P2P is successful in various multimedia applications such as On-demand/live streaming due to the efficient upload bandwidth usage among participating peers which offloads server request thereby saving bandwidth as system size scales up. Many designs were proposed for P2P multimedia streaming systems, including the most promising tree/mesh overlays. In this paper, we propose MERIT as an integrated framework for scalable mesh-based P2P multi-streaming whose design objective is to preserve content diversity as well as optimizing start-up delay while satisfying the in-/out- bound bandwidth constraints. We formulate our design goals as an optimization problem and start with a centralized heuristic exploiting the global knowledge of peers. We then present a decentralized version of our algorithm which is scalable and follows similar design principles as the centralized one. Simulation results indicate that our heuristics outperform state-of-the-art approaches by improving streaming quality and start-up delay with efficient utilization of bandwidth resources at each peer.
