Delay/Disruption-Tolerant Networking: Flight test results from the international space station

The University of Colorado is working with NASA to extend Earth's internet into outer space and across the solar system. The new networking technology is called Disruption Tolerant Networking (DTN), and is being tested on the International Space Station. DTN will enable NASA and other space agencies around the world to better communicate with international fleets of spacecraft that will be used to explore the moon and Mars. This technology is evolving into an Interplanetary Internet. In this paper we describe the design and features of the DTN-on-ISS implementation as well as reporting initial results from the experimental deployment. 1,2
