Publish/subscribe over information centric networks: A Standardized approach in CONVERGENCE

Originally conceived as a “network of hosts”, the Internet is evolving into an Internet of services, an Internet of media, an Internet of people and an Internet of “things”. This implies a strategic shift from “host-centric” to “content-centric” and “data-centric” networking. CONVERGENCE proposes to enhance the Internet with a novel, information-centric, publish-subscribe service model, based on the Versatile Digital Item (VDI): a common container for all kinds of digital content, derived from the MPEG-21 standard. Results in terms of standardization activities and software implementation are presented.
