Peer-to-peer (P2P) video streaming applications are widely popular, e.g. PPstream and PPlive, because of higher transmission speed and data availability. A fact of P2P streaming is that different peers have different (asymmetric) capabilities for resource sharing, and thus, some asymmetric P2P (A-P2P) topology and membership management schemes should be adopted among P2P nodes having heterogeneous computing and communicating capabilities. Our research focuses on designing a novel A-P2P streaming architecture with a dedicated codec scheme that applies multiple description features into the scalable extension of H.264/AVC, which is adaptive and error-robust enough to tackle challenges in the A-P2P network environment. In the streaming architecture, our proposed device-aware P2P topology management is responsible for constructing a hierarchical membership-tree based on the capacity of upstream bandwidth and round-trip time. In addition, the buffer-aware scheduling scheme is able to determine whether the peer needs to reconnect to a proper source provider or not, based on the buffer status. In our experiments, corresponding performances, e.g. average peer-join time and average peak signal-to-noise ratio, were measured and demonstrated.
