Abstract

A method for disseminating content over an overlay network having a plurality of routers in communication with providers and consumers of content is disclosed. A router in the overlay network receives a content descriptor corresponding to a query for content from a node, and generates a subscriber interface list based on the query for the content. The subscriber interface list is transmitted to a plurality of subsequent routers in the overlay network, wherein a content identified by the subsequent routers that correspond to the query will be routed to the router based on the subscriber interface list. The router receives first and second documents corresponding to the query for the content from the node. If the second document is the duplicate, the router deletes the second document and transmits the first document to the node or if not the router transmits both the first and second documents to the node.

Claims

1. A system, comprising:

a memory that stores instructions;

a processor that executes the instructions to perform operations, the operations comprising;

determining if multiple coordinator routers are attempting to flood a first content descriptor in an overlay network;

selecting, if the multiple coordinator routers are attempting to flood the first content descriptor, a first router as a coordinator router for the first content descriptor based on the first router having a smallest hash identifier when compared to other routers of the multiple coordinator routers;

generating, by utilizing the first router, a tuple comprising the first content descriptor which corresponds to first content;

transmitting, by utilizing the first router, the tuple to a second router so as to form a path for the first content to be transmitted; and

transforming, by utilizing the overlay network and based on a credential of a user requesting the first content, the first content by filtering a portion of the first content from the first content.

2. The system of claim 1, wherein the operations further comprise generating a publisher interface list.

3. The system of claim 1, wherein the operations further comprise receiving, at the second router, a query that corresponds to the first content descriptor.

4. The system of claim 3, wherein the operations further comprise routing the query to the first router.

5. The system of claim 1, wherein the operations further comprise receiving, at the second router, a second content descriptor corresponding to second content.

6. The system of claim 1, wherein the operations further comprise identifying, by utilizing the first router, the first router as the coordinator router.

7. The system of claim 1, wherein the operations further comprise routing the first content descriptor to other routers in the overlay network according to the tuple.

8. The system of claim 1, wherein the operations further comprise determining whether the first content descriptor is a duplicate entry.

9. The system of claim 8, wherein the operations further comprise transmitting the tuple to the second router after determining that the first content descriptor is the duplicate entry.

10. The system of claim 1, wherein the operations further comprise receiving the first content descriptor.

11. The system of claim 1, wherein the operations further comprise filtering an additional portion of the first content from the first content based on a relevance score of the additional portion of the first content.

12. The system of claim 1, wherein the operations further comprise determining a relevance score for the first content.

13. A method, comprising:

determining, by utilizing instructions from a memory that are executed by a processor, if multiple coordinator routers are attempting to flood a first content descriptor in an overlay network;

selecting, if the multiple coordinator routers are attempting to flood the first content descriptor, a first router as a coordinator router for the first content descriptor based on the first router having a smallest hash identifier when compared to other routers of the multiple coordinator routers;

creating, by utilizing the first router, a tuple comprising the first content descriptor which corresponds to first content;

forwarding, by utilizing the first router, the tuple to a second router so as to form a path for the first content to be transmitted; and

transforming, by utilizing the overlay network and based on a credential of a user requesting the first content, the first content by filtering a portion of the first content from the first content.

14. The method of claim 13, further comprising determining a relevance score for the first content.

15. The method of claim 13, further comprising distributing the first content over the overlay network.

16. The method of claim 13, further comprising generating, at the first router, a hash of the first content descriptor.

17. The method of claim 13, further comprising determining whether the first content descriptor is a duplicate entry.

18. The method of claim 13, further comprising routing the first content descriptor to additional routers in the overlay network based on the tuple.

19. The method of claim 13, further comprising receiving, at the second router, a query that corresponds to the first content descriptor.

20. A system, comprising:

a memory that stores instructions;

a hardware processor that executes the instructions to perform operations, the operations comprising;

determining if multiple coordinator routers are attempting to flood a first content descriptor in an overlay network;

selecting, if the multiple coordinator routers are attempting to flood the first content descriptor, a first router as a coordinator router for the first content descriptor based on the first router having a smallest hash identifier when compared to other routers of the multiple coordinator routers;

transmitting, by utilizing the first router, a tuple to a second router so as to form a path for first content to be transmitted, wherein the tuple comprises the first content descriptor which corresponds to the first content; and

transforming, by utilizing the overlay network and based on a credential of a user requesting the first content, the first content by filtering a portion of the first content from the first content.
