US Patent 7720060 Information dissemination system having an information layer

An information dissemination system has at least one node acting as a data source, at least one node acting as a data recipient, and an information layer residing on all of the nodes in a system. The information layer receives a generic utility function from an application on the node acting as a data source wanting to propagate information, uses the generic utility function at the node acting as data source to produce a microutility and uses the microutility on non-data source nodes of the system to propagate the information through the system to any recipients based upon the microutility.
