摘要： 传统网络消息传播基于存储转发路由机制，网络节点对于网络消息不进行任何处理，网络编码理论允许节点对传播的信息进行编码处理。基于此，利用网络编码数据包能携带更多网络信息的特点，提出一种对等网络环境下的互惠资源共享方法，保证对等网络资源共享的高可靠性和鲁棒性，并通过仿真实验加以实现。仿真实验结果表明，网络编码互惠资源共享方法能够提高对等网络资源共享服务的整体下载效率。

Abstract: Current network message transmission is based on store and forward mechanism. The network node does not process any messages. Network coding theory allows nodes coding and transmitting messages. This paper uses character of network coding package carrying more information to design reciprocal P2P network resource sharing method, which achieves reliability and robustness of P2P resource sharing. Through simulation experiment to evaluate the performance of P2P resource sharing system. Simulation experimental results show that network coding reciprocal resource sharing method makes P2P resource sharing application scalable and efficient.

Key words: Peer-to-Peer(P2P) network, network coding, resource sharing, linear coding, coding vector
