Embodiment Construction

[0042] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0043] Such as figure 1 As shown, the present invention designs a data copy storage method for cloud computing content distribution network. In the actual application process, wherein the cloud computing content distribution network includes a source server node and at least two edge server nodes, the source server The nodes store the entire network data files and data file copy list, and the data file copy list stores preset data file copies to be stored and their corresponding data sizes; the cloud-oriented content distribution network also includes a global copy storage edge server node set , wherein, each element of the set respectively represents the edge server node that has been used to store the copy of the data file; the data copy storage method, for each copy of the data file to be stored in the copy list of th...

Abstract

The invention relates to a data copy storage method for a cloud computing content distribution network. For data file copies, the transmission cost of the data file copy from the source server node to the edge server node and the cost of the data file copy on the edge server node are considered comprehensively. Place the cost and the storage cost of the data file copy on the edge server node, combined with the cost generated when the edge server node serves as the service center to provide services to all other edge server nodes, select the optimal edge server node for copy storage of the data file copy , so that the copy of the data file can realize efficient data call operation in the cloud computing-oriented content distribution network.

Description

technical field [0001] The invention relates to a data copy storage method for a cloud computing content distribution network, and belongs to the technical field of cloud computing and data copy placement. Background technique [0002] With the continuous development of the Internet, on the one hand, the content on the network has developed from the original static pictures and texts to multimedia services; on the other hand, the number of users continues to increase, and the frequency of content requests also increases. Longer questions. Under the above-mentioned problems, content distribution network (CDN) solves this kind of problem comprehensively technically, and is more and more widely used at home and abroad. However, the existing CDN architecture also has its prominent problems. In the face of a sharp increase in business volume, the prominent problem is the lack of IT infrastructure and storage space. At the same time, the current CDN model cannot meet the ever-ch...
