Time Aware Least Recent Used (TLRU) Cache Management Policy in ICN

TL;DR

This paper introduces a new cache eviction policy called Time Aware Least Recent Used (TLRU) tailored for Information Centric Networks, considering content popularity and usability time to improve cache management.

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.

Proposed policy adapts to content popularity and lifetime.

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.
