The invention discloses a CDN node detection and resource scheduling system and method in an education network. The system comprises a URL collection subsystem used for collecting a domain name address accessed by a client in the education network and stores the collected domain name address in a domain name library; a preprocessing server used for reading the domain name address from the domain name library and inserting the domain name address in a domain name queue; a CDN node detection system used for reading the domain name address from the domain name queue, detecting a CDN acceleration node, and when the domain name address is detected to be accelerated by the CDN acceleration node, storing the domain name address and an IP address of the corresponding CDN acceleration node in a CDN node library of the education network; and a data processing server used for scheduling an optimal CDN acceleration phase for a client according to the request of the client, so as to accomplish the resource scheduling of the CDN node library and realize a CDN node detection and quality of service monitoring resource scheduling method in a large ISP network.
