Abstract :
We present energy consumption models of video-on-demand (VoD) services delivered through newly proposed localized hybrid peer-to-peer (P2P) and localized peer-assisted patching with multicast video delivery methods over optical access networks. In this paper, we demonstrate through simulations that the localized peer-assisted patching with multicast video delivery method consumes the lowest network transport energy for popular VoD channels while localized hybrid P2P method consumes the lowest network transport energy for less popular channels. Nevertheless, both schemes outperform the conventional server centric content distribution network in term of overall network energy consumption.
