NECS-based Cache Management in the Information Centric Networking

—Information Centric Networking (ICN) architectures propose to overcome the problem of Internet architecture. The main straight point of such architectures is the in-network caching. The efficiency of the adopted caching strategy influences the ICN performance. It manages the contents in the network and decides where to cache them. The major issue is the strategic selection of the cache routers to store the data on delivery path. This will reduce congestion, optimize the distance between the consumers and required data, improve latency, and alleviate the viral load on the servers. In this paper, we propose a New Efficient Caching Strategy for Named Data Networking (NDN), named NECS. The NDN is the most promising architecture among all the ICN architectures. The NECS strategy reduces the traffic redundancy, eliminates the useless contents replication, and improves the replay time for users, due to the strategic cache routers selection. We carried out extensive experiments to evaluate the NECS performances against other caching strategies. The results of our conducted simulations revealed that the NECS strategy has interesting and convincing performances in many aspects and records high cache-hit ratio. © 2021. All Rights Reserved.
