本文对于P2P路由模型NetShot的性能进行分析和测定。在基于对等网络（P2P）方式的Netshot路由模型的基本构架下，选用不同的方式来组织网络中结点，形成不同的具体形态，然后对这些网络结构中节点的加入、删除、消息通讯等一系列基本操作的开销进行推导并进行模拟验证-This article NetShot model for P2P routing performance analysis and measurement. Based peer-to-peer (P2P) routing model approach Netshot the basic fr a mework, the choice of different ways to organize network nodes to form different specific patterns, and then the structure of these networks by adding nodes, delete, message communication a series of basic operations, such as overhead for derivation and simulation
