Analysis of BitTorrent-Like Protocols for On-Demand Stored Media Streaming

Category: Software and Web Development, Networking and Communications

Overview This paper develops analytic models that characterize the behavior of on-demand stored media content delivery using BitTorrent-like protocols. The models capture the effects of different piece selection policies, including Rarest-First and two variants of In-Order. The models provide insight into transient and steady-state system behavior, and help explain the sluggishness of the system with strict In-Order streaming. The paper uses the models to compare different retrieval policies across a wide range of system parameters, including peer arrival rate, upload/download bandwidth, and seed residence time. The paper also provides quantitative results on the startup delays and retrieval times for streaming media delivery. The results provide insights into the optimal design of peer-to-peer networks for on-demand media streaming.
