Architecture Design Of CDN And Design And Implementation Of Configuration Management System

The thesis describes a general method of designing and implementing a content delivery network (CDN) system. Content distribution network system is mainly used for ICP(Internet content provider) provides the network acceleration service.The CDN load balance technology system includes two aspects, global server load balance is the control system as a whole. The local server load balance is on a node of the load balance scheduling. Through the global and local two load balancing server to optimize the allocation of resources and improve website service ability.Content distribution technology is the content of the update CDN control is an important technical means, include two main method. Squid is used to cache data, is a open source software, through the service on the one hand may provide Squid ICP network speed up service, on the other hand, we can effectively relieve the pressure of business server.Based on the above content distribution technology and content routing technology, puts forward a kind of typical CDN node of the network structure architecture:LVS+HAproxy+Squid+Apache/Nginx+Memcache+MySQL.The CDN configuration management system is a kind of management CDN configuration files of the system software, according to the software design, and realize the configuration management system function, and verified the system can according to the predetermined goal, highly efficient management the configuration files of the CDN system.
