Research on NAT Traversal Problem in Peer-to-Peer

Due to several problems in the common technology of the NAT traversal at present,such as the need of changing the environment,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 data. Some experiments which has been verified present that the method can adapt to the enterprises which have higher requirement of network security and using a class of symmetry NAT.
