Embodiment 1

[0055] According to an aspect of the embodiments of the present invention, a system for obtaining data resources is provided, which is applied to a content distribution network based on P2P technology, including: a resource server and a terminal node, wherein,

[0056] The terminal node is used to send a data request to the resource server, wherein, the data request is used to request the resource identifier and node list of the data resource; the resource server is used to obtain the data request sent by the terminal node; according to the request parameters in the data request, Generate the resource identifier of the data resource; search according to the resource identifier to obtain the resource information of the data resource; the terminal node is also used to receive the resource information returned by the resource server according to the data request; generate a data download task according to the resource information, and execute the download.

[0057] Among them, the...

Embodiment 2

[0163] According to an embodiment of the present invention, an embodiment of a method for acquiring data resources is also provided. It should be noted that the steps shown in the flow charts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and , although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0164] The method embodiment provided in Embodiment 1 of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. Take running on a computer terminal as an example, Figure 4 It is a block diagram of the hardware structure of a computer terminal according to a method for acquiring data resources in an embodiment of the present invention. Such as Figure 4 As shown, the computer terminal 40 may include one or more (only one is shown in the ...

Embodiment 3

[0184] According to another aspect of the embodiments of the present invention, a method for obtaining data resources is also provided. In the terminal node, the present application provides the following Image 6 The method for obtaining the data resources shown. On the terminal node side, Image 6 It is a flowchart of a method for acquiring data resources according to Embodiment 3 of the present invention, including:

[0185] Step S602, the terminal node sends a data request to the resource server, wherein the data request is used to request the resource identifier and node list of the data resource;

[0186] Step S604, the terminal node receives the resource information returned by the resource server according to the data request;

[0187] Step S606, the terminal node generates a data download task according to the resource information, and executes the download.

[0188] To sum up, in combination with steps S602 to S606, the method for acquiring data resources provided...

Abstract

The invention discloses a data resource acquisition method, a device and a system. The method comprises the steps of acquiring a data request sent by a terminal node, and the data request, a resourceidentifier used for requesting data resources and a node list are acquired; generating a resource identifier of the data resource according to a request parameter in the data request; searching according to the resource identifier to obtain resource information of the data resource; and returning the resource information to the terminal node. The technical problem that in the prior art, in the resource updating process, dirty data are likely to be generated due to asynchronization of resource data updating is solved.

Description

technical field [0001] The present invention relates to the application field of Internet technology, in particular, to a method, device and system for acquiring data resources. Background technique [0002] In the content distribution network based on peer-to-peer computer network (peer to peer, referred to as P2P) technology, the problem of resource refresh is often involved, such as the update of the game upgrade package on the PC side, the distribution of the installation package apk in the Android application market, Video re-transcoding in video-on-demand. Before and after refreshing, because the resource has changed, but the URL has not changed, the old resource must be removed from the system and the new resource must be pushed down. During this process, it must be ensured that no dirty data exists. [0003] The biggest difference between content distribution based on P2P technology and traditional CDN is that P2P nodes are very scattered and highly dynamic. Nodes m...
