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.
