Abstract

One embodiment provides a system that facilitates associating consumer states with interests in a Content-Centric Network (CCN). During operation, the system generates an interest for a content object comprising a name of the content object in a remote node. The name in the interest is location independent and uniquely identifies the content object in the CCN. The interest is routed in the CCN based on the name. The system also associates the consumer states, which are associated with the content object, with the interest.

Claims

1. A computer-executable method, comprising:

generating, by a computing device, an interest for a content object comprising a name of the content object in a remote node, wherein the name in the interest is location independent and uniquely identifies the content object in a Content-Centric Network (CCN), and wherein the interest is routed based on the name in the CCN; and

associating consumer states with the interest, wherein the consumer states are associated with the content object.

2. The method of claim 1, further comprising:

generating the consumer states; and

generating a state identifier for the consumer states.

3. The method of claim 2, further comprising:

creating a state content object of the consumer states; and

associating the state identifier with the state content object.

4. The method of claim 3, wherein associating the state identifier with the state content object further comprises assigning a network name to the state content object based on the consumer state identifier.

5. The method of claim 4, wherein associating the consumer states with the interest comprises one or more of:

embedding the consumer states in the interest;

embedding the state content object in the interest;

encoding the state identifier in the interest;

encoding the name of a state content object in the interest;

encoding the consumer state identifier in a content object name in the interest; and

encoding the state content object a content object name in the interest.

6. The method of claim 5, further comprising caching the consumer states.

7. The method of claim 6, wherein generating the consumer states further comprises:

calculating a difference between new consumer states and the consumer states;

including the different in the interest and one or more of;

the state identifier of the consumer states, an identifier of the new consumer states, and an identifier of the difference.

8. A non-transitory computer-readable storage medium storing instructions that when executed by a computer cause the computer to perform a method, the method comprising:

generating an interest for a content object comprising a name of the content object in a remote node, wherein the name in the interest is location independent and uniquely identifies the content object in a Content-Centric Network (CCN), and wherein the interest is routed based on the name in the CCN; and

associating consumer states with the interest, wherein the consumer states are associated with the content object.

9. The non-transitory computer-readable storage medium of claim 8, wherein the method further comprises:

generating the consumer states; and

generating a state identifier for the consumer states.

10. The non-transitory computer-readable storage medium of claim 9, wherein the method further comprises:

creating a state content object of the consumer states; and

associating the state identifier with the state content object.

11. The non-transitory computer-readable storage medium of claim 10, wherein associating the state identifier with the state content object further comprises assigning a network name to the state content object based on the consumer state identifier.

12. The non-transitory computer-readable storage medium of claim 11, wherein associating the consumer states with the interest comprises one or more of:

embedding the consumer states in the interest;

embedding the state content object in the interest;

encoding the state identifier in the interest;

encoding the name of a state content object in the interest;

encoding the consumer state identifier in the interest; and

encoding the state content object in the interest.

13. The non-transitory computer-readable storage medium of claim 12, wherein the method further comprises caching the consumer states.

14. The non-transitory computer-readable storage medium of claim 13, wherein generating the consumer states further comprises:

calculating a difference between new consumer states and the consumer states;

including the different in the interest and one or more of;

the state identifier of the consumer states, an identifier of the new consumer states, and an identifier of the difference.

15. A computer system, comprising:

a processor;

a storage device coupled to the processor and storing instructions that when executed by a computer cause the computer to perform a method, the method comprising;

generating an interest for a content object comprising a name of the content object in a remote node, wherein the name in the interest is location independent and uniquely identifies the content object in a Content-Centric Network (CCN), and wherein the interest is routed based on the name in the CCN; and

associating consumer states with the interest, wherein the consumer states are associated with the content object.

16. The computer system of claim 15, wherein the method further comprises:

generating the consumer states; and

generating a state identifier for the consumer states.

17. The computer system of claim 16, wherein the method further comprises:

creating a state content object of the consumer states; and

associating the state identifier with the state content object.

18. The computer system of claim 17, wherein associating the state identifier with the state content object further comprises assigning a network name to the state content object based on the consumer state identifier.

19. The computer system of claim 18, wherein associating the consumer states with the interest comprises one or more of:

embedding the consumer states in the interest;

embedding the state content object in the interest;

encoding the state identifier in the interest;

encoding the name of a state content object in the interest;

encoding the consumer state identifier in the interest; and

encoding the state content object in the interest.

20. The computer system of claim 19, wherein the method further comprises caching the consumer states.

21. The computer system of claim 20, wherein generating the consumer states further comprises:

calculating a difference between new consumer states and the consumer states;

including the different in the interest and one or more of;

the state identifier of the consumer states, an identifier of the new consumer states, and an identifier of the difference.
