Abstract

Disclosed are an ID based communication system and a method for controlling data transport therein. A method according to an exemplary embodiment of the present invention includes: by a data receiving apparatus, generating and transporting an information request message for requesting data information of contents corresponding to a content ID; receiving a response message including the data information regarding the contents corresponding to the content ID from any one data providing apparatus; deciding one or more requested data among the data corresponding to the contents and generating and transporting a data request message for requesting transportation of the requested data to the data providing apparatus; and receiving the detected data from the data providing apparatus, wherein the data providing apparatus detects one or more requested data verified from the data request message among the data corresponding to the contents.

Claims

1. A method for controlling data transport in an ID based communication system, the method comprising:

generating and transporting, by a data receiving apparatus, an information request message for requesting data information of contents corresponding to a content ID;

receiving, by a data receiving apparatus, a response message including the data information regarding the contents corresponding to the content ID from any one data providing apparatus providing the contents requested by the data receiving apparatus;

deciding, by a data receiving apparatus, one or more requested data among the data corresponding to the contents based on the data information included in the received response message and generating and transporting a data request message for requesting transportation of the requested data to the data providing apparatus; and

receiving, by a data receiving apparatus, the detected data from the data providing apparatus, wherein the data providing apparatus detects one or more requested data verified from the data request message among the data corresponding to the contents.

2. The method of claim 1, wherein the response message includes a total data size of the contents and a unit transport size of the contents, and selectively includes data sending rate of the data providing apparatus.

3. The method of claim 2, further comprising:

determining, by a data receiving apparatus, the total number of data corresponding to the contents based on the total data size of the contents and the unit transport size of the contents included in the response message.

4. The method of claim 2, wherein in the generating and transporting of the data request message, some or all of the data corresponding to the contents are decided as the requested data according to specifications such as the data sending rate of the data providing apparatus, the total data size of the contents, the unit transport size of the contents, data receiving rate of the data receiving apparatus, and a buffer size.

5. The method of claim 1, wherein the data request message includes start information and end information for one or more request data among the data corresponding to the contents.

6. The method of claim 5, wherein in the receiving of the detected data, requested data corresponding to a start sequence among the detected requested data is first sequentially received based on the start information and the end information of the requested data included in the data request message.

7. The method of claim 1, wherein in the receiving of the detected data, a response message including sequence information of the detected data and payload data is received.

8. The method of claim 1, wherein the information request message includes the content ID and data receiving rate of the data receiving apparatus.

9. The method of claim 8, further comprising:

adjusting the data sending rate of the data providing apparatus based on the data receiving rate of the data receiving apparatus included in the information request message.

10. The method of claim 9, further comprising:

setting a data sending speed of the data providing apparatus based on the adjusted data sending rate.

11. The method of claim 1, further comprising:

transporting, when unreceived data is present among the requested data, a data re-request message for requesting transportation of the unreceived data to the data providing apparatus.

12. The method of claim 11, wherein the transporting of the data re-request message includes generating a sequence list based on sequence information regarding the unreceived data, and

when transportation of the data from the data providing apparatus is completed, retransportation of the data corresponding to the sequence list is requested.

13. The method of claim 11, further comprising:

retransporting requested data corresponding to a sequence for the unreceived data to the data receiving apparatus from the data providing apparatus based on the data re-request message including the sequence information regarding the unreceived data among the requested data.

14. The method of claim 1, further comprising:

after the generating and transporting of the information request message, setting, by the ID based communication network apparatus, a path between the data receiving apparatus and the corresponding data providing apparatus by determining the position of the data providing apparatus that is to transfer the information request message based on the content ID included in the information request message.

15. An ID based communication system comprising:

multiple data providing apparatuses managing data corresponding to one or more contents and information of the data and providing requested data and the information of the data; and

a data receiving apparatus transporting an information request message for requesting data information of contents corresponding to a content ID to the data providing apparatus, and verifying the data information regarding the contents from a response message received in response to the information request message to request decided requested data among data corresponding to the contents to any one data providing apparatus providing the contents requested by the data receiving apparatus,

wherein the data receiving apparatus determines the total number of the data corresponding to the contents based on a total data size of the contents and a unit transport size of the contents included in the response message and decides some or all of the data corresponding to the contents as the requested data according to specifications such as data sending rate of the data providing apparatus, the total data size of the contents, the unit transport size of the contents, data receiving rate of the data receiving apparatus, and a buffer size.

16. The system of claim 15, wherein any one data providing apparatus verifies and detects start information and end information regarding the requested data from the data receiving apparatus and first sequentially transports requested data corresponding to a start sequence among the detected data.

17. The system of claim 15, wherein any one data receiving apparatus, when unreceived data is present among the requested data, generates a sequence list based on sequence information regarding the unreceived data and when transportation of the data from the data providing apparatus is completed, requests retransportation of data corresponding to the sequence list to the data providing apparatus.

18. The system of claim 15, wherein any one data providing apparatus retransports requested data corresponding to the sequence for the unreceived data to the data receiving apparatus when receiving the sequence information regarding the unreceived data among the requested data from the data receiving apparatus.

19. The system of claim 15, further comprising:

an ID based communication network apparatus determining the position of the data providing apparatus that is to transfer the information request message based on the content ID included in the information request message between the data receiving apparatus and the multiple data providing apparatuses to set a path between the data receiving apparatus and the corresponding data providing apparatus and transfer data.
