摘 要: 对等网技术的广泛使用为网络用户共享资源提供方便快捷的途径,但由于网络地址转换NAT的存在,使网络环境变得复杂,阻碍了P2P在各种网络环境下的使用.介绍了P2P的基本概念及NAT的技术原理,阐述了P2P在线视频通讯系统中UDP通信穿越NAT的原理及其具体实现方案. The wide application of P2P network technology provides a quick and easy way to share network resources.But the NAT(Network Address Translation) prevent so many computers in Internet to access those computers behind NAT actively.So the P2P applications must solve the problem of bidirectional communication across NAT.This paper introduces the principle of P2P and NAT,and describes the realization of the UDP communication across NAT in P2P applications based on the online video communication system in P2P network designed by author.
