Experimenting with services over an information-centric integrated satellite-terrestrial network

The recent paradigm shift in the Internet´s usage, from the host-centric to a content-centric communication model, where users request information irrespectively of its location, is coupled with an increasing need for converged and seamless access over heterogeneous wired and wireless networks. By integrating satellite communication components into a publish-subscribe Information-Centric Networking (ICN) architecture, we jointly exploit the capabilities and advantages of each: transparent use of terrestrial multicasting and satellite broadcasting, content-based traffic engineering, multipath transfer, in-network caching capabilities, and seamless mobility. Experimenting over a realized integrated-terrestrial ICN testbed, we demonstrate and illustrate key functionalities and gains for various services and applications.
