本文简要介绍了NAT(Network Address Translator)技术的原理及其在当前网络环境中的应用,分析了当前网络环境中广泛存在的NAT设备对P2P(Peer-to-Peer)通信的影响.阐述了包括ALG(ApplicationlayerGateway)、代理(proxy)R术及UDP打洞(UDPHole Punching)技术在内的多种NAT穿越技术,并在深入研究STUN协议及分析对比多种穿越技术的基础上提出了一种新的NAT穿越方案.使得NAT后的主机基本实现了在各种类型NAT下的成功穿越.

The theory and the application of the NAT's technology in the present network environment is t introduced briefly in this text, and the influence of the NAT devices on P2P (Peer-to-Peer) communications is also analyzed. NAT-traversal technologies are expatiated such as ALG, Proxy, and UDP hole punching, and STUN protocol is studied deeply, then a new scheme based STUN protocol and the analysis of these technologies is advanced, which makes hosts located behind N A Ts basically realize the traversal in varieties ofsituations successfttUy.
