摘　　要：针对对等网络系统中处于局域网内节点很难与局域网外节点建立连接与通信的问题,研究设计了一种基于UDP协议穿透NAT设备的模型,并基于设计的模型进行了节点穿越常用NAT设备的仿真实验。仿真结果表明,常用NAT设备参数配置若符合一定的规范,对等网络中节点基于UDP协议采用打洞技术就容易实现对NATs设备的穿透。The issue that peers behind a LAN are difficult to set up communications with peers in other LANs in peer-to-peer networks and a kind of peer-to-peer mode of passing is presented through NATs based on UDP protocol. A series of simulation experiments are done based on designed model. These simulation experiments show peers in peer-to-peer system is easy to pass through NATs with hole punching technologies based UDP protocol.
