Abstract

The invention provides a data caching method and device. A medium caching node for caching data is provided with a solid state disk and a mechanical hard disk, and medium data cached in the medium caching node is provided with a popular degree value. The method comprises the following steps that: preferentially caching the medium data with the high popular degree value in the solid state disk, and caching residual medium data in the mechanical hard disk; carrying out statistics on the access frequency of all medium data in the medium caching node according to a preset time period, and updating the popular degree value of the medium data according to the access frequency; and according to the updated popular degree value, regulating the medium data cached in the solid state disk and the mechanical hard disk. By use of the method, through the above means, the advantages of high reading performance of the solid state disk and low cost of the mechanical hard disk can be fully performed, and the integrity of user request data can be guaranteed on the basis of effectively improving system service performance.

Description

technical field [0001] The present application relates to the technical field of network systems, and in particular, to a data caching method and device. Background technique [0002] With the rapid development of the Internet and the popularity of smart TVs, network data traffic has doubled, causing network congestion and affecting business application experience. [0003] Taking Content Delivery Network (CDN) as an example, CDN, as a system that can improve the efficiency of Internet content transmission, can greatly improve the service quality and efficiency of video and other multimedia content transmission, and has been widely used. application. CDN is based on the network and edge servers deployed in various places. It uses the load balancing, content distribution, scheduling and other functional modules of the central platform to enable users to obtain the required content nearby, thereby reducing network congestion and improving the response speed and hit rate of us...
