USER-CENTRIC VIRTUAL NETWORK AND BUILDING METHOD THEREOF

摘要

PURPOSE: A user-centric virtual network and a method for building thereof are provided to let a tunnel termination and address translation device or a terminal client perform tunneling with a tunnel relay device and connect virtual IP routing information between the devices to a corresponding tunnel. CONSTITUTION: Each of tunnel termination and address translators (420,430) is connected to a private network. A tunnel relay device (410) transmits data through a first tunneling with one of the tunnel termination and address translators. A terminal client (300) transmits data through a second tunneling with the other of the tunnel termination and address translators. A virtual IP is allocated to each of the tunnel termination and address translators, the terminal client, and the tunnel relay device. Each of the first tunneling and the second tunneling connects virtual IP routing information to a corresponding tunnel.
