摘　　要：由于目前NAT大多采用传统网络地址转换,所以位于Internet上的客户机无法主动访问位于NAT后面的内部网络服务器。文章简单介绍了NATT协议,提出了一种利用NATT协议实现NAT穿越的通信方法,分析了该方法的实现过程,并进行了性能测试。试验结果表明,该方法不会引起任何通信性能的下降。The conventional type of Network Address Translator（NAT） is commonly used nowadays. This leads the problem that the servers accessed to the Internet can not initiate communication from the external nodes to the internal nodes located behind a NAT. This paper introduces the NATY protocol, puts forward a method of NAT traverse by using NATT protocol, analyses the realization process and its performance test. The results show that the method will not cause the degradation of communication performance.
