A Dive Into the Caching Performance of Content Centric Networking
Content Centric Networking (CCN) is a promising architecture for the diffusion of popular content over the Internet. Radically departing from content-oblivious IP networks, CCN pushes content-awareness down the networking stack. By relying on in-network caching, CCN reduces the overall network load, as requests no longer need to travel until the content originator, but are typically served by a closer CCN router along the path. While the system design of CCN is sound, gathering a reliable estimate of CCN caching performance in the current Internet scenario is challenging, due to its large scale and to the lack of agreement in some critical elements of the evaluation setup.
