A P2P Communication Model for IPv4/IPv6 Hybrid Network

We propose a P2P based communication model to resolve the inter-communication problem among the IPv4 and IPv6 terminals in large scale system. Our model well captures the traversing requirement of such hybrid network and achieves a balanced load through the networks. In addition, the model is highly adaptable to network topology changes and is able to support mobile terminals communication. We present the routing mechanism based on a route locality and searching algorithm built on Distributed Hash Table (DHT). The terminals form a flexible Overlay Network where each device has a unique Peer ID. They serve as a ¡ skeleton¡ of the network and distributedly store the route information and the mapping between IP addresses and Peer IDs. Our method provides both a seamless communication for the current hybrid network and a painless switching from IPv4 to IPv6.
