Abstract

During the transition from IPv4 to IPv6, it is necessary to provide IPv6 access service for IPv6 islands inside the native IPv4 network to access the native IPv6 network The existing IPv4/IPv6 transition methods make IPv6-relay gateways maintained by IPv6 service providers become potential communication bottlenecks In this paper, a new method PS6 is presented to reduce the reliance on these relay gateways by shifting the burden to edge gateways on each IPv6 island In this method, direct tunnels are set up between IPv6 islands, and a overlay network is maintained between edge gateways of IPv6 islands to propagate information of tunnel end points After describing the algorithm and overlay network design, we analyze the scalability of the algorithm The simulation results and theoretical analysis show that the proposed method is reliable and scalable.
