Abstract: Provided is a method for configuring a control tunnel and a direct tunnel in an IPv4 network-based IPv6 service providing system. To provide IPv6 service, when a random request terminal receives a tunnel response message from a control server by using service information downloaded from a portal server at the time of initialization, the request terminal configures a control tunnel with the control server, and is registered to the control server. The request terminal transmits and receives a direct tunnel request message and a direct tunnel response message with a counterpart terminal by using its terminal information learned during the control tunnel configuration, i.e., network position information and status information, thereby configuring a direct tunnel. Thus, IPv6 communication is made through IPv4 based IPv6 tunneling, so that IPv6 application services that are not yet widely used can easily come into wide use. Also, only software change of each terminal and a control server is required without changing existing network equipment, so that a cost burden of a service provider can be minimized.

Abstract: In a plurality of virtual tunnel routers including a first virtual tunnel router and a second virtual tunnel router, the first virtual tunnel router and the second virtual tunnel router request virtual network prefix information from a tunnel mapping controller. When the tunnel mapping controller generates virtual network prefix information of the first virtual tunnel router and the second virtual tunnel router, respectively, and transmits the same along with information of a list of adjacent virtual tunnel routers, the first virtual tunnel router and the second virtual tunnel router create a tunnel. With the tunnel established, the virtual network prefix information received by the first virtual tunnel router and second virtual tunnel router, respectively, is linked so that direct communication can be performed between the first virtual tunnel router and the second virtual tunnel router.

Abstract: A method for configuring a closed user network (CUN) using an IP tunneling mechanism and a CUN system are disclosed. In particular, disclosed is a technique of establishing a tunnel between a tunnel end edge device (TEED) and a control server by using an IP tunneling mechanism to allow terminals connected to the TEED to perform communications by using a closed IP, enabling the TEED to provide a network address translation (NAT) function so that the TEED can perform data forwarding like a general NAT, without performing tunneling on a destination IP outside the closed IP section, to perform communication, and allowing a terminal located in an area where the TEED is not provided to directly establish a tunnel with the control server by using a client software to thereby perform communications with a terminal or a server connected to the TEED by using the closed IP.
