The authors present energy consumption models of Video-on-Demand (VoD) services delivered through newly proposed localized Hybrid Peer-To-Peer (HP2P) and localized Peer-Assisted Patching (PAP) with multicast video delivery methods over optical access networks. In this paper, the authors demonstrate through simulations that the localized PAP with multicast video delivery method consumes the lowest network transport energy for popular VoD channels while localized HP2P method consumes the lowest network transport energy for less popular channels. Nevertheless, both schemes outperform the conventional CDN delivery method in term of overall network energy consumption.
