Deploying P2P Techniques to Provide VoD Services under Scheduled Video Delivery Paradigm

Abstract

In the past, the discussion of VoD services mainly focused on the on-demand paradigm, in which users are assumed and restricted to request a video for instantly viewing. This paradigm causes the inefficient utilization of the system resources and high rejection probability. In this paper, we address the problem of providing VoD services over peer-to-peer networks under Scheduled Video Delivery (SVD) paradigm, in which users are allowed to issue requests for instantly viewing or for later viewing. We propose an administrative organization to manage the relationship among peers, atop which a proposed novel delivery protocol is applied to take full advantage of the resources contributed by peers and the server. Due to the dynamics inherent in P2P networks, the fast failure recovery is critical to an approach of providing VoD services over P2P networks. Our proposed approach can make the users suffering failure recover quickly. Index Terms — VoD, SVD, P2P
