OpenCache: exploring efficient and transparent content delivery mechanisms for video-on-demand

Abstract

Watching 'on-demand' video content is a popular activity facilitated by the Internet. Existing distribution methods typically rely on unicast flows to deliver this media. This can be inefficient if identical content is delivered at a later point in time. We propose a caching platform to store content locally whilst maintaining the underlying delivery method. This paper introduces OpenCache, a prototype network-aware caching platform that utilises emerging OpenFlow technology.
