Abstract

One embodiment of the present invention provides a system for retrieving a content collection over a network. During operation, the system determines additional information associated with the piece of content that is needed for consumption of the content collection; generates a plurality of Interests, which includes at least one Interest for a catalog of the content collection and at least one Interest for the additional information; and forwards, concurrently, the plurality of Interests, thereby facilitating parallel retrieval of the content collection and the additional information.

Claims

1. A computer-executable method for retrieving a content collection that includes a plurality of content objects over a content-centric network, the method comprising:

determining, by a computer, content-access information that is needed to consume the content collection;

generating a plurality of interest packets, which include at least a first interest packet for a catalog of the content collection, a second interest packet for a content object within the content collection, and a third interest packet for the content-access information, wherein the catalog of the content collection includes an ordered list identifying the plurality of content objects within the content collection; and

forwarding, concurrently, the plurality of interest packets comprising the first interest packet for the catalog, the second interest packet for the content object, and the third interest packet for the content-access information over the content-centric network to facilitate parallel retrieval of the content collection, the catalog of the content collection, and the content-access information.

2. The method of claim 1, wherein the content-access information includes one or more of:

authentication and/or decryption information associated with the catalog;

authentication and/or decryption information associated with the content collection; and

authentication revocation information.

3. The method of claim 1, further comprising generating an interest packet for the content collection by including, in the generated interest packet, one or more of:

user credential information and payment information.

4. The method of claim 1, wherein concurrently forwarding the interest packets involves:

forwarding at least one interest packet for the content-access information to a trust authority.

5. The method of claim 1, wherein the interest packets are content-centric networking (CCN) Interests, and wherein a respective CCN Interest specifies a name prefix.

6. The method of claim 1, further comprising:

receiving responses to the plurality of interest packets; and

caching the received responses.

19. The method of claim 1, wherein concurrently forwarding the interest packets involves forwarding at least one interest packet for a content object within the content collection.

7. A non-transitory computer-readable storage medium storing instructions that when executed by a computing device cause the computing device to perform a method for retrieving a content collection that includes a plurality of content objects over a content-centric network, the method comprising:

determining, by a computer, content-access information that is needed to consume the content collection;

generating a plurality of interest packets, which include at least a first interest packet for a catalog of the content collection, a second interest packet for a content object within the content collection, and a third interest packet for the content-access information, wherein the catalog of the content collection includes an ordered list identifying the plurality of content objects within the content collection; and

forwarding, concurrently, the plurality of interest packets comprising the first interest packet for the catalog, the second interest packet for the content object, and the third interest packet for the content-access information over the content-centric network to facilitate parallel retrieval of the content collection, the catalog of the content collection, and the content-access information.

8. The computer-readable storage medium of claim 7, wherein the content-access information includes one or more of:

authentication and/or decryption information associated with the catalog;

authentication and/or decryption information associated with the content collection; and

authentication revocation information.

9. The computer-readable storage medium of claim 7, wherein the method further comprises generating an interest packet for the content collection by including in the generated interest packet one or more of:

user credential information and payment information.

10. The computer-readable storage medium of claim 7, wherein concurrently forwarding the interest packets involves:

forwarding at least one interest packet for the content-access information to a trust authority.

11. The computer-readable storage medium of claim 7, wherein the interest packets are content-centric networking (CCN) Interests, and wherein a respective CCN Interest specifies a name prefix.

12. The computer-readable storage medium of claim 7, wherein the method further comprises:

receiving responses to the plurality of interest packets; and

caching the received responses.

20. The computer-readable storage medium of claim 7, wherein concurrently forwarding the interest packets involves forwarding at least one interest packet for a content object within the content collection.

13. A computer system for retrieving a content collection that includes a plurality of content objects over a content-centric network, the system comprising:

a processor; and

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

determining, by a computer, content-access information needed to consume the content collection;

generating a plurality of interest packets, which include at least a first interest packet for a catalog of the content collection, a second interest packet for a content object within the content collection, and a third interest packet for the content-access information, wherein the catalog of the content collection includes an ordered list identifying the plurality of content objects within the content collection; and

forwarding, concurrently, the plurality of interest packets comprising the first interest packet for the catalog, the second interest packet for the content object, and the third interest packet for the content-access information over the content-centric network to facilitate parallel retrieval of the content collection, the catalog of the content collection, and the content-access information.

14. The computer system of claim 13, wherein the content-access information includes one or more of:

authentication and/or decryption information associated with the catalog;

authentication and/or decryption information associated with the content collection; and

authentication revocation information.

15. The computer system of claim 13, wherein the method further comprises generating an interest packet for the content collection by including in the generated interest packet one or more of:

user credential information and payment information.

16. The computer system of claim 13, wherein concurrently forwarding the interest packets involves:

forwarding at least one interest packet for the content-access information to a trust authority.

17. The computer system of claim 13, wherein the interest packets are content-centric networking (CCN) Interests, and wherein a respective CCN Interest specifies a name prefix.

18. The computer system of claim 13, wherein the method further comprises:

receiving responses to the plurality of interest packets; and

caching the received responses.

21. The computer system of claim 13, wherein concurrently forwarding the interest packets involves forwarding at least one interest packet for a content object within the content collection.
