EFFICIENT VIDEO DISSEMINATION IN STRUCTURED HYBRID P2P NETWORKS

In this paper, we propose a structured hybrid P2P Mesh for optimal video dissemination from a single source node to multiple receivers in a bandwidth-asymmetric network such as Digital Subscriber Line (DSL) access network. Our hybrid P2P structured mesh consists of one or more Supernodes responsible for node and mesh management and a large number of streaming nodes, Peers. The peers are interconnected in a special manner designed for streaming and realtime video dissemination and are responsible for the actual data delivery. Our proposed hybrid P2P structured mesh is designed to achieve scalability, low delay and high throughput. Our experimental Internet-wide system consisting of PlanetLab nodes demonstrates the aforementioned qualities. 2
