Disclosed are a proxy tunnel termination device with reduced complexity in setting a network, and a communication method for scalable network virtualization including the same. A communication system for scalable network virtualization according to an embodiment of the present invention comprises: a tunnel management unit for generating tunnels connected to tunnel termination parts of respective node parts including a first node part and a second node part, respectively; a VNID management unit for generating a virtual switching instance (VSI) for each virtual network identifier (VNID) set for respective virtual networks formed among the tunnel termination parts through the tunnels; a tunnel packet termination unit for receiving a packet from a first tunnel termination part of the first node part through the tunnel, and extracting VNID information to which the packet belongs from the received packet, to transmit the extracted VNID information to the VSI corresponding to the VNID; a VSI unit including a virtual port corresponding to a tunnel terminated at the tunnel packet termination unit, and performing an L2 switching on a terminated L2 packet transmitted from the tunnel packet termination unit to transmit the L2 packet to a destination virtual port; and a tunnel packet generation unit for transmitting the packet to a second tunnel termination part based on transmission destination information of the packet received through the VSI. |
