Abstract

The invention discloses a cache-data query synchronization method for a CDN system. The cache-data query synchronization method includes the steps that characteristic information of files cached on CDN nodes is hashed multiple times to determine a first digit group; the to-be-set position in a first query array of a dispatching center is determined according to the first digit group, the determined to-be-set position is set, and a second query array is generated; characteristic information of a file in a source server is hashed multiple times to determine a second digit group; whether the position corresponding to the second digit group in the second query array is set or not is queried, and whether some file is cached on the CDN node or not is determined according to the query result. The invention further provides a cache-data query synchronization system for the CDN system. By means of the cache-data query synchronization method and system for the CDN system, the information amount of synchronization uploading of edge nodes is decreased, and the data querying speed of the dispatching center is increased.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a cache data query synchronization method and system for a CDN system. Background technique [0002] The full name of CDN is Content Delivery Network, that is, content distribution network. Its purpose is to publish the content of the website to the "edge" of the network closest to the user by adding a new layer of network architecture to the existing Internet, so that users can obtain the required content nearby, solve Internet network congestion, and improve The responsiveness of the user's access to the website. [0003] CDN technology is divided into two technologies: dynamic acceleration and static acceleration. At present, static acceleration is commonly used, that is, CDN nodes are deployed at the edge of the network. When a user requests a certain service, the CDN system dispatches, that is, global load balancing ( The Global Server Load Balance (GSLB) strategy dir...
