Existing approaches use peer-to-peer schemes to repair loss packets via peer-to-peer networks. However, they ignore coordinating peers in peer-to-peer networks, this can have an effect on chunk availability and control messages overhead. Fewer replicas can lead to lower availability and more replicas may waste space in low utility environment. So, coordinating peers to distribute peer’s loading is very important in peer-to-peer streaming systems. In this thesis, we propose a novel approach that considers load distribution in structured peer-to-peer networks and repairing loss packets in short lookup latency. Performance evaluation results show that our proposed method can achieve load sharing and increase chunk availability, shorten lookup latency with low control messages overhead for the whole peer-to-peer networks.
