| 摘 要： | 本文通过对NAT的原理分析，针对在两台不同NAT设备后两个内网主机之间相互通信的问题提出了解决的基本思想，分析了UDP穿透NAT的基本原理，给出了简单又健壮性很好的UDP Hole Punching技术以实现NAT的穿越，并在最后提出一种NAT端口映射保持的自适应算法，解决了NAT中动态端口地址映射的保持问题。

| Abstract: | The principle of NAT and the impact of NAT on P2P are discussed. To realize peer-to-peer communication, the paper uses a solution of UDP Hole Punching to establish UDP connections between hosts which behind different NATs. Because UDP is a connectionless protocol, the address mapping within the NAT is dynamic. In order to maintain the dynamic address mapping within the NAT, a self-adaptive algorithm is proposed. |
