The invention provides a streaming media caching method and device and a computer readable storage medium, and relates to the technical field of multimedia. The streaming media caching method comprises the following steps: determining streaming media popularity of a target streaming media by utilizing the probability that a user operates the target streaming media; determining association degree between the target streaming media and other streaming media by using the probability that the user operates the other streaming media and the probability that the user continuously operates the targetstreaming media and the other streaming media; determining comprehensive popularity of the target streaming media by utilizing the streaming media popularity of the target streaming media and the association degree between the target streaming media and the other streaming media; and caching the target streaming media according to the comprehensive popularity of the target streaming media. According to the invention, the comprehensive popularity of the target streaming media can be predicted more accurately, and the target streaming media are cached according to the comprehensive popularity of the target streaming media, so that the CDN cache hit rate is improved.
Description
technical field [0001] The present disclosure relates to the field of multimedia technology, and in particular to a streaming media caching method, device and computer-readable storage medium. Background technique [0002] When users use CDN (Content Delivery Network, Content Delivery Network) to accelerate streaming media, the CDN needs to provide high-performance, low-latency acceleration services. [0003] The CDN cache hit rate refers to the probability of hitting the cache when a user accesses streaming media. The edge streaming media cache node is the part closest to the user in the entire CDN. Whether the streaming media cached by it is frequently accessed by users (the cache hit rate) will directly affect the overall performance of the CDN. When the CDN cache hit rate is low, the CDN has problems such as high return-to-origin rate, poor performance, and poor user experience. Contents of the invention [0004] A technical problem to be solved by the present disclo...
