摘要： 对等网络正在成为网络应用研究的一个新的热点，负载平衡技术是其中的一个重要问题。该文提出了一种基于局部负载扩散思想的对等网络负载平衡算法，对相应的负载评估标准、负载分散原则等内容进行了详细描述，最后给出了仿真试验结果。试验数据表明，该算法具有较低的系统开销、较小的响应延迟，减少了系统抖动现象的产生。

Abstract: P2P network is a new hotspot in network application research. Load balancing is one of its important problems. In this paper, a P2P network load-balancing algorithm based on local load diffusing idea is put forward. And the corresponding load evaluating standard and load diffusing principle are described in detail. The simulation result is presented finally. The experimentation data indicate that this algorithm has low overhead and minor latency. It can decrease thrashing effectively
