Enhancing P2P Stream Management through Effective Stream Sharing Approaches

The StreamGlobe framework presents an innovative P2P data stream management system, addressing the inefficiencies of traditional approaches that lead to redundant data transmissions and increased network traffic. By implementing a publish and subscribe model with optimized stream sharing, StreamGlobe minimizes unnecessary computations and enhances throughput, especially in variable network topologies. This approach showcases significant benefits such as reduced peer load, early filtering of data, and better handling of real astrophysical data. Join us for demonstrations that explore these advancements and their applications in network scenarios.
