Performance Analysis of Caching and Forwarding Strategies in Content Centric Networking

International audienceContent-Centric Networking (CCN) is a promising implementation of the Information-Centric Networking architecture that was introduced to address recent needs related to the proliferation of multimedia traffic in the Internet. One of the fundamental features of CCN is in-network caching that aims to reduce delays, optimize bandwidth, and resource usage. Designing better in-network caching strategies along with optimal replacement policies is a challenging research issue in CCN. Moreover, the lack of a common comparison framework has obfuscated the real performance of these strategies when compared with each other. Based on realistic assumptions and a common environment, this paper gives a comprehensive view on performance comparison of popular caching strategies and replacement policies employed in CCN, while considering different forwarding strategies and multiple network topologies
