Embodiment 1

[0017] figure 1 It is a flow chart of the file transfer method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where two terminals using the same instant messaging software perform large file transfer. This method can be implemented by the first terminal and the The second terminal executes, wherein, the first terminal and the second terminal can transfer files by performing the following corresponding steps, and can also use the corresponding steps provided in this embodiment to cooperate with other file transfer methods. This method specifically comprises the following steps:

[0018] Step S110, the first terminal detects its own free port, and uses the detected free port to start the file transfer service used by the instant messaging software.

[0019] Specifically, when the instant messaging software starts running or after it starts running, the occupancy of each port is detected based on an instruction of the instant me...

Embodiment 2

[0044] In the case of the transmission interruption operation in the file transmission method provided by Embodiment 2 of the present invention, this embodiment is based on the above-mentioned embodiments, preferably during the file fragment download process, when the first user operates the first terminal and clicks the pause button, Or when the button is cancelled, the first terminal receives the suspension instruction and sends it to the second terminal through the file transmission channel. Alternatively, when the second user operates the second terminal to click a pause button or a cancel button to abort the operation, the second terminal receives the abort instruction and sends it to the first terminal through the file transmission channel. When the first terminal receives the suspension instruction, it will stop sending each file segment. At the same time, when the second terminal receives the suspend instruction, it stops acquiring the downloaded data of each file segm...

Embodiment 3

[0054] figure 2 The structure diagram of the file transfer system provided by Embodiment 2 of the present invention is applicable to the situation where two terminals using the same instant messaging software perform large file transfer. This method can be implemented by the first terminal and the The second terminal executes, wherein, the first terminal and the second terminal can transfer files by executing the following corresponding modules, and can also use the corresponding modules provided in this embodiment to cooperate with other file transfer methods. The system includes a first subsystem and a second subsystem. Wherein, the first subsystem is installed in the first terminal, and the second subsystem is installed in the second terminal. The first subsystem includes: a service startup module 11 , a first file transmission channel establishment module 12 , and a first download module 13 . The second subsystem includes: a second file transmission channel establishmen...

Abstract

The invention discloses a file transmission method and system. In the method, the first terminal detects its own free port, and utilizes the detected free port to start the file transfer service used by the instant messaging software; utilizes the file transfer service to establish a point-to-point file with the second terminal A transmission channel; wherein, the second terminal is determined according to the file transmission operation on the user information in the instant messaging software. The second terminal feeds back a segment download request to the first terminal according to the information of the file to be transmitted obtained from the first terminal; uses the file transmission channel to obtain each file segment, and divides each downloaded file into segments The files are synthesized into corresponding files to be transmitted. The invention solves the problem that a third-party server is required for file transmission, and effectively improves the speed of data transmission. In addition, the files to be transmitted are transmitted in pieces, and the data transmission speed is further improved through parallel transmission.

Description

technical field [0001] Embodiments of the present invention relate to network data transmission technologies, and in particular to a file transmission method and system. Background technique [0002] Instant messaging technology provides people with a way of text communication anytime and anywhere. With the development of instant messaging technology, people can not only chat with text at any time, but also chat with voice and video. [0003] In addition, people use the instant messaging technology to transfer files and other attachments, which provides people with a new file transfer method. [0004] At present, the transmission of files by instant messaging mostly requires the use of remote servers to forward files, which makes file transmission slow due to the influence of the link bandwidth of the two links: the sending terminal-server and the server-receiving terminal. [0005] In order to solve the above problems, technicians refer to the file upload and download tec...
