Problems solved by technology

[0003] However, when an existing file is uploaded, the transfer process needs to save the transfer status of the file. Therefore, the transfer status of the file cannot be obtained by other processes. If the transfer status of the file cannot be obtained, other processes cannot continue to upload, or re-upload
Therefore, a file can only be transmitted by one transmitting end and one receiving end, which affects the transmission rate

specific Embodiment 2

[0085] In another embodiment, the receiving end first obtains the number of transmitting ends that can be connected to it and the communication status of each transmitting end; then the information of the data block whose status is marked as unprocessed is grouped according to the aforementioned information, and sent to each transmitting end respectively . Specific Embodiment 1, the transmitting end A and the transmitting end B may communicate with the receiving end. The communication status between the transmitting end A and the transmitting end B is good. The receiving end divides the data block information whose status is marked as unprocessed into two groups, and sends them to the transmitting end A and the transmitting end B respectively. In the second specific embodiment, the transmitting end A, the transmitting end B, the transmitting end C and the transmitting end D can communicate with the receiving end. The communication status of transmitter A, transmitter B, and ...

Abstract

The embodiments of the invention disclose a file transmission method. The method comprises the following steps: receiving file information of a file to be transmitted, wherein the file information comprises a file length; according to the file length, creating a plurality of data block information for the file to be transmitted; receiving a data block information obtaining request; feeding the data block information in response to the data block information obtaining request; and receiving data blocks for the data block information. According to the embodiments of the invention, a file is segmented into the data blocks for transmission through creating the data block information. Furthermore, the data blocks can be transmitted through different transmitting ends so that the transmission rate is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of computer data transmission, and in particular, to a method, system and device for file transmission. Background technique [0002] With the development of computer technology and network technology, file transfer via network has become more and more common. [0003] However, when an existing file is uploaded, the transfer process needs to save the transfer status of the file. Therefore, the transfer status of the file cannot be obtained by other processes. If the transfer status of the file cannot be obtained, other processes cannot continue to upload, or re-upload. Therefore, a file can only be transmitted by one transmitting end and one receiving end, which affects the transmission rate. This problem is even more serious in the MOOC system. MOOC is a newly emerged online course development model, which developed from the past resource publishing, learning management system...
