Embodiment
The solution of the embodiment of the invention mainly is: terminal sends the RARP probe messages that carries virtual mac address by the initial MAC Address of obtaining at random to the RARP server and broadcasts, inquire whether the MAC Address identical with virtual mac address is arranged in this subnet scoping, if the terminal of this MAC Address is arranged, then the RARP server can respond according to the RARP protocol specification, inform that this MAC Address of this terminal is in the subnet internal memory, if this terminal equipment repeatedly repeats to send the RARP probe messages, the RARP server does not all have response, the terminal of no similar MAC Address in this subnet then is described, then this virtual mac address is fixed use as real MAC address, reusable to guarantee MAC Address, avoid MAC Address to exhaust.
Related terminal is the network node of being close to the users in the network communication among the present invention, as gateway, smart phone, set-top box etc.
As shown in Figure 1, one embodiment of the invention proposes the multiplexing method of a kind of MAC Address, comprising:
Step S101, terminal sends the RARP probe messages by the initial MAC Address of obtaining at random to the RARP server, carries virtual mac address in the RARP probe messages;
Because in the prior art, MAC Address adopts the static allocation mode, MAC Address can't reclaim after the static allocation, cause MAC Address to be exhausted, present embodiment is considered that the MAC of the access device of terminal correspondence comes into force and is limited in scope and big characteristics of MAC Address amount that access device is shared, utilize the RARP agreement to carry out dynamic MAC and survey, reusable to guarantee MAC Address.
As shown in Figure 2, Fig. 2 is the position view of present embodiment terminal in network.The terminal of present embodiment is terminal equipment shown in Figure 2, in the network configuration at terminal place, comprises Access Layer, convergence-level and core layer, core layer Connection Service device side, and terminal connects core layer by access device.Wherein:
Access Layer refers to that direct user oriented connects or the part of accesses network; Convergence-level refers to connect the network equipment of Access Layer and core layer, for Access Layer provides the converging of data, transmits, management and distribution processor etc.; Server side refers to provide on the Internet network node group of various services.
Two characteristics of above-mentioned access device are embodied as:
1, the MAC of access device comes into force and is limited in scope, terminal equipment is present in Access Network, carries out routing forwarding by access device, at this moment, the MAC Address of terminal equipment can be access in the MAC Address of equipment and replace, namely MAC Address only access device among a small circle in come into force;
2, the shared MAC Address amount of access device is big, and often there are a plurality of connections in terminal equipment, and each connects needs different MAC Address, and the terminal equipment amount is big, often develop with quantity necessarily, like this, the needed MAC Address of terminal equipment is much larger than conventional equipment on the whole.
Therefore, according to above two characteristics, present embodiment utilizes the RARP agreement to carry out dynamic MAC and surveys, and detects the idle MAC Address of this Access Network, and carries out multiplexingly, uses the problem of exhausting to solve MAC Address.
At first, terminal sends the RARP probe messages by the initial MAC Address of obtaining at random to the RARP server and broadcasts, carry virtual mac address in this RARP probe messages, by whether the MAC Address identical with above-mentioned virtual mac address is arranged in the subnet scoping at this terminal place of broadcast polling.
Wherein, initial MAC Address is produced at random in advance by terminal and obtains.Present embodiment is adjusted into original terminal fixed MAC address the MAC Address of dynamic negotiation, but consider that message is in communication process, MAC Address is the underlying parameter of terminal positioning, when MAC Address was unconfirmed, the technical characterstic that message can't be transmitted adopted earlier with initial MAC Address as the basis, the constructing virtual MAC Address, and utilize RARP agreement detecting visual MAC Address whether to have the user using, thus find idle MAC Address resource, reach the reusable purpose of MAC Address.
Terminal generates the RARP probe messages according to the virtual mac address of the initial MAC Address that produces at random and structure, utilizes the RARP agreement that this RARP probe messages is sent to the RARP server.
Wherein, the structure of RARP probe messages comprises two necessary fields, initial MAC Address and type of message, and initial MAC Address is that terminal produces at random, and externally attempts, and is made up of 6 bytes; Type of message is used for this RARP probe messages of sign and belongs to RARP exploration type, and the length of this field and position and existing message link layer message field (MFLD) are in full accord, are made up of 2 bytes, are on existing message mechanism, the expansion on type of message.In addition, this RARP probe messages can also increase other fields, such as check code, filling and ageing time etc., but is not must parameter.

RARP allows the terminal of local area network (LAN) from ARP table or its IP address of buffer memory request of gateway server.The network manager creates a table with mapped physical address (MAC) and the IP address corresponding with it in the LAN gateway router.When a new terminal was set, its RARP client program need be to the corresponding IP of the RARP server request address on the gateway router.Suppose to be provided with in the routing table respective record, the RARP server then can return the IP address and give terminal.
The operation principle of RARP is as follows:
1, terminal sends the RARP message in the mode of broadcasting to the RARP server, in this broadcasting RARP message, states the MAC Address of oneself and asks any IP address of RARP server-assignment of receiving this request;
2, after the RARP server on the local network segment is received this request, check its RARP tabulation, search the IP address of this MAC Address correspondence;
If 3 exist, the RARP server then sends a response message to terminal, and this IP address is offered the terminal use; If there is no, the RARP server is not then done any response to this;
4, terminal is received from the response message of RARP server, utilizes the IP address that obtains to carry out communication; If never receive the response message of RARP server, then represent the initialization failure.
