Embodiment Construction

[0035] The solution of the embodiment of the present invention is mainly as follows: the terminal sends the RARP detection message carrying the virtual MAC address to the RARP server through the initial MAC address obtained randomly to broadcast, and inquires whether there is a MAC address identical to the virtual MAC address in the subnet range. address, if there is a terminal with this MAC address, the RARP server will respond according to the RARP protocol specification, telling the terminal that the MAC address is already in the subnet memory, if the terminal repeatedly sends RARP detection messages, the RARP server will If there is no response, it means that there is no terminal with a similar MAC address in the subnet, and the virtual MAC address will be used as a real MAC address to ensure that the MAC address can be reused and avoid MAC address exhaustion.

[0036] The terminals involved in the present invention are network nodes close to users in network communication,...

Abstract

The invention relates to a method, terminal and system for reusing an MAC address. The method comprises the steps that the terminal sends RARP detection messages to an RARP server through an initial MAC address which is obtained arbitrarily, and the RARP detection messages carry a virtual MAC address; if the terminal repeatedly sends the RARP and after a preset frequency is reached, the response messages of the RARP server are not received at all, and then the virtual MAC address is used as a real MAC address to conduct normal communication. According to the method, terminal and system for reusing the MAC address, based on a dynamic negotiation mechanism of the MAC address of an RARP protocol, the MAC address is automatically generated, static allocation of the MAC address is adjusted to be dynamic allocation, and the problems that the MAC address is wasted and not enough to use is solved fundamentally.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, terminal and system for multiplexing MAC (Media Access Control, Media Access Control) addresses based on RARP (Reverse Address Resolution Protocol, reverse address translation protocol). Background technique [0002] With the development of Internet technology, a large number of various types of terminal devices have emerged, such as home gateways, set-top boxes, smart phones and other terminal control devices. These devices need to allocate corresponding identification resources on the Internet, such as IP addresses and MAC addresses. For the IP address, the IPv4 address mode has been gradually transitioned to the IPv6 address mode, which has solved the problem of insufficient IP addresses. However, for the MAC address, the original 48-bit address space is to be applied by each equipment provider in the production process. Afterwards, address conflicts a...
