Development Tools for Bidirectional Communication on Overlay Network

Abstract

Many development tools for P2P applications are proposed, but do not address a problem of connection between unconnectable nodes. The problem is that, IPv4 nodes and IPv6 nodes cannot be directly connected. We propose a development tool with ReverseLink and RelayLink. For example, with our tool, NATed node can connect other NATed node throught a IPv4 Relay node. Results from experiments show that our proposal make a structured overlay network with 10 NATed nodes and 10 IPv4 nodes. However, it takes 3 times as long as a normal overlay network does.
