A recent popularity based dynamic cache management for Content Centric Networking

One of the key research items of Content-Centric Networking is how to develop more efficient cache replacement policies, and most of the existing approaches have their foundations with dated web environments while considering little of the dynamicity of user interests. In this paper, we propose a new cache replacement policy, named as the “Recent Usage Frequency (RUF).” In order to deal with dynamic traffic patterns and alleviate temporal traffic variations, new position of popularity monitoring is suggested and the exponential weighted moving average is utilized. Performance evaluation shows that the proposed scheme outperforms the existing replacement policies in efficiency and resiliency.
