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 real-time 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
