Introduction to Delay & Disruption Tolerant Networking (DTN)

DTN is the key internet engineering technology needed for interplanetary networking. DTN is actually a suite of experimental protocols developed by members of the Delay & Disruption Tolerant Networking Research Group (which operates under the aegis of the Internet Research Task Force) as Requests for Comment (RFC’s) administered by the Internet Engineering Task Force (IETF).

If you are not all that familiar with networking technology, follow the link below to a CNET News video explaining DTN basics. Thanks to our friends at the Cal Tech Jet Propulsion Laboratory for the explanatory animations.
