Abstract
The Information-Centric Networking ICN architectures proposed to overcome the problems of the actual internet architecture. One of the main straight points of the ICN architectures is in-network caching. The effectiveness of the adopted caching strategy, which manages and decides where to store them, influences the performance of the ICN.
However, the major issue that faces the caching strategies in the ICN architectures is the strategic selection of the cache routers to store the data through its delivery path. This will reduce congestion, optimize the distance between the consumers and the required data furthermore improve latency and alleviate the viral load on the servers. In this paper, we propose a new efficient caching strategy for the Named Data Networking architecture NDN named NECS, which is the most promising architecture between all the ICN architectures.
The proposed strategy reduces the traffic redundancy, eliminates the useless replication of contents, and improves the replay time for users due to the strategic position of cache routers.
Besides, we evaluate the performance of this proposed strategy and compare it with three other NDN caching strategies, using the simulator network environment NdnSIM. Based on the simulations carried out, we obtained interesting and convincing results.
