The present disclosure describes a method for diverting a live video stream, a CCL server, and a system thereof, and relates to the field of data transmission technology. The method includes: a target stream-pushing edge node receives and maintains a target live video stream pushed by an anchor terminal, and reports video stream information of the target live video stream to the CCL server through a locally deployed CCL proxy; when a stream-pulling request of the target live video stream sent by a target static parent node is received, a dynamic parent node M determines whether the target live video stream is maintained locally; if the target live video stream is not maintained locally, the dynamic parent node M determines the target stream-pushing edge node from the CCL server through a locally deployed CCL proxy; and the dynamic parent node M pulls the target live video stream from the target stream-pushing edge node and feeds back the target live video stream to the target static parent node. The present disclosure may save the data transmission resource in a CDN cluster.
