ABSTRACT:

Peer-to-peer (P2P) streaming has been widely deployed over the Internet. A streaming system typically has multiple channels, and peers might form multiple teams for content distribution. In this paper, we have a tendency to propose a distributed overlay framework (called SMesh) for dynamic teams where users may frequently hop from one cluster to another whereas the whole pool of users remain stable. SMesh initial builds a relatively stable mesh consisting of all hosts for control messaging. The mesh supports dynamic host joining and leaving, and can guide the construction of delivery trees. Using the Delaunay Triangulation (DT) protocol for example, we show a way to construct an economical mesh with low maintenance cost. We tend to more study various tree construction mechanisms primarily based on the mesh, as well as embedded, bypass, and intermediate trees. Through simulations on Internet-like topologies, we show that SMesh achieves low delay and low link stress.
