摘要:
针对目前常用的几种NAT穿越技术存在的需要改变网络环境、不支持Symmetric NAT与TCP的穿越、延时、丢包等问题，在对P2P网络环境下NAT穿越原理认真分析的基础上，以穿越原理为基点，对目前NAT穿越技术存在的问题进行了研究。给出了‘采用端口预测穿越NAT的新方案爷，该新方案在不需要改变现有网络设备的情况下实现了TCP对各种NAT的穿越，减少了延时和丢包等NAT穿越常见的问题。通过大量的实验表明该新方案更适合于对网络安全需求更高而使用对称型NAT的企业。
Abstract:
Due to several problems in the common technology of the NAT traversal at present,such as the need of changing the environ-ment,non-supporting the Symmetric NAT and TCP traversal,delaying,the lost of data and so on,after carefully analyzing the theory of the NAT traversal in P2P,based on the traversing theory,studied the appearing problems of the NAT traversal,then give a new method of using pot to predict the NAT traversal. This new method achieves the way of TCP crossing all kinds of NAT in no need of changing the original equipment of the Internet,which reduced the common problems in the field of NAT traversal such as delaying and the lost of da-ta. Some experiments which has been verified present that the method can adapt to the enterprises which have higher requirement of net-work security and using a class of symmetry NAT.
