摘要
NAT设备的广泛使用限制了很多P2P应用软件的使用,能否顺利地穿透各种类型的NAT是P2P软件成功的重要因素。NAT设备很好地解决了IPv4的地址稀缺和网络安全等问题,因而被广泛应用。同时,也给P2P提出了新的难题,比如内网和外网使用2种不同的IP地址,而且很多NAT设备会过滤掉外部网络的IP包。如何在NAT环境中,实现P2P应用是学术界和工业界普遍关注的问题。
NAT did equipment＇s widespread restriction on use many P2P application software＇s use, whether penetrate each type NAT is the P2P software successful important attribute smoothly. The NAT equipment solved the IPv4 address to be scarce well and questions and so on network security, thus is widely applied. At the same time, also proposed to P2P the new difficult problem, for instance in the net and outside the net uses 2 kind of different IP addresses, moreover many NAT equipment can filter the exterior network the 1P package. How in the NAT environment, realizes the P2P application is the academic circle and the industrial world universal matter of concern.
