Evaluation of Adaptive Video Streaming over Information-Centric Networking (resubmission of #2064 in SIRD table)

Most of today's Internet traffic consists of video transported by HTTP Adaptive Streaming (HAS). 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. Information-Centric Networking (ICN) is a novel communication paradigm that integrates content delivery as a native network primitive. However, it is unclear how ICN 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 ICN. We adopt an experimental approach: we deploy a test-bed where we can run Smooth Streaming, one of the most popular HAS solutions, over NDN, one of the most popular ICN designs. Then, we perform several experiments to reveal behavior of adaptive streaming over ICN in presence of different network parameters, cache sizes and replacement policies.
