Abstract

The invention discloses a file transmission method and system, a file sending device, and a file receiving device. The file transmission method comprises: receiving a file acquiring request carrying a file name and sent by a file receiving end; sending a file size corresponding to the file name to the file receiving end; receiving multiple data sending requests generated by the file receiving end according to the file size, wherein each data sending request carries the position of the requested data in a file; according to the data sending requests, sending corresponding data to the file receiving end in order that the file receiving end performs merging to generate the file according to the received data and the position of the data in the file. The invention also discloses another file transmission method and a device and system for implementing the same. According to the file transmission method, the file can be divided into multiple segments to be transmitted such that file transmission time is shortened and a probability of interruption and jamming in file transmission can be reduced. Therefore, file transmission efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a file transmission method and system, a file sending device and a file receiving device. Background technique [0002] The Internet is convenient, fast, and timely. Therefore, with the development of Internet technology, more and more people use the Internet to transfer files. [0003] Currently, Internet transmission links can include domestic links and international links according to regions. The adopted transfer protocols include File Transfer Protocol (File Transfer Protocol; FTP) and Hypertext Transfer Protocol (Hypertext Transfer Protocol; HTTP). Among them, the domestic link mainly serves the Internet transmission in the same country. In the same country, the Internet transmission protocol and the hardware required to be supported are exactly the same. Therefore, the national link transmission is also very stable. The international transmission link serves Intern...
