Video Streaming over Content Centric Networking: Experimental Studies on PlanetLab

摘要

Video streaming is one of the most popular Internet applications for years. To improve content availability and scalability, CDN and P2P networking have been widely used. However, the current Internet architecture, which relies on a host-based communication, has no ability to leverage caching at the network level. Recently, Content Centric Networking (CCN) has been emerged as a new networking paradigm. The communication of CCN focuses on the named contents instead of the IP addresses. This paper provides a framework for enabling video streaming over CCN. We performed experiments using CCNx on the PlanetLab to explore how an overlay path and a chunk size affect the streaming quality. Furthermore, we study the deployment of MPEG-DASH to achieve adaptive bit-rate streaming over CCN, which reveals additional challenge.
