Abstract

The present paper introduces the Proxy Data Transfer system, which enables file transfer applications to work over long delays and leaky or frequently disconnecting networks (referred to hereinafter as a "challenged environment"), in which traditional end-to-end communication does not work well. An important feature is that the satellite link is applied to the control channel with a low data rate in order to achieve sustainability over a very large area. We developed a prototype and conducted an experiment using the Japanese engineering testing satellite "KIKU no.8" in May of 2008. An experiment using KIKU no.8 will be described and a live demonstration in an emulated network environment will be given at CHANTS2008.
