Abstract: An overlay network includes a virtual content server for representing a content provider in a virtual content network and at least a client having a membership in the virtual content network and a content path between the virtual content server and the client. Each node in the content path is also a member of the virtual content network and each link between nodes is provided by a tunnel to ensure trust and integrity at the content level.
