Leveraging replication in content-centric networks

This paper focuses on the communication functionalities of content-centric networks. More especially, we take advantage of the widespread availability of content as today data objects may be replicated or moved at several locations to minimize content access time or to provide resiliency. We propose a scalable interdomain routing architecture designed to meet the needs of data-intensive applications. Our protocol complements CCN´s routing framework with the ability to discover routes that allow users to retrieve replicated content from the most efficient location. The distinctive feature of our approach lies in the use of the caching capabilities of content routers to store and maintain the routes discovered towards the closest replicas. Our simulation results show an increase in content access efficiency by minimizing retrieval time and by maximizing the bandwidth demand.
