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.
