The move towards a future Internet is today hindered by the mismatch between the host-oriented model, at thefoundation of the current network architecture, and the dominant content-oriented usage, centered on data dissemination and retrieval. Content-centric networking (CCN) brings a paradigm shift in the present Internet communication model by addressing named-data instead of host locations. Important features of such networks are the availability of built-in network storage and of receiver-driven chunk level transport, whose interaction significantly impacts overall system and user performance. In the talk, I will focus on the performance evaluation of CCN networks and present an analytical model of bandwidth and storage sharing under fairly general assumption on total demand, topology, content popularity and limited network resources. Further, an overview of the ongoing activities and the main research challenges in this area will be provided.
