Delay and Disruption Tolerant Networking (DTN)

Learn more about the Interplanetary Internet by visiting our Zotero Library and watching the
IPNSIG Academy keynotes listed on the Events page.

Check out this 25-year retrospective on the development of Delay-Tolerant Networking (DTN). 

IPNSIG looks 100 years into the future to explore how the interplanetary networking infrastructure will support exploration and even commercialization of interplanetary space. IPNSIG strives to create a shared vision - a technological roadmap - for the interplanetary internet.

We invite you to view NASA's DTN Flight Validation Experiment video for a quick overview of the challenges of communicating in space and the essential characteristics of a DTN communication system.

Vint Cerf describes the events leading up to the creation of the Interplanetary Internet.
