Lab: Base Scenario Delay/Disruption Tolerant Networking (2.4c)

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. One software option to implement DTN is NASA’s Interplanetary Overlay Network (ION).
This video describes and discusses the ION node configurations for the ‘base’ scenario used in the video Lab: Obtaining the NASA Delay/Disruption Tolerant Networking Development Kit (2.2). As a concrete example of modifying ION configurations, it then goes through the process required to change the configuration of a DTN convergence layer link between two DTN nodes from UDP to TCP.
