Streaming media file intelligent scheduling method, equipment and computer program product

Abstract

The invention relates to an intelligent scheduling method and device for streaming media files and a computer program product. According to the method and the device, the characteristics of different CDN service providers can be utilized to cooperate with multiple CDN service providers to perform global scheduling, the downloading hit rate of respective CDN nodes of different companies is improved, the back-to-source pulling probability is reduced, and for users, the downloading time delay of the users is reduced, so that the playing quality of streaming media files is further improved. The method comprises the following steps: acquiring an accumulated playing frequency of a streaming media file in a preset time period, and determining a popularity level of the streaming media file based on the accumulated playing frequency; determining a file scheduling mode according to the popularity level; and selecting a target node of the streaming media file according to the file scheduling mode, and obtaining the streaming media file through the target node.

Description

technical field [0001] The present application relates to the field of Internet technologies, and in particular, to an intelligent scheduling method, computer equipment and computer program product for streaming media files. Background technique [0002] CDN technology has been widely used in the current Internet field. CDN (Content Delivery Network, Content Delivery Network) is a distributed network established and covered on the bearer network and composed of edge node server groups distributed in different regions. In the face of the current large and frequent access demands of Internet users, the CDN network can use the global load balancing technology to redirect the user's access request to the nearest working edge node server, and the edge node server directly responds to the user's request. Request to achieve nearby access to resources. When the content that the user wants to access does not exist on the above-mentioned edge node server (ie CDN node) closest to the...

Problems solved by technology

[0003] Current streaming media software operators use CDN technology to provide services for users. Users can quickly download or upload streaming media files such as audio and video files (such as recording songs) through CDN technology. In practical applications, some audio and video playback software is due to user The scale is huge, and it is necessary to cooperate with multiple CDN service providers. These CDN nodes generally use random scheduling when providing services, and do not perform global coordinated scheduling according to the core indicators such as the characteristics, capacity, and cache hit rate of each CDN service provider, resulting in Some CDN nodes have a high utilization rate while others have a low utilization rate. For software operators, this situation cannot realize the full and effective use of network bandwidth resources, wastes a lot of bandwidth resources, and increases software operating costs. For users It is said that in many cases, it is still necessary to go back to the source to pull the target resources, which increases the user delay, causes the user to not be able to download and play the stream at the fastest speed, and reduces the playback quality
