Résumé

A Peer-to-Peer (P2P) network is decentralised and relies on end-users capacities for a good delivery of service. The more end-users are sharing the content, the more powerful the system is. P2P applications are now widely used for many services. But P2P systems are still based on a end-to-end con- nectivity on the current IP-based Internet. For few years, a new networking paradigm emerged, the Content-Centric Networking (CCN) approach. In CCN, the user just cares about the content, not about the node that provides it. It takes as input some features of the P2P systems, applying them in the network itself. However, current CCN system forwards messages based on a defined forwarding table, filled with the advertisements of content providers. It does not take into the consideration of the fact that end-users that requested the contents can cache them for a while and thus be the potential sources of content, as it is in a P2P system. In this paper, we propose to take into consideration of the caching capacities of end-users in the CCN design so as to improve the content delivery in a CCN network. This is achieved by the design of a content-aware dynamic downstream forwarding scheme, and an adaptation of the current way to fill the forwarding table. Our evaluation shows that exploiting the end-users P2P caching facilities allows to improve the efficiency to the CCN network by reducing the memory requirements of the CCN node and by improving the data delivery to end-users via a closer delivery.
