the MAC address is available; if the judgment result is available, the access device sends a second MAC discovery message, where the second MAC search message is used to indicate that the MAC address is available. Through the present invention, the problem caused by the inability to reuse the MAC address in the related art is solved, and the MAC address is adjusted from static allocation to dynamic allocation, thereby fundamentally avoiding the waste and insufficient use of the MAC address.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for controlling a Media Access Control (MAC) address. Background technique [0002] With the explosive development of Internet information, a large number of terminal devices of various types appear, for example, terminal control devices such as home gateways, set-top boxes, and smart phones. These devices need to allocate corresponding identification resources on the Internet, for example, IP addresses, MAC addresses, and the like. Wherein, the MAC address refers to the device hardware address, which is used to define the location of the network device. At present, for IP addresses, the problem of insufficient IP addresses has been solved by gradually transitioning from IPv4 to IPv6 address mode; but for MAC addresses, it is originally planned to be a 48-bit address space, which is determined by each equipment provider in the production process. Applicatio...
