Design and implementation of a Remote Information Transmission System Between Private IP Based on P2P

Aiming at the network environment and safe performance, a scheme of P2P-based transmission is proposed in this paper, mainly to solve the failure data transfer between remote computers.The authors adopt the protocol of STUN to detect the type of NAT and to pass through NAT.Demonstration test shows that the system has high performance in failure-file transmission between remote hosts among different NATs, better performance such as high-speed, security and reliability.
