Скачать или смотреть Lab: Introduction to the NASA Delay/Disruption Tolerant Networking Development Kit (2.1)

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).

The lab video in this section describe how to install a virtual environment that can run multiple independent ION nodes and impose connectivity constraints, bandwidth constrains, and transmission latencies on communication links connecting them.

This video series also demonstrates some of ION’s capabilities by running a simple emulation scenario. As hands-on exercises in configuring ION, videos in this section go through changing an ION convergence layer and adding a new node into an existing scenario with the configuration changes needed to add it to the network.
