Embodiment 1

[0036] The embodiment of the present invention provides a data distribution method, which uses the proxy ARP technology to distribute the IP data of the data source according to its destination IP, and distributes it to different frequency channels for transmission, thereby solving the problem of insufficient frequency resources of a single channel.

[0037] Such as figure 1 As shown, the method described in this embodiment includes the following steps:

[0038] Step S101, the network device broadcasts an ARP request message in the local area network to find the desired target device;

[0039] Step S102, the wireless sending device responds to the ARP request message by proxy ARP, and sends the data source sent by the network device to the wireless receiving device based on each supported channel;

[0040] Step S103, after receiving the data source, the wireless receiving device broadcasts an ARP request message, searches for a target device specified by the data source, and ...

Embodiment 2

[0052] An embodiment of the present invention provides a data distribution method, which discloses more technical details to describe the method of the present invention in more detail.

[0053] The system structure of the application of the method described in this embodiment is as follows: figure 2 shown. figure 2 Among them, network device 1 and network device 2 want to send data to the wireless transmitter 1 and wireless transmitter 2 of the wireless sending device through the network switch, and the wireless sending device sends the data to the wireless receiver 1 and wireless receiving device of the wireless receiving device. Machine 2, and then send to network devices 3, 4, 5, 6 through the network switch.

[0054] It is assumed that the channel bandwidth of the wireless transmitter 1 is limited and not enough to transmit the network data sent from the network device 1 to the network devices 3, 4, 5. However, the wireless transmitter 2 has redundant channel resource...

Embodiment 3

[0071] An embodiment of the present invention provides a wireless sending device, including:

[0072] The data distribution module is configured to respond to the ARP request message by proxy ARP when receiving the ARP request message broadcast by the network device, and send the data source sent by the network device based on each supported channel to the wireless receiving device.

[0073] Specifically, in the embodiment of the present invention, the data distribution module includes multiple wireless transmitters supporting different channel bandwidths.

[0074] At this time, one or more wireless transmitters in the data distribution module respond to the ARP request message using the MAC address of the local machine as the MAC address of one or more target devices queried by the network device. Further, each wireless transmitter of the data distribution module sends the data source sent by the network device to the wireless receiving device after receiving the data source...

Abstract

The invention discloses a data distribution method, device and system. The method comprises the following steps that: network equipment broadcasts an ARP request message in a local area network in order to find required target equipment; wireless transmission equipment makes a response to the ARP request message in a proxy ARP way, and transmits data sources transmitted by the network equipment to wireless receiving equipment on the basis of supported channels; and after reception of the data sources, the wireless receiving equipment broadcasts the ARP request message, finds target equipment specified by the data sources, and transmits the data sources to the target equipment. According to the method, IP data of the data sources are distributed to channels with different frequencies to be transmitted according to a destination IP of the IP data through a proxy ARP technology, so that the problem of insufficient frequency resources in a single channel is solved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a data distribution method, device and system. Background technique [0002] With the development and popularization of wireless communication technology, frequency resources have become one of the main restrictive factors that limit the transmission data bandwidth. [0003] When the spectrum resources are limited and the available spectrum is discontinuous, for example, the usable A bandwidth α~β, and the usable B bandwidth θ~λ, the wireless transmission device using the A bandwidth is device A, and the wireless transmission using the B bandwidth The device is device B. At this time, if the amount of data transmitted by the data source still exceeds the data bandwidth that can be carried by the frequency spectrum of each device after being compressed, coded and modulated by the existing technology, it is necessary to apply for more spectrum bandwidth resources respe...
