A Content Eviction Mechanism for Information-centric Networking

Information-Centric Networking, which is also called Content-Centric Networking (CCN), is the vowing candidate for the Future Internet. ICN has many aspects, e.g., Naming, Routing, and Caching, etc. but in the past five years, caching gained a tremendous attraction by the research community. In ICN, caching is of two types, i.e., off-path caching and on-path caching. On-path caching is also known as in-network caching, where routers cache content items for some time before sending them to the desired destination(s). For ICN caching, many strategies have been proposed, for example, Leave Copy Everywhere (LCE), Leave Copy Down (LCD), Centrality-based caching, Most Popular Caching (MPC), and many more. The authors of MPC claim that it outperforms all existing strategies, however, it utilizes maximum memory during content caching. In this paper, we propose a mechanism for content caching, named Content Eviction Mechanism (CEM), and compare our results with LCE and MPC in OPNET Modeler 18.0. Our simulation results show that CEM predominantly outperforms LCE and MPC.
