Content-Based Publish/Subscribe Networking and Information-Centric Networking

The notion of content-centric networking is based on an addressing scheme wherein the send and receive communication primitives identify content rather than network locations. This addressing scheme is motivated by social, application-level considerations, as much as by technical, network-level considerations. At a high-level, communication would be more effective if consumers could simply specify what content they intend to receive as opposed to from where that content might be retrieved. At the network-level, an addressing scheme that identifies content as op-posed to location would allow the network to operate more efficiently by duplicating and caching content around the network, since it is the delivery of content that matters, not where that content resides.
