Recently, HTTP Adaptive Streaming (HAS) is attracting a lot of attention as the state-of-art technology for video transport. HAS dynamically adjusts the quality of a video stream according to a user¡¯s bandwidth and CPU. Also, HAS is HTTP-based which enables very high penetration. Content-Centric Networking (CCN) is a novel cmmunication paradigm that integrates content delivery as a native network primitive. However, it is unclear how CCN would perform in presence of dynamic applications such as HAS. In this work, we shed some light on the interaction of adaptive video streaming with CCN. We adopt an experimental approach: we deploy a test-bed where we can run Smooth Streaming, one of the most popular HAS solutions, over CCNx, the reference implementation of CCN. Then, we perform several experiments to reveal behavior of adaptive streaming over CCN in presence of different network parameters, cache sizes and replacement policies.
