CDN scheduling system, method and device

The invention discloses a CDN (Content Delivery Network) scheduling system, method and device, which are used for solving the problems that in the existing CDN scheduling method, user-side hardware isshared and used, user-side interference is easily introduced, the risk of misjudgment on the CDN node service capability is caused, software needs to be deployed on the user side, and the expenditurecost is increased. The system comprises: a CDN node used for periodically reporting system reference data and service reference data of the CDN node to a data analysis platform; a data analysis platform which is used for calculating a service capability value of each CDN node by utilizing a preset algorithm according to the system reference data and the service reference data reported by the CDNnode; and a scheduling server which is used for receiving the data request sent by the terminal and scheduling the data request to the specified CDN node according to the acquired service capability value of each CDN node. 本发明公
