The Internet architecture, based on end-to-end connec- tions, faced difficulties to efficiently deliver the always increasing number of contents. Content Delivery Networks (CDN) were de- ployed in the last years to improve the delivery and are nowadays largely used. Recent research works propose a new networking architecture, more adapted to the current Internet usage (end- users just cares about the contents they want and no about the endpoint that provides it), the Content-Centric Networking (CCN), aiming at replacing the IP paradigm. CCN is investigated by the research community for few years, and some demonstrators have been developed to prove its feasibility. However, up to now, none have addressed the CDN use-case. In this paper, we show that the current CCN design, which does not allow negative reply, is not suited for interconnection with the CDN network. We then propose the use of two new tables in the CCN nodes that are interconnected to the CDN servers, in order to detect possible miss in the CDN server and subsequently forward the request for missing contents toward the original server instead of the CDN surrogate. The evaluation we have performed highlight that the integration of those two new tables does not incur an increase of the memory requirement and thus a cost in the node. The proposed solution is then a viable solution in order to make CCN network work in close cooperation with CDN networks, each one keeping its specific business models and functions, i.e., the transport for the CCN, the storage for the CDN.
