Teredo is the only one tunnel mechanism designed for NAT users. However, Teredo does not support symmetric NAT users and cannot allocate stable IPv6 addresses for the users, and also has security problems. Based on client-server tunnel mode and servers' statefule characteristic, a new tunnel mechanism named Silkroad is proposed to resolve Teredo's problems. The mechanism makes use of tunnel servers, which assign IPv6 addresses to users and then act as relays to transmit the packets between NAT users and IPv6 networks. In addition, an adaptive communication optimization scheme is presented to reduce the time cost of communication between two clients. Silkroad supports all types of NAT users to connect with IPv6 networks, can assign stable IPv6 addresses to the users and has high security.
