Tunneling service method and system
First Claim
1. A tunneling service method of a client node in a network to which the client node, at least one dynamic host configuration protocol (DHCP) server, and a tunnel router are connected, the method comprising:
- transmitting an information request message, which requests information required for connection to the network, to the at least one DHCP server selected by the client node;
receiving an acknowledgement message, which contains an address of the tunnel router, from the DHCP server selected by the client node; and
the client node detecting the address of the tunnel router contained in the acknowledgement message and generating a packet for a tunneling service using the detected address of the tunnel router.

Abstract
A tunneling service method and system enabling data communication between different networks, in which an address of a tunneling service server used in a client node can be easily designated, the tunneling service method includes: transmitting an information request message, which requests information required for connection to the network, to a dynamic host configuration protocol (DHCP) server selected by the client node; receiving an acknowledgement message, which contains an address of the tunnel router, from the DHCP server selected by the client node; and the client node detecting the address of the tunnel router contained in the acknowledgement message and generating a packet for a tunneling service using the detected address of the tunnel router.

5. A tunneling service method of a client node in a network to which the client node, a plurality of dynamic host configuration protocol (DHCP) servers, and a plurality of tunnel routers are connected, the method comprising:
-
transmitting an information request message, which requests information required for connection to the network, to at least one DHCP server selected by the client node;
receiving an acknowledgement message, which contains addresses of the plurality of tunnel routers, from the at least one DHCP server selected by the client node; and
the client node detecting and storing the addresses of the plurality of tunnel routers contained in the acknowledgement message, selecting an address of one of the tunnel routers, and generating a packet for a tunneling service using the address of the selected tunnel router. - View Dependent Claims (6, 7)

8. A client node connected to a dynamic host configuration protocol (DHCP) server and using a tunneling service, the client node comprising:
-
a message transmitting and receiving unit transmitting and receiving a DHCP message from the DHCP server;
a storing unit storing address information of a tunnel router;
a control unit detecting an address of the tunnel router contained in a message received from the DHCP server via the message transmitting and receiving unit, storing the detected address of the tunnel router in the storing unit, and generating a packet for the tunneling service; and
a packet generating unit generating the packet for the tunneling service under control of the control unit. - View Dependent Claims (9, 10, 11, 12)

13. A dynamic host configuration protocol (DHCP) server supporting a tunneling service for a client node in a network, the DHCP server comprising:
-
a storing unit storing address information of at least one tunnel router connected to the network;
a message transmitting and receiving unit transmitting and receiving a DHCP message with the client node; and
a control unit generating an option field containing the address information of the at least one tunnel router stored in the storing unit when an information request message, which requests information required for connection to the network, is received from the message transmitting and receiving unit, and transmitting the DHCP message including the option field to the message transmitting and receiving unit. - View Dependent Claims (14, 15)

16. A tunneling service method of a client node in a network, the method comprising:
-
transmitting an information request message requesting information for connecting to the network;
receiving an acknowledgement message containing an address of a tunnel router for connecting to the network; and
detecting the address of the tunnel router contained in the acknowledgement message and generating a packet for a tunneling service using the detected address of the tunnel router. - View Dependent Claims (17, 18, 19, 20)
