Abstract:
1. A method of establishing a user centric virtual network, the method comprising: performing a first tunneling operation between a first tunnel end and an address translation device, which are connected to a first private network, and a tunnel relay device; performing a second tunneling operation between a second tunnel end and an address translation device, which are connected to a second private network, and the tunnel relay device; and performing a third tunneling operation between the tunnel relay device and an end client, wherein a virtual IP is allocated differently for each user, to each of the first and second tunnel ends, the address translation devices, the end client, and the tunnel relay device; and each of the first to third tunneling operations connects routing information on the virtual IP to a corresponding tunnel; wherein each network address translator between the first tunnel end and address translation device and the tunnel relay device, between the second tunnel end and address translation and the tunnel relay device, and between the tunnel relay device and the end client.
