Abstract

An embodiment of the invention discloses a file receiving method. The file receiving method comprises the steps of receiving an index value sent by a transmitting terminal, wherein the index value is generated by the a first remote distribution server corresponding to the transmitting terminal after the first remote distribution server receives a target file uploaded by the transmitting terminal; extracting a file identifier data segment and a distribution address data segment in the index value; sending a download request comprising the file identifier data segment to a distribution server corresponding to the distribution address data segment; and receiving the target file corresponding to the file identifier data segment sent by the first remote distribution server. The invention also discloses a file receiving device and corresponding file transmitting method and device. Through adoption of the method, the bandwidth usage efficiency of a content distribution network can be improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a file sending method and device, and a file receiving method and device. Background technique [0002] In social networking applications, users can share pictures, music or video files with each other through instant messaging. For example, the user may use a camera to take a picture and share the picture file obtained by taking the photo with a friend, or the user may use a microphone to record and share the audio file obtained by the recording with a friend. [0003] In the traditional technology, when users share files between users, the user as the sharer usually does not send the file directly to the friend, but uploads the file to the distribution server first, obtains the storage path of the file on the distribution server, and then stores the file on the distribution server. The path is sent to the friend's terminal through the distribution server, and the terminal...
