Problems solved by technology

[0004] However, because the prior art file distribution control center evenly distributes all files in the servers of each node, some cold-spot files may not be accessed for a long time, while some hot-spot files or super-hot-spot files will be accessed at the same time. Multiple requests lead to unbalanced access pressure on the content distribution system, resulting in system overload and unreasonable utilization of system resources

Embodiment 1

[0062] The embodiment of the present invention provides a CDN file storage method, which can be applied to a content distribution system, such as figure 1 As shown, CDN file storage methods include:

[0063] S101. The file distribution control center acquires the file to be stored.

[0064] CDN is a layer of intelligent virtual network on the basis of the existing Internet, which is formed by placing node servers all over the network. In the prior art, one node of the content distribution system can cover multiple servers, and the file distribution control center determines which files are stored in which servers of which nodes. Generally, the file distribution control center will distribute as many files as possible to the servers of each node, so that users all over the country can obtain the files needed by the users nearby. However, since the file distribution control center in the prior art evenly distributes all files in the servers of each node, some cold-spot files m...

Embodiment 2

[0081] The embodiment of the present invention provides a CDN file storage method, which can be applied to a content distribution system, such as figure 2 As shown, CDN file storage methods include:

[0082] S201. The file distribution control center acquires first data.

[0083] In the prior art, one node of the content distribution system can cover multiple servers, and the file distribution control center determines which files are stored in which servers of which nodes. Generally, the file distribution control center will distribute as many files as possible to the servers of each node, so that users all over the country can obtain the files needed by the users nearby. However, since the file distribution control center in the prior art evenly distributes all files in the servers of each node, some cold-spot files may not be accessed for a long time, while some hot-spot files or super-hot-spot files may be accessed at the same time. In the case of multiple requests, the...

Embodiment 3

[0122]Embodiments of the present invention provide a file distribution control center, which is applied to a content distribution system, such as image 3 As shown, the file distribution control center includes:

[0123] The first obtaining module 10 is used to obtain the file to be stored.

[0124] The judging module 11 is used for judging the type of the file to be stored, wherein the type of the file to be stored is a cold spot file, a hot spot file or a super hot spot file.

[0125] The first sending module 12 is configured to send a first file storage message to a storage node if the file to be stored is the cold spot file, so that a server of the storage node stores the cold spot file.

[0126] The second sending module 13 is configured to send a second file storage message to the storage node and edge node if the file to be stored is the hotspot file or the super-hotspot file, so that the storage node and the edge node can communicate with each other. The edge node st...

Abstract

The embodiment of the invention provides a CDN file storage method, a file distribution control center and a system thereof, and relates to the field of network multimedia technology. According to the invention, reasonable storage modes can be flexibly allocated for files according to types of the files. Thus, visit pressure of a content distribution system is balanced; system resources are utilized reasonably; network congestion is relieved; system overloads are avoided; and performance of a CDN system is raised. The method comprises the following steps: the file distribution control center acquires files to be stored; the file distribution control center judges types of the files to be stored; if the files to be stored are cold-spot files, the file distribution control center sends a first file storage message to a storage node so as to make a server of the storage node store the cold-spot files; and if the files to be stored are hotspot files or ultra-hotspot files, the file distribution control center sends a second file storage message to the storage node and an edge node so as to make the storage node and the edge node store the hotspot files or ultra-hotspot files.

Description

technical field [0001] The invention relates to the technical field of network multimedia, in particular to a CDN file storage method, a file distribution control center and a system. Background technique [0002] CDN (Content Delivery Network, Content Delivery Network) is a layer of intelligent virtual network on the basis of the existing Internet formed by placing node servers everywhere in the network. CDN can redirect the user's request to the service node closest to the user according to the comprehensive information such as network traffic and connection of each node, load status, distance to the user and response time in real time. The nodes send the content required by the user to the user, relieve the congestion of the network, and improve the response speed of the website. [0003] In the prior art, one node of the content distribution system can cover multiple servers, and the file distribution control center determines which files are stored in which servers of ...
