Abstract
A virtual interface having a global address of a physical interface on an Internet side of a gateway is provided in a terminal. An application unit of the terminal transmits a packet to the Internet using the virtual interface. The packet is transferred to the gateway through a downlink transfer path. The gateway transmits the packet from the physical interface on the Internet side to the Internet.
Claims15
A network system comprising:
- a gateway device arranged on a border between a public network and a private network, and configured to relay data communicated therebetween;
- a terminal located in the private network, including a virtual interface that corresponds to a physical interface of the gateway on a public network side, and configured to transmit and receive data to and from other terminals located on the public network through the virtual interface;
- and
- a transfer path configured to transfer data between the physical interface and the virtual interface.
A terminal comprising a virtual interface configured to correspond to a physical interface of a gateway on a public network side, the gateway arranged on a border between a public network and a private network and configured to relay data communicated therebetween, wherein
- the terminal is configured to transmit and receive data to and from other terminals located on the public network through the virtual interface using a global address assigned to the physical interface.
A gateway used in a network system that includes a gateway device that is arranged on a border between a public network and a private network, and that relays data communicated therebetween, a terminal that is located in the private network, that includes a virtual interface corresponding to a physical interface of the gateway on a public network side, and that transmits and receives data to and from other terminals located on the public network through the virtual interface using a global address assigned to the physical interface;
- the gateway comprising:
- a path setting unit configured to set an uplink transfer path for transferring data to a terminal located in the private network;
- a data transferring unit configured to transfer data received from a terminal on the public network, to the terminal in the private network through the uplink transfer path;
- and
- a data receiving unit configured to receive data transferred from the terminal in the private network and to transmit the data to the public network.
