摘　　要：互联网的技术发展,使得P2P技术逐渐成为被广为关注和使用的"通信传播"技术。但是,出于高安全性的考虑,绝大多数公私有网络边界上都安置了NAT/防火墙,这些设施的存在给P2P通信造成了很大的阻碍。针对这个问题,在对比分析现有的基于UDP协议的P2P通信数据包穿透NAT/防火墙的算法的同时,将阐述一种更具适应性的穿透算法,并在ACE(自适应通信环境)网络开发包的基础上尝试实现此算法。Due to the development of network technology. Peer-to-Peer（P2P） has been becoming one of the most popular technologies of network communication. For the sake of high level security,lots of firewalls or NATs are placed on the edge of private and public domain of network, which bring impenetrable difficulties to P2P communication. The existing NAT/FW traversal algorithm based on UDD protocol is analyzed,and a more well-adjusted algorithm of NAT/FW traversal based on ACE Toolkit is introduced and implemented.
