Problems solved by technology

If the folder contains a lot of content, it will take a long time for the two communicating parties to compress and decompress it, resulting in a long wait for response time, which may affect the user experience

Embodiment 1

[0036] see figure 1 , figure 1 It is a flowchart of a method for implementing data download provided in Embodiment 1 of the present invention. The method for implementing data download may specifically include:

[0037] Step 110, receiving a download request message sent by the request node, the download request message carrying the identifier of the target directory requested by the request node for download;

[0038] Specifically, based on different communication protocols, the data format of the download request message may be different. The communication protocol based on data upload or download in the embodiment of the present invention may be, Hypertext Transfer Protocol (HTTP, Hypertext Transfer Protocol), file Transmission protocol (FTP, File Transfer Protocol), point-to-point protocol (PPP, Peer-Peer Protocol), etc., but not limited thereto.

[0039] For example, the identification of the above-mentioned target directory (or called: request directory) can be: the na...

Embodiment 2

[0048] The scheme of this embodiment corresponds to data downloading. see figure 2 , figure 2 It is a flowchart of a method for implementing data download provided in Embodiment 2 of the present invention. The method for implementing data download may specifically include:

[0049] Step 201, the first node sends a download request message to the second node;

[0050] Wherein, the data format of the download request message corresponds to the communication protocol for data transmission between the first node and the second node. The information carried in the above download request message includes, but is not limited to: the identification of the target directory that the first node requests to download. The data format of the identification can be agreed upon by the first node and the second node and correspondingly recorded. The identifier corresponds to the target directory that the first node requests to download.

[0051] Step 202, the second node generates descrip...

Embodiment 3

[0110] The solution in this embodiment corresponds to data upload. see image 3 , image 3 It is a flowchart of a method for implementing data upload provided by Embodiment 3 of the present invention. The method for implementing data upload may specifically include:

[0111] Step 301, the first node generates description information corresponding to each file and / or directory under the source directory;

[0112] The above-mentioned source directory can be regarded as the directory to be uploaded by the first node, and the source directory can include multiple files and / or directories.

[0113] Specifically, the first node may traverse the source directory to generate description information corresponding to each file and / or directory in the source directory.

[0114] Wherein, similarly, the description information of the file may include, but not limited to: the relative path information of the file relative to the source directory, the length information of the relative pa...

Abstract

The embodiment of the invention discloses a method, a network node and a communication system for realizing data downloading and uploading. In the technical scheme of the invention, through generating description of each file and / or catalog under a request catalog and combining description and file content of the file under the request catalog and / or description of the catalog into data stream, as well as data stream combined by direct transmission of two parties of communication, a receiver can directly retrieve the request catalog based on description of the data stream; the process of compressing and decompressing the request catalog can be left out on the two parties of communication, thus can effectively lower complexity of calculation, shorten waiting responsive time and promote user experience.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method for realizing data download and upload, a network node and a communication system. Background technique [0002] In today's network environment, nodes on the network often transmit data to each other to achieve the purpose of data sharing. For example, users (clients) often download or upload text files, picture files, audio and video files, and program files to the server from the server. [0003] At present, the following situations exist in the data transmission between nodes: that is, node A (for example, client) requests to download the folder (also called: directory) b1 on node B (for example, server), and folder b1 contains multiple files and / or directories; after node B receives the download request message from node A, it first compresses the folder b1 into a compressed file, and then sends the compressed file to node A; after node A receives the compressed fi...
