For example, the overall VCDN resource on the node is sufficient, and the VCDN space of a certain provider is lacking. If the overall performance of the node is controlled, the demand of the provider cannot be guaranteed. It should be noted that the foregoing application scenario or the beneficial effect is only an example, and the embodiment of the present invention is not limited thereto. In a preferred embodiment of the present invention, the step of separately controlling the VCDN resources of different providers on the at least one node according to the VCDN resource capability information may include: responding to the content distribution request, according to different on the at least one node The VCDN space usage of the quotient determines the distribution node and will Content is distributed to the distribution node.

Through the above steps, the proxy server can be used to reduce the burden on the current execution subject. In a preferred embodiment of the present invention, separately controlling VCDN resources of different providers on at least one node may include at least one of: VCDN of different providers on at least one node according to VCDN resource capability information The VCDN bandwidth control is performed separately for the resources; the VCDN storage control is performed on the VCDN resources of different providers on the at least one node according to the VCDN resource capability information; and the VCDN resources of different providers on the at least one node are respectively performed according to the VCDN resource capability information.
