Docker technology based CDN dynamic content acceleration method and system

Abstract

The invention discloses a Docker technology based CDN dynamic content acceleration method and system, and relates to the technical field of computer application. The method comprises that a website DNS server delivers an analytical right, to analyze a host name of a URL corresponding to user request content, to a special DNS server of the CDN, and the special DNS server of the CDN returns the IP address of a CDN edge computing server to a user; the user requests the CDN edge computing server for a resource to which a target URL is directed; if the resource includes dynamic content, a Docker warehouse is asked for a Docker mirror image including a resource program and database, the Docker mirror image is downloaded, a Docker container is started, the program in the mirror image is executed, and the dynamic content corresponding to the program is generated and back fed to the user; and if the resource does not include dynamic content, static content query is implemented, and a query result is back fed to the user. Thus, response time of accessing Internet dynamic content is reduced, the total network flow is reduced, and the computing resource utilization rate of CDN nodes is improved.

Description

technical field [0001] The present invention relates to the technical field of computer applications, in particular to a method and system for accelerating CDN dynamic content based on Docker technology. Background technique [0002] With the rapid development of the Internet and the rapid increase of Internet content, network bandwidth and delay are the key factors that affect the user experience of Internet applications. Network bandwidth can gradually increase with the construction of network infrastructure. However, due to physical limitations such as signal propagation delay and processing delay caused by routers and switches, the delay cannot be reduced infinitely, and the delay will directly affect users. sense of experience. At present, the CDN system (Content Delivery Network, content distribution network) can better alleviate the delay problem, but still has its limitations. [0003] The CDN system refers to the geographically distributed deployment of multiple p...

Problems solved by technology

[0004] However, the existing CDN system can only cache static content (static content refers to the files that actually exist in the server, such as pictures, videos, Javascript script files, etc.), and cannot cache dynamic content (dynamic content refers to dynamically generated files for each request). content, such as various interface calls) for caching

In addition, the traditional physical CDN nodes only play the role of content caching, and the CPU, memory and other computing resources of the physical CDN nodes are largely idle, and the hardware resource utilization rate is low.
