Keynote 2: Information-centric networking: Overview, current state and key challenges

Information-Centric Networking (ICN), also referred to as content-centric, content-aware or data-oriented networking is seen as an emerging paradigm that tries to re-focus communications, centering on content access rather than on host-to-host interaction as is the case today. The proliferation of user-generated content and the fact that the vast majority of interactions over the Internet concern media content access has led researchers to think of new communication models in which information/content comes on center stage and is accessed in a location-independent fashion; in addition, the underlying network is aware of the content characteristics and optimizes delivery accordingly. The resulting communications paradigm is receiver-driven, with “time-phased” multicasting and in-network caching being the norm. The network infrastructure becomes more intelligent, with application logic potentially executing within the network in order to support demanding media applications that are not possible today. Summary form only given. This presentation will start with an overview of information-centric networking; it will present the state-of-the-art in the relevant research activities and will consider the current state and key challenges. The management challenges of the expected fluid and more dynamic network infrastructure will also be specially considered.
