Problems solved by technology

However, if there are multiple routers and slow links between the sender and the receiver, this connection method will seriously reduce the throughput of the request. This is a single Transmission Control Protocol (TransmissionControl Protocol; hereinafter referred to as: TCP) Due to the sliding window limitation that is easy to appear in the request, due to the limitation of the TCP sliding window, when the browser uploads file data through a single channel, it cannot maximize the use of network bandwidth resources, which will consume more time when uploading file data

Abstract

The invention provides a file uploading method and device. The file uploading method comprises the steps that a file uploading notification sent by a server is received; according to the file uploading notification, if the size of the file is larger than that of predetermined fragments, fragmentation cutting is conducted on the file according to the predetermined fragments, and at least two fragments of the file are acquired; and the fragments are uploaded to the server in parallel through at least two channels. According to the method, a browser can upload the file to the server through at least two channels, network bandwidth resources can be utilized maximally, and the file uploading speed is increased; and in addition, the server can discrete the file uploaded by the browser through a Hash value corresponding to the file, and then breakpoint resume and second transmission functions of the file can be achieved.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular to a method and device for uploading files. Background technique [0002] In the related art, uploading a file through a web browser generally submits the file through a Hypertext Markup Language (Hypertext Markup Language; hereinafter referred to as: HTML) web form, and uploads the file to a server for storage. [0003] Submitting files through an HTML web form generally uses a browser to upload file data through a single channel. This upload method does not support breakpoint resume uploads. In the case of network interruption or network fluctuations in transmission, the upload process will be interrupted and must be re-uploaded. File data, especially in the process of uploading large files, is more likely to be interrupted, but cannot be resumed from the interruption, thus wasting a lot of time and traffic for users. [0004] In addition, the sliding window protoc...
