The cloud server scheduling system according to claim 6, wherein in the case of transmitting large content belonging to a small virtual device and transmitting large content by a large virtual device, after each time of timing selection of a transmission node by the virtual device, the server side notifies the virtual device of the next shortest time interval of selecting the transmission node at a timing, evaluates the transmission speed of the transmission node after the shortest time interval passes, switches the node with the highest real-time transmission speed to perform data transmission if the transmission speed is lower than a switching limit value, and transmits data information to the target virtual device, and the data transmission is ended.
10. The cloud server scheduling system of claim 6, wherein when a client abnormally initiates a plurality of connection requests, the virtual device rejects its connection requests.
