1. A method for disseminating content over an overlay network having a plurality of routers in communication with providers and consumers of content, the method comprising: receiving, at a first router in the overlay network, a first content descriptor corresponding to a first content published by a first publisher; generating, at the first router, a first hash of the first content descriptor; generating, at the first router, a first publisher interface list, wherein the first publisher interface list includes a first link to the first publisher; generating, at the first router, a tuple comprising the first hash, the first content descriptor and the first publisher interface list; transmitting the tuple to a plurality of subsequent routers in the overlay network, wherein queries received by the subsequent routers that correspond to the first content descriptor will be routed to the first router based on the first publisher interface list; receiving, at one of the plurality of subsequent routers, a second content descriptor corresponding to a second content from a second publisher, wherein the second content descriptor, the second content from the second publisher, and a second hash of the second content descriptor are the same as the first content descriptor, the first content from the first publisher, and the first hash; and updating the first publisher interface list in only the one of the plurality of subsequent routers to create a second publisher interface list including a second link to the second publisher.
