Abstract

The invention discloses a CDN quality evaluation system comprising: a data collection subsystem used for collecting a business index when a terminal user accesses CDN by passive monitoring or active dialing test; a data application subsystem used for scoring the CDN quality of each node according to the collected index to obtain an intuitive quality score; meanwhile in combination with geographic information, the CDN business range is divided, poor quality nodes and high quality nodes are analyzed through the obtained quality score, quality early warning is executed according to analysis result, and visible comprehensive display of the quality of the nodes is realized. The CDN quality evaluation system provided by the invention provides reference of the quality monitoring and optimization of CDN nodes by evaluating the quality of the nodes, intuitively displaying the quality conditions of the nodes, analyzing the quality of the nodes and the regions and globally displaying the quality of the entire CDN business.

Description

technical field [0001] The invention relates to a CDN quality evaluation system. Background technique [0002] Content distribution network (CDN) is a new type of network content service system, which is built on the basis of IP network, and provides content distribution and service based on the efficiency requirements, quality requirements and content order of content access and application; and from a broad perspective, CDN represents a high-quality, high-efficiency, network application service model with a clear network order built on the basis of the network. [0003] Simply put, the content distribution network (CDN) is a strategically deployed overall system, including distributed storage, load balancing, network request redirection and content management four elements, while content management and global network traffic management ( Traffic Management) is the core of CDN. Through the judgment of user proximity and server load, CDN ensures that content can serve user...
