Abstract

Provided is a communication method of a hub that selects a transmission route from the hub to a receiving terminal of a receiving virtual group based on interface information about at least one interface which is available for use by the receiving terminal and is received from the receiving terminal and interface information about at least one interface which is available for use by a transmitting terminal of a transmitting virtual group and is received from the transmitting terminal.

Claims

1. A communication method of a hub, the method comprising:

receiving, from at least one receiving terminal of a receiving virtual group, a data request message including interface information about at least one interface available for use by the at least one receiving terminal;

receiving, from at least one transmitting terminal of a transmitting virtual group and including data corresponding to the data request message, a data transmission message including interface information about at least one interface available for use by the at least one transmitting terminal;

selecting a transmission route from a hub of the transmitting virtual group to the at least one receiving terminal based on the interface information of the at least one receiving terminal and the interface information of the at least one transmitting terminal; and

transmitting the data transmission message via the selected transmission route.

2. The method of claim 1, further comprising:

collecting interface information from the at least one transmitting terminal of the transmitting virtual group.

3. The method of claim 2, wherein the collecting includes collecting interface information of the at least one transmitting terminal in response to the at least one transmitting terminal being first registered in the transmitting virtual group.

4. The method of claim 1, wherein interface information of the at least one receiving terminal and/or the at least one transmitting terminal includes information about the transmission route and a reception route used by the respective terminals, a link capacity of at least one interface available for use by the respective terminals, a bandwidth of the respective terminals, an interface type available for use by the respective terminals, a physical characteristic, or any combination thereof.

5. The method of claim 1, wherein the selecting includes selecting the transmission route based on a measurement result with respect to a Round Trip Time (RTT) transmission rate of the transmission route.

6. The method of claim 1, further comprising:

deleting or changing information about a reception route from the at least one receiving terminal to the hub of the transmitting virtual group, the information being previously stored in the hub of the transmitting virtual group, in response to the data request message being received.

13. A non-transitory computer-readable medium comprising a program for instructing a computer to perform the method of claim 1.

7. A communication method of a receiving terminal of a receiving virtual group, the method comprising:

transmitting a data request message including interface information about at least one interface available for use by the receiving terminal to request data of a transmitting terminal of a transmitting virtual group;

receiving, from the transmitting virtual group, a data transmission message including interface information about the at least one interface available for use by the transmitting terminal; and

updating a mapping table using the interface information of the receiving terminal and the interface information of the transmitting terminal, so that the mapping table indicates that the interface information of the receiving terminal and the interface information of the transmitting terminal are mapped to each other.

8. The method of claim 7, further comprising:

receiving data corresponding to the data request message via a transmission route selected by a hub of the transmitting virtual group,

wherein the hub selects one route from a plurality of routes as the transmission route based on the interface information of the receiving terminal and the interface information of the transmitting terminal.

9. The method of claim 7, wherein the updating comprises changing or deleting information stored in the mapping table based on the interface information of the receiving to terminal and the interface information of the transmitting terminal.

10. The method of claim 7, wherein interface information of the receiving terminal and/or the transmitting terminal includes information about a transmission route and a reception route used by the respective terminals, a link capacity of at least one interface available for use by the respective terminals, a bandwidth of the respective terminals, an interface type available for use by the respective terminals, a physical characteristic, or any combination thereof.

11. A communication method of a transmitting terminal of a transmitting virtual group, the method comprising:

receiving, from a hub of the transmitting virtual group, a data request message including interface information about at least one interface available for use by a receiving terminal of a receiving virtual group;

transmitting a data transmission message including interface information about at least one interface available for use by the transmitting terminal to transmit data corresponding to the data request message; and

updating a mapping table using the interface information of the receiving terminal and the interface information of the transmitting terminal, so that the mapping table indicates that the interface information of the receiving terminal and the interface information of the transmitting terminal are mapped to each other.

12. The method of claim 11, wherein:

the transmitting includes transmitting the data transmission message to the receiving terminal via a transmission route selected by the hub, and

the hub determines one route from a plurality of routes as the selected route based on the interface information of the receiving terminal and the interface information of the transmitting terminal.

14. A communication method of a hub, the method comprising:

selecting a transmission route from a hub of a transmitting virtual group to a receiving terminal according to interface information of the receiving terminal and interface information of a transmitting terminal; and

transmitting a data transmission message via the selected transmission route.

15. The method of claim 14, wherein the interface information of the receiving terminal and the transmitting terminal are previously stored in the hub of the transmitting virtual group.

16. The method of claim 14, wherein the interface information of the receiving terminal is transmitted to the hub of the transmitting virtual group along with a data request from the receiving terminal.

17. The method of claim 14, wherein the interface information of the transmitting terminal is transmitted to the hub of the transmitting virtual group in response to receiving a data request from the receiving terminal.
