And step S60, the server sends the user operation data to a corresponding designated network element through a virtual input device.
Specifically, the server sends the key data input by the keyboard, the data moved and clicked by the mouse to the corresponding designated network element through the virtual input device (for example, the server sends the user operation data transmitted by the PC to the network element n through the virtual input device n), and by sending the user operation data to the designated network element, the system operation state of the designated network element can be intervened, controlled and managed by the user.
In the invention, the system software of the server can simulate virtual display equipment and virtual input equipment to be used by each network element, the operating system of the network element is communicated with the virtual display equipment and the virtual input equipment through a virtual equipment driver, the virtual display equipment and the virtual input equipment are used by the operating system of the network element without essential difference from real equipment, the virtual display equipment is used by the operating system of the network element to carry out system desktop display, and the virtual input equipment is used to obtain input user operation data.
