Executive Summary

Building a scalable Video On Demand (VOD) architecture is essential for the optimization of the VOD service cost and to support a very large VOD content library. The Peer-To-Peer (P2P) VOD architecture works towards achieving this goal, by distributing the video files to the user's set-top boxes at the network edge. The details of such system, however, including numerous operational issues remain to be resolved. This paper investigates the network bandwidth requirements of a peer-to-peer VOD service architectures system. A network mathematical model is developed to analyze the key-parameters that have influence on the P2P network bandwidth requirement.
