Abstract:
1. A method for switching a node main-standby controller based on a content distribution network (CDN), comprising: A, all node standby controllers detecting status of a current node main controller; B, the all node standby controllers, detecting other node standby controllers respectively and exchange and store performance parameters mutually; C, when the current node main controller is abnormal, a node standby controller from along the all node standby controllers which firstly detects that the current node main controller is abnormal selecting one node standby controller to be a new node main controller by replacement according to a preset rule and sending a switching request to notify the selected node standby controller; and D, the selected node standby controller being switched to be the new node main controller based on the switching request, notifying a switching result to other standby controllers and reporting to a manager; wherein, the preset rule comprises a rule of selecting the one node standby controller with a normal status and an optimal performance according to the stored status and the performance parameters of the node standby controller.
