Delay/Disruption Tolerant Networking
Delay/Disruption Tolerant Networking (DTN) is a suite of standard protocols that uses information within the data stream to accomplish end-to-end data delivery through network nodes. A DTN architecture is a store-and-forward communications architecture in which source nodes send DTN bundles through a network to destination nodes.
DTN Overview
DTN Mission Resources
Explore various resources for supporting your mission with DTN.
Why should you use DTN on your mission? DTN can benefit all types of missions and is currently being used by payloads on the International Space Station, on lunar and deep space missions. In coordination with NASA’s Science Mission Directorate, the Space Communications and Navigation (SCaN) program is implementing the infrastructure necessary to support DTN for future missions. Helpful resources such as software options, information on standards, and other mission resources are available below.
