CLIC: a CLIque-based cooperative Caching for Content Centric Networking
Résumé
Due to the Internet usage evolution over these last years, the current IP-based architecture becomes heavier and less efficient for providing some Internet services. In order to face this shortcoming, “Content Centric Networking” has been proposed. One of its important features is to exploit in-network caching as a mean to improve network's performance and services' scalability. However, in most of the existing CCN-based approaches, several copies of the same content are present within the network, which reduces its efficiency. In this work, we propose a “CLIque-based cooperative Caching” (CLIC) strategy, which basically consists in detecting cliques within the network topology to manage more efficiently the contents in the network. The main motivation of the proposed solution is to eliminate contents' redundancy between neighboring nodes while promoting the most popular contents. This approach guarantees enough copies of popular files within the network while maximizes the number of distinct content items. We evaluate the proposed scheme through simulation. The obtained results show significant improvements in terms of cache management and network performance (delay reduction).
