A method for switching node main-standby controllers based on Content Delivery Network is disclosed by the present invention. The method includes the process that a node standby controller detects the state of the current node main controller, when the node main controller is abnormal, the node standby controller selects one node standby controller to replace as a new node main controller according to preset rules. A Content Delivery Network is also disclosed by the present invention. The present invention can avoid the problem that a manager changes the node main controller blindly, wherein the problem is caused by a network anomaly but not the malfunction of the node main controller, thus the performance of the manager is effectively improved and the bandwidth of the network is saved. |
