Abstract
Distribution of content between publishers and consumers is accomplished using an overlay network that may make use of XML language to facilitate content identification. The overlay network includes a plurality of routers that may be in communication with each other and the publishers and consumers on the Internet. Content and queries are identified by content descriptors that are routed from the originator to a nearest router in the overlay network. The nearest router, for each unique content descriptor, generates a hash identification of the content descriptor which is used by remaining routers in the overlay network to provide the appropriate functions with respect to the content descriptor. In particular, this allows all routers in the overlay network except the nearest router to properly route content without processing every content descriptor.
