Dynamic viewing pattern exploitation in Peer-to-Peer Video-on-Demand

Abstract

Unstructured BitTorrent-like Peer-to-Peer networks have been extensively studied as an important enabling technology for Video-on-Demand. While most studies maintain the pull-based nature of unstructured Peer-to-Peer networks, recent ones are investigating the combination of pull and push operations. The goal of the proposed push/pull protocols is to make more effcient use of the available bandwidth, however, this paper proposes a different use, the exploitation of users' viewing patterns (random seek patterns) in Video-on-Demand applications. As viewing pattern exploitation has not been given signif cant attention so far, we propose a scheme to prioritize chunk distribution based on the video's points of interest. © 2011 IEEE.
