ABSTRACT = {In the Content-Centric Networking (CCN) architecture, popular content can be cached in some intermediate network devices while being delivered, and
the following requests for the cached content can be efficiently handled by the caches. Thus, how to design in-network caching is important for reducing
both the traffic load and the delivery delay. In this paper, we propose a caching framework of Prefix-based Popularity Prediction (PPP) for efficient caching
in CCN. PPP assigns a lifetime (in a cache) to the prefix of a name (of each cached object) based on its access history (or popularity), which is represented as
a Prefix-Tree (PT). We demonstrate PPP’s predictability of content popularity in CCN by both traces and simulations. The evaluation results show that PPP
can achieve higher cache hits and less traffic load than traditional caching algorithms (i.e., LRU and LFU). Also, its performance gain increases with users
of high mobility.},
