| 摘 要： | P2P技术通过改变人们经服务器中转交换文件的传统方式,达到了自由交换资源的目的。网络地址转换(NAT)技术在解决公网IP紧缺,确保网络安全方面起到重要作用,但同时带来阻隔不同子网内用户之间直接通信的问题。为此一系列穿越NAT实现P2P通信的方案孕育而生。文章介绍了一种能够在两个NAT设备主机间建立直接TCP连接的方法,称为NatTrav。并且模拟真实环境将之成功实现。

| Abstract: | Peer-to-Peer(P2P) networks have become increasingly popular.Controversy generated by P2P file-sharing programs and other useful and legitimate applications of P2P exist.Network Address Translation was introduced as a means to continue the Internet's growth despite rapid depletion of IPv4's 32-bit address range.A secondary funciton of NAT is to hide the network topology from an external entity.while NAT causes well-known difficulties for peer-to-peer(P2P) communication.This paper proposes approach called NatTrav to create TCP connection between two hosts behind typical NATs designed for small networks.We implemented successfully in simulating environment. |
