Abstract
With the explosive increase in Internet Contents, the Internet usage is shifting from host-to-host model to content dissemination model, e.g. video content accounts for the majority of Internet traffics. ISPs, content providers and other third parties have already deployed CDNs (content delivery networks) to improve user experience. However, as an ad-hoc solution to the content dissemination problem, CDNs still face big challenges, such as complicated control plane. With a fundamental change in network architecture, CCN (content centric network) incorporates content delivery functions in its network layer, and appears to be a most promising solution to this problem. In this paper, we construct comparable CDN and CCN testbeds separately and systematically compare the content delivery of CDN and CCN.
