On the Incremental Deployment of Overlay Information Centric Networks
It has long been realized that the proliferation of information-centric applications and services must be reflected in a corresponding shift of the underlying Internet architecture. Even though users increasingly focus on the desired information, the underlying network still focuses on the endpoints providing/consuming this information and in many cases this mismatch has resulted in an inefficient utilization of network resources, as demonstrated by Peer-To-Peer (P2P) and file sharing applications. In view of this situation, many research projects have focused on the investigation of alternative networking models centered around information. However, less attention has been paid to the transition process from the current end host centric model to an information centric one.
