Abstract
A transmission path control device is connected to a management server and a router device located on the same area as the transmission path control device. The transmission path control device determines whether a corresponding router device has a port directed to an end area when receiving a virtual lease line (VLL) establishing request including a start area and the end area of the VLL. If not, the transmission path control device transmits the VLL establishing request to a default transmission path control device. If yes, the transmission path control device determines which router devices are transmission nodes constituting the VLL and determines which ports are ports to be connected. The transmission path control device further connect the ports used to connect one by one, thus to establish the VLL.
