Contribution
The paper defines key characteristics for ICN cache eviction policies, analyzes existing policies, and proposes the TLRU scheme optimized for ICN requirements.
Findings
TLRU outperforms traditional policies in ICN scenarios.
Analysis shows the importance of content usability time.

Abstract
The information centric networks (ICN) can be viewed as a network of caches. Conversely, ICN type of cache networks has distinctive features e.g, contents popularity, usability time of content and other factors inflicts some diverse requirements for cache eviction policies. In this paper we defined four important characteristics of a suitable eviction policy for ICN. We analysed well known eviction policies in view of defined characteristics. Based upon analysis we propose a new eviction scheme which is well suitable for ICN type of cache networks.
