Abstract :
Demand for users accessing networks anytime and from anywhere has been increasing in the forthcoming advent of heterogeneous society which is the convergence of the existing networks. The existing NAT technologies have some flaws and canpsilat meet the requirements in such environment. In this paper, we present a distributed NAT traversal mechanism suitable for the IP heterogeneous network. The mechanism adopts a dynamic address mapping method in the gateways to solve the NAT traversal problem and does not use any extra servers by means of using P2P storage technology to solve the "single point bottleneck" problem. The mechanism makes the less modifications in the gateways and does not add any functions in the client terminals. We have implemented and evaluated a trial system, and the results show that there is almost no performance degradation.
