摘要： Technology for forming a virtual private network (VPN) is provided. A VPN gateway that supports mobility with a connection node having a virtual home address (HoA) and a care of address (CoA) includes a mobility support unit, a data security unit, and a virtual address converter. When a packet is transferred from the connection node, the mobility support unit sustains a binding relationship between a home address (HoA) of the connection node and the changed CoA, and processes a mobility tunnel for the packet, thereby generating a first conversion packet. The data security unit performs a security test of the first conversion packet. The virtual address converter converts the HoA of the connection node, which is a source address of the first conversion packet in which the security test is complete, to a private network internal address that can be used in the VPN, thereby generating a second conversion packet.

摘要： The present invention relates to tunneling an IPv6 packet through an IPIv4 network. In using a tunneling method upon transmitting an IPv6 packet in an IP network, when destination nodes desired to be communicated are located within the same IPv6 prefix network, IPv6 prefix information is added for the management of a tunnel entry. Hence, tunneling information on terminals located within the same IPv6 prefix network can be managed as one tunnel entry. Accordingly, the time consumed when retrieving a tunnel entry can be reduced.

摘要： 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.

摘要： In order for a peer node to perform direct communication with a correspondent peer node in an Internet protocol network, the peer node receives a virtual address of the correspondent peer node from a server, and then when the peer node can directly set a tunnel with the correspondent peer node, the peer node sets a tunnel with the correspondent peer node, and when the peer node cannot directly set a tunnel with the correspondent peer node, the peer node sets a tunnel with a tunnel repeater. Thereafter, the peer node connects a virtual address of the correspondent peer node as route information to the tunnel. Thereby, a packet using a virtual address of the correspondent peer node as a destination is transmitted to the correspondent peer node through a predetermined tunnel.
