摘　　要：对P2P网络结构进行混合式拓扑设计,并采取网络编码策略,使节点在存储、转发的单一功能之上增加编/解码操作。仿真结果表明,该方法有效地提高了资源的下载速率和成功率,同时也增强了P2P内容分发系统的鲁棒性和安全性。This paper designed the P2P network structure and adopted the strategies of network coding based on the hybrid topology structure, then, the nodes would have the encoding and decoding operation except for the storage and forwarding function. The simulation results show that the download rate and success rate of resources are all greatly improved, and the robustness and security of the system is enhanced.

关 键 词：P2P 混合式拓扑 网络编码 内容分发
