Problems solved by technology

[0006] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide a control / management method, system, readable storage medium and equipment for transferring files, which are used to solve the unreliable broadcasting of actual wireless channels in the prior art. The time sensitivity of different types of files is different, and the coding guidelines of the file request in the coding process are not considered, and the time-sensitive transmission is not satisfied. The inevitable retransmission strategy increases the traffic burden of the wireless network.

Embodiment 1

[0045] This embodiment provides a method for controlling file transfer, which is applied to an ad hoc network including several clients and servers; the method for controlling file transfer includes:

[0046] Classify files according to file type;

[0047] Send a file transfer request;

[0048] While sending the file transfer request, a retransmission time is generated, and the file corresponding to the file transfer request is not received within the generated retransmission time, and the file transfer request is resent; wherein, the retransmission time is the same as The file type is related to the transfer process.

[0049] The method for controlling file transfer provided by this embodiment will be described in detail below in conjunction with illustrations. The control method for transferring files provided in this embodiment is applied to such as figure 1 In the shown ad hoc network 1 , the ad hoc network 1 includes several clients 11 and servers 12 . Files are trans...

Embodiment 2

[0080] This example provides a Figure 5 , is a schematic diagram showing the interaction between the file transfer control system and the file transfer management system in an embodiment. It should be noted that it should be understood that the division of the various modules of the control system for transferring files and the management system for transferring files above is only a division of logical functions, which can be fully or partially integrated into a physical entity during actual implementation, or can be physically on separate. And these modules can all be implemented in the form of calling software through processing elements; they can also be implemented in the form of hardware; some modules can also be implemented in the form of calling software through processing elements, and some modules can be implemented in the form of hardware. For example, the x module can be a separate processing element, and can also be integrated in a chip of the above-mentioned de...

Embodiment 3

[0094] This embodiment provides a device, including: a processor, a memory, a transceiver, a communication interface, and a system bus; the memory and the communication interface are connected to the processor and the transceiver through the system bus to complete mutual communication, and the memory is used to store computer The program, the communication interface is used to communicate with other devices, the processor and the transceiver are used to run the computer program, so that the device executes the various steps of the control method for transferring files as described above, or makes the device execute the steps of the management method for transferring files as described above various steps. Wherein, the device executing the method for controlling file transfer is a client, and the device executing the method for managing file transfer is a server end.

[0095] The system bus mentioned above may be a Peripheral Component Interconnect (PCI for short) bus or an Ext...

Abstract

The present invention provides a control / management method, system, readable storage medium, and device for transferring files, which are applied to an ad hoc network including several clients and servers; the method for controlling file transfer includes: classifying files according to file types ; Send a file transfer request; while sending the file transfer request, generate a retransmission time, and do not receive the file corresponding to the file transfer request within the generated retransmission time, and resend the file transfer request; wherein, The retransmission time is related to the file type and the transmission process. Aiming at the wireless ad hoc network coding scheme, the present invention rationally selects the time factor in the coding buffering process, which not only satisfies the time-sensitive transmission, but also reduces the traffic burden of the wireless network.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a control / management method and system, in particular to a control / management method, system, readable storage medium and equipment for file transmission. Background technique [0002] With the development of mobile Internet networks, requests for multimedia content greatly increase the burden on wireless networks. In addition, the quality of people's multimedia requests is increasing, which further intensifies the demand for wireless network throughput. An effective way to reduce the burden on the wireless network is to add a storage function to the network nodes to store files that may be requested by the client. This is the caching technology. The proposal of caching technology allows clients to request files locally without directly requesting to the remote server. Combined with local caching technology, encoding caching is proposed. The encoding cache not only ...
