Are Information-Centric Networks Video-Ready?

Abstract

Video constitutes the majority of all Internet traffic and its share is expected to grow. Any future Internet architecture with a chance at success should provide some tangible benefits for video applications. Information-Centric Networking (ICN) architectures were designed with the specific goal of improving content distribution on the Internet; thus, this paper attempts to answer the obvious question: is ICN appropriate and ready for video traffic and, if not, what is missing or should be modified? To this end, we consider two different ICN architectures, ContentCentric Networking (CCN) and Publish-Subscribe Internetworking (PSI), and examine their applicability to Video on Demand and Live Video Streaming applications. Our goal is to clarify what ICN already does well for video, what it still needs to do, and, most importantly, what it could or should do differently.
