Abstract : Periodic broadcasting schemes are the most promising solution to building large-scale video streaming services. Existing periodic broadcasting schemes are all built around the traditional client-server model. This paper proposes a radically different architecture where only end-user hosts are used to build the periodic broadcasting system, thereby eliminating the need for a central server or even a service provider. Two unique problems pertaining to this decentralized, peer-to-peer architecture are addressed: transmission scheduling and peer synchronization. A new decentralized synchronization algorithm is proposed and results obtained from simulations confirm the architectureˇ¦s feasibility and performance.
