Methods and systems for content access and distribution

摘要

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.

1. A system for distributing content, the system comprising:
a first router including a processor that executes instructions to perform operations, the operations comprising:
generating a first publisher interface list, wherein the first publisher interface list includes a first link to the first publisher;generating a tuple comprising a first content descriptor corresponding to a first content published by the first publisher, the first publisher interface list, a first hash of the first content descriptor; andtransmitting the tuple to a second router, wherein a query received by the second router that corresponds to the first content descriptor is routed to the first router based on the first publisher interface list, wherein a second content descriptor corresponding to a second content is received by the second router, wherein the second content descriptor, the second content, and a second hash of the second content descriptor match the first content descriptor, the first content, and the first hash respectively.
