<p>PURPOSE: A cloud network device and a method thereof are provided to improve cloud service environment and remote working environment by providing a layer 2-based virtual private network (VPN) with high security and stability to moving users. CONSTITUTION: A communication node (310) comprises an authenticating part (311), a virtual switch instance (VSI) setting part (313), a path searching part (315), a path mapping part (317), and a dynamic path mapping table (319). The path searching part searches the dynamic path mapping table to check whether or not a VSI corresponding to packet information exists when receiving a packet from a user terminal. If the VSI corresponding to the packet information does not exist, the authenticating part authenticates a user as a cloud network control device. The VSI setting part is connected to a network after setting the VSI based on VSI information on the authenticated user receiving from the cloud network control device. The path mapping part stores the set VSI in the dynamic path mapping table by mapping the set VSI to the packet information.
