Embodiment Construction

[0021] figure 1 It is a flow chart of Embodiment 1 of the data concurrent downloading method of the present invention, such as figure 1 As shown, this embodiment provides a method for concurrent data download, which may specifically include the following steps:

[0022] Step 101, analyze the file to be downloaded in the file server, and obtain the user information of the access user who has the access right to the file to be downloaded.

[0023] This embodiment is specifically applied in a wide area network optimization system, and files are downloaded concurrently through multiple links. This step is to analyze the file to be downloaded in the file server through the acceleration device set between the client and the egress gateway, obtain the file server where the file to be downloaded is located, and the access users who have access to the file to be downloaded user information. Among them, for different files to be downloaded, there are corresponding access rights of di...

Abstract

The invention provides a data parallel-downloading method, a data parallel-downloading apparatus and a network device. The method comprises the following steps: analyzing files to be downloaded in a file server, and acquiring user information of an accessing user with an access authority to the files to be downloaded; dynamically regulating the required links for downloading the files to be downloaded according to the running state of the device, the current bandwidth occupation condition and the user information of the accessing user; and downloading the files to be downloaded to a local device through the regulated parallel links. The invention further provides the data parallel-downloading apparatus and the network device. According to the data parallel-downloading method, the data parallel-downloading apparatus and the network device, the number of the parallel links can be dynamically regulated, and the file transmission efficiency is improved under a premise that the bandwidth is not excessively occupied.

Description

technical field [0001] The present invention relates to communication technology, in particular to a data concurrent download method, device and network equipment. Background technique [0002] File Transfer Protocol (File Transfer Protocol; hereinafter referred to as: FTP) is a common transfer protocol in the network, generally used for file sharing. FTP transmission is based on Transmission Control Protocol (Transmission Control Protocol; hereinafter referred to as: TCP), which has the characteristics of reliable transmission; FTP implementation is relatively simple, easy to deploy, and can set different access rights for different users. FTP can also perform two-way transmission, that is, the FTP client can download resources from the FTP site, and can also upload resources to the FTP site under the premise of obtaining corresponding permissions. Based on the above characteristics, FTP has become one of the main ways for specific institutions to share resources. At pres...
