Abstract

Provided is an apparatus and method for controlling a network using identification information of an object. The network controlling apparatus may include an extractor to extract identification information of a receiving object from received data, and a controller to verify, from a database, forwarding information that is stored in correspondence to the identification information, and to transfer the data to a gateway associated with a second domain designated by the forwarding information, when the receiving object is not included in a first domain.

Claims

1. An apparatus for controlling a network using identification information of an object, the apparatus comprising:

an extractor to extract identification information of a receiving object from received data; and

a controller to verify, from a database, forwarding information that is stored in correspondence to the identification information, and to transfer the data to a gateway associated with a second domain designated by the forwarding information, when the receiving object is not included in a first domain.

2. The apparatus of claim 1, wherein when the extracted identification information is not retrieved from the database, the controller verifies that the receiving object is not included in the first domain.

3. The apparatus of claim 1, wherein the database comprises, as the forwarding information, at least one of a routing hint including domain identification information of from a top level domain to a domain to which the receiving object is registered, domain identification information associated with the second domain, and an address of the gateway connected to the second domain.

4. The apparatus of claim 1, wherein when the forwarding information is not verified from the database, the controller extracts a routing hint corresponding to identification information of the receiving object from the data, transmits a route search request to a gateway associated with at least one route domain included in the extracted routing hint, and determines, as the second domain, a route domain that transmits a response to the route search request and thereby transfers the data to the gateway associated with the second domain.

5. The apparatus of claim 4, wherein:

a domain grade is assigned to each of the at least one route domain included in the routing hint, and

the controller transmits the route search request to a gateway associated with a route domain having a relatively lower domain grade.

6. The apparatus of claim 1, wherein when the forwarding information is not verified from the database and a routing hint corresponding to identification information of the receiving object is not extracted from the data, the controller transmits a lookup information request to a route domain having a relatively upper domain grade with respect to the first domain, and receives forwarding information corresponding to identification information of the receiving object from a gateway associated with the route domain that receives the lookup information request.

7. The apparatus of claim 6, wherein when there is no route domain having the relatively upper domain grade with respect to the first domain, the controller transmits the lookup information request to a gateway associated with a route domain having an equivalent or relatively lower domain grade with respect to the first domain.

8. The apparatus of claim 1, wherein when the receiving object is included in the first domain, the controller transmits the data to the receiving object.

15. The apparatus of claim 1, wherein network controlling apparatus can use for information forwarding with the help of object identification information in a hierarchical topology.

16. The apparatus of claim 1, wherein network controlling apparatus can maintain a forwarder information database with the help of object identification information in a hierarchical topology.

17. The apparatus of claim 1, wherein network controlling apparatus can maintain information from another network controlling apparatus, or extract from object identification information.

18. The apparatus of claim 6, wherein network controlling apparatus can transmit lookup information request to a gateway association with the help of route domain request.

19. The apparatus of claim 1, further comprising:

a first network controller can verify that where the receiving object is included in a first root domain.

20. The apparatus of claim 1, wherein when the receiving object is not included information in first domain then the network controlling apparatus can verify from the database.

9. A method of controlling a network using identification information of an object, the method comprising:

extracting identification information of a receiving object from received data; and

verifying, from a database, forwarding information that is stored in correspondence to the identification information when the receiving object is not included in a first domain; and

transferring the data to a gateway associated with a second domain designated by the forwarding information.

10. The method of claim 9, further comprising:

verifying that the receiving object is not included in the first domain when the extracted identification information is not retrieved from the database.

11. The method of claim 9, wherein the verifying comprises verifying, as the forwarding information, at least one of a routing hint including domain identification information of from a top level domain to a domain to which the receiving object is registered, domain identification information associated with the second domain, and an address of the gateway connected to the second domain.

12. The method of claim 9, further comprising:

extracting a routing hint corresponding to identification information of the receiving object from the data when the forwarding information is not verified from the database; and

transmitting a route search request to a gateway associated with at least one route domain included in the extracted routing hint, and determining, as the second domain, a route domain that transmits a response to the route search request to thereby transfer the data to the gateway associated with the second domain.

13. The method of claim 9, further comprising:

transmitting a lookup information request to a route domain having a relatively upper domain grade with respect to the first domain, and receiving forwarding information corresponding to identification information of the receiving object from a gateway associated with the route domain that receives the lookup information request, when the forwarding information is not verified from the database and a routing hint corresponding to identification information of the receiving object is not extracted from the data.

14. The method of claim 9, further comprising:

transmitting the data to the receiving object when the receiving object is included in the first domain.

21. The present invention can be recorded in computer-readable media including program instructions to implement various operations embodied by a computer.
