Control method, control device, and processor in software defined network

A control method in a software defined network (SDN)-based computerized content distribution system comprising:

• receiving, by a first control device in the SDN-based computerized content distribution system, a service request, wherein the first control device comprises:
• a non-transitory memory configured to store an operating system;
• and
• a processor configured to execute the operating system stored in the non-transitory memory;
• obtaining, by the first control device, location information of a requested network device for processing a service from a shared device, wherein the requested network device is registered in a second control device in the SDN-based computerized content distribution system, wherein the shared device stores location information of each network device in the SDN-based computerized content distribution system, wherein the location information stored in the shared device is registered by a controlling control device of the network device, and wherein the location information of the requested network device comprises a device identity (ID) of the second control device where the requested network device is registered, an Internet Protocol (IP) address of the second control device where the requested network device is registered, and a device ID of the requested network device;
• establishing, by the first control device, a remote object proxy of the requested network device in the first control device according to the location information of the requested network device;
• and
• controlling, by the first control device, the requested network device using the remote object proxy established in the first control device.
