Abstract

Provided is a system for sharing data using a network. When a data transmission apparatus included in the data sharing system generates data, the data transmission apparatus may transmit a data generation message to a data reception apparatus. The data reception apparatus may receive the data based on the data generation message.

Claims

1. A data transmission apparatus, comprising:

a transmitter configured to transmit, to a data reception apparatus, a data generation message comprising information associated with transmission data; and

a receiver configured to receive a data request message from the data reception apparatus in response to the data generation message,

wherein, in response to the data request message, the transmitter is further configured to transmit the transmission data to the data reception apparatus.

2. The data transmission apparatus of claim 1, wherein information associated with the transmission data comprises at least one of:

a name of the transmission data, a creator of the transmission data, a generated time of the transmission data, a format of the transmission data, and a capacity of the transmission data.

3. The data transmission apparatus of claim 1, further comprising:

a data divider configured to divide the transmission data into a plurality of segments,

wherein the transmitter is further configured to transmit each of the segments to the data reception apparatus.

4. The data transmission apparatus of claim 1, wherein the receiver is further configured to receive, from the data reception apparatus, a reception confirmation message with respect to the data generation message.

5. The data transmission apparatus of claim 1, wherein:

the transmitter is further configured to generate the data generation message via a data transmission hub configured to maintain state information associated with the data reception apparatus; and

the receiver is further configured to receive the data request message via the data transmission hub.

6. The data transmission apparatus of claim 1, wherein:

the data reception apparatus comprises a primary data reception apparatus and a secondary data reception apparatus;

the receiver is further configured to receive the data request message from the primary data reception apparatus and the secondary data reception apparatus;

the secondary data reception apparatus is configured to receive the data request message from the primary data reception apparatus;

the transmitter is further configured to transmit the transmission data to the secondary data reception apparatus; and

the secondary data reception apparatus is further configured to transmit the transmission data to the primary data reception apparatus.

7. A data reception apparatus, comprising:

a receiver configured to receive, from a data transmission apparatus, a data generation message comprising information associated with transmission data; and

a transmitter configured to transmit a data request message to the data transmission apparatus in response to the data generation message,

wherein, in response to the data request message, the receiver is further configured to receive the transmission data from the data transmission apparatus.

8. The data reception apparatus of claim 7, wherein information associated with the transmission data comprises at least one of:

a name of the transmission data, a creator of the transmission data, a generated time of the transmission data, a format of the transmission data, and a capacity of the transmission data.

9. The data reception apparatus of claim 7, wherein the transmitter is further configured to transmit, to the data transmission apparatus, a reception confirmation message with respect to the data generation message.

10. The data reception apparatus of claim 7, wherein:

the transmitter is further configured to transmit the data request message to a second data reception apparatus configured to receive the transmission data from the data transmission apparatus; and

in response to the data request message, the receiver is further configured to receive the transmission data from the second data reception apparatus.

11. The data reception apparatus of claim 7, wherein:

the receiver is further configured to receive the data generation message via a data transmission hub configured to maintain state information associated with the data reception apparatus; and

the transmitter is further configured to transmit the data request message via the data transmission hub.

12. A data transmission hub, comprising:

a table generator configured to generate an association table containing state information associated with a data reception apparatus connected to the data transmission hub;

a receiver configured to generate a data generation message from a data transmission apparatus; and

a transmitter configured to forward the data generation message to the data reception apparatus based on the association table.

13. The data transmission hub of claim 12, wherein:

in response to the data generation message, the receiver is further configured to receive a data request message from the data reception apparatus; and

the transmitter is further configured to forward the data request message to the data transmission apparatus.

14. The data transmission hub of claim 13, wherein:

in response to the data request message, the receiver is further configured to receive transmission data from the data transmission apparatus, and

the transmitter is further configured to forward the transmission data to the data reception apparatus.

15. The data transmission hub of claim 12, wherein the state information corresponds to information regarding whether the data reception apparatus is ready to receive the transmission data.

16. A data transmission hub, comprising:

a receiver configured to generate a data generation message from a data transmission apparatus; and

a transmitter configured to forward the data generation message to a data reception apparatus based on state information associated with the data reception apparatus.

17. A data transmission method, comprising:

transmitting, to a data reception apparatus, a data generation message containing information associated with transmission data;

receiving a data request message from the data reception apparatus in response to the data generation message; and

in response to the data request message, transmitting the transmission data to the data reception apparatus.

18. A data reception method, comprising:

receiving, from a data transmission apparatus, a data generation message containing information associated with transmission data;

transmitting a data request message to the data transmission apparatus in response to the data generation message; and

in response to the data request message, receiving the transmission data from the data transmission apparatus.

19. A data transmission method, comprising:

generating an association table containing state information associated with a data reception apparatus connected to a data transmission hub;

generating a data generation message from a data transmission apparatus; and

forwarding the data generation message to the data reception apparatus, based on the association table.

20. A data transmission method, comprising:

generating a data generation message from a data transmission apparatus; and

forwarding the data generation message to a data reception apparatus based on state information associated with the data reception apparatus.
