Title
A Measurement Study of a Peer-to-Peer Video-on-Demand System
Abstract
Despite strong interest in P2P video-on-demand (VoD) services, existing studies are mostly based on simulation and focus on areas such as overlay topology. Little is known about the effectiveness of P2P in VoD systems and the end user experience. In this paper we present a comprehensive study of these issues using the two-month logs from a deployed experimental P2P VoD system over CERNET1. Our key findings are: (1) the key factor is the popularity of channels and a moderate number of concurrent users can derive satisfactory user experience. However, good network bandwidth at peers and adequate server provisioning are critical. (2) a simple prefetching algorithm can be effective to improve random seeks. Overall, we believe that it is feasible to provide a cost- effective P2P VoD service with acceptable user experience, and there is a fundamental tradeoff between good experience and system scalability.
