Delay/Disruption Tolerant Networking
Communicating from Earth to any spacecraft is a complex challenge, largely due to the extreme distances involved. When data are transmitted and received across thousands and even millions of miles, the delay and potential for disruption or data loss is significant. Delay/Disruption Tolerant Networking (DTN) is NASA’s solution to reliable internetworking for space missions. For previous missions from low-Earth orbit to deep space, NASA has used point-to-point (direct) or single relay links to com...
