The investigation around the use of peer-to-peer in IPTV environments goes on. The debate about the best compromise between the cost reduction offered by the Peer-To-Peer (P2P) approach and the quality requirements by the mass market is still open. Though some successful protocols are already worldwide used, there are still issues and optimization problems to solve. This paper has been the deployment on PlanetLab (Plab) of a large testbed in order to investigate the performance of [P2P client - streaming player] systems in static and dynamic overlays: the goal was to recreate a real IPTV-like heterogeneous scenario with home users enjoying the same stream and cooperating via P2P. IPTV needs bandwidth and computational resources that single peers often struggle to provide.
