Abstract (EN): CONVERGENCE features innovative technologies and ideas contributing to the evolution of the Internet into a network of people, “things” and media. This implies a strategic shift from the original “host-centric” concept to one of “content-centric” or “information-centric” networking. Against this background, CONVERGENCE proposes the enhancement of the Internet with a novel, content-centric, publish-subscribe service model based on the versatile digital item (VDI): a common container for all kinds of digital content, including digital representations of real world resources. VDIs will serve the needs of the future Internet, providing a homogeneous method for handling structured information, and incorporating security and privacy mechanisms. The CONVERGENCE framework subsumes the following areas of research: • definition of the VDI as a new fundamental unit of distribution and transaction; • new information-centric networking functionality, to complement or replace IP-address-based routing; • security and privacy protection mechanisms; • new open source middleware, including a community dictionary service to enable rich semantic searches; • applications, tested under real-life conditions. With CONVERGENCE, users can publish, search and subscribe to any content; wrap content (e.g. video) and its descriptions into a VDI, specify its name, set rights to it (e.g. who can see the video, where and for how much time), and publish it to the network; update or revoke content, even after it has been published, monitor its use, and communicate with people using it. The network knows the content name and makes sure users always access the copy closest to them; every node is a cache; handover is easy; multicast is natural, peer-to-peer is built-in, time/space-decoupling is possible. Search engines can exploit VDI metadata for indexing. Developers do not need to use proprietary/ad hoc solutions for common/supporting functionality as they can exploit CONVERGENCE’s middleware and network. Operators can use the network more efficiently, better control information transfer and related revenues flows, and simplify network design, operation and management by integrating in the network diverse functions, avoiding patches and stopgap solutions. Whether as text for graduate students working on the future of the Internet or resource for practitioners providing e-commerce or multimedia services and research scientists developing and defining new technologies and protocols for their use, CONVERGENCE reports and documentation will make a valuable contribution to the future shape of the Internet, with effects in many areas of modern technological life.
