Embodiment 1

[0036] figure 1 It is a flowchart of a method for accessing and scheduling data in a CDN in a preferred embodiment of the present invention; the method includes the following steps:

[0037] S101. Receive media file request information;

[0038] In the embodiment of the present invention, the CDN network system has two levels of nodes in total, that is, the source station and the second-level node; each node includes at least one media server and one storage server;

[0039] The media server is used to process media requests sent by end users, record media file information, classify and schedule access to media files, etc.;

[0040] The media file information includes creation time, number of visits, frequency of visits, and rating of visit popularity;

[0041] The access heat classification includes infrequently accessed files, frequently accessed files, and hot files, and the access heat increases sequentially; it is set by the user according to the access times and access...

Embodiment 2

[0054] figure 2 It is a structural diagram of a data access and scheduling system in a CDN in a preferred embodiment of the present invention; the system includes a media server and a media file storage server,

[0055] The media server includes:

[0056] A media file request receiving module, configured to receive media file request information;

[0057]The media file information management module is used to record the media file information, and the media file information includes creation time, access times, access frequency, and access heat classification; the access heat classification includes non-frequently accessed files, frequently accessed files, and hotspot files, The popularity of visits increases in turn; it is set by the user according to the number of visits and visit frequency of the media file.

[0058] Scheduling module, for regularly checking the storage status of media files; if the media files are non-frequently accessed files, then the media files will...

Abstract

The invention discloses a data access and scheduling method in CDN, and a system. According to the method, access times and access frequency of media files are recorded, access heat of the media files is divided, corresponding media file storage strategies and corresponding scheduling methods are employed according to different media file access heat, an IO bottleneck problem caused by access of multiple media servers to one storage server is solved. Through the method, a disk IO and network IO contradiction problem can be effectively solved, and upgrade cost can be controlled to a maximum degree.

Description

technical field [0001] The invention relates to the technical field of CDN data scheduling, in particular to a data access and scheduling method and system in a CDN. Background technique [0002] The rapid development of the Internet has brought great convenience to people's work and life, and the requirements for Internet service quality and access speed are getting higher and higher. Although the broadband is increasing and the number of users is also increasing, the load of the server Influenced by factors such as transmission distance and transmission distance, the response speed will be slower. The solution is to use network caching technology in network transmission to enable nearby access to service data streams, globally load balance traffic, and optimize network data transmission, thereby obtaining high-speed experience and quality assurance. This is the basic idea of ​​CDN content delivery network. [0003] With the growth of the overall scale of Internet users i...
