By

Views: 2,066A special thank you to Laura Chappell for contributing this profile for her Deep Space Networking challenges for the Delay/Disruption Tolerant Networking (DTN). You can read more about about DTN on the NASA web site here: https://www.nasa.gov/directorates/heo/scan/engineering/technology/disruption_tolerant_networking and on Wikipedia: https://en.wikipedia.org/wiki/Delay-tolerant_networking In November 2007, Scott Burleigh and Keith Scott released the “Bundle” Protocol Specification in RFC 5050.
