The authors study and analyze segment transmission scheduling algorithms in swarm-based Peer-To-Peer (P2P) streaming systems. These scheduling algorithms are responsible for coordinating the streaming of video data from multiple senders to a receiver in each streaming session. Although scheduling algorithms directly impact the user-perceived visual quality in streaming sessions, they have not been rigorously analyzed in the literature. In this paper, the authors first conduct an extensive experimental study to evaluate various scheduling algorithms on many PlanetLab nodes distributed all over the world.
