A hierarchical push-pull scheme for peer-to-peer live streaming

In this paper, we propose a hierarchical push-pull scheme for peer-to-peer (P2P) live streaming. In our scheme, a control topology is used for membership management, and a multi-source multicast tree for data delivery. The control topology facilitates peers to locate multiple sources for forwarding media content, and the multi-source multicast tree makes the system adaptive to node churn and packet loss. Simulation results show that our proposed method is significantly better than BT-Like systems.
