Abstract
The principle of NAT and the impact of NAT on P2P are discussed.To realize peer-to-peer communication,a solution of UDP Hole Punching is used to establish UDP connections between hosts which behind different NATs.Because UDP is a connectionless protocol,the address mapping within the NAT is dynamic.In order to maintain the dynamic address mapping within the NAT,a self-adaptive algorithm is proposed.
