🛰️ NASA/JPL Interplanetary Overlay Network (ION)

What is ION?

The NASA’s Interplanetary Overlay Network (ION) is an implementation of Delay/Disruption Tolerant Networking (DTN).

DTN is a digital communication networking technology that enables data to be conveyed reliably among communicating entities when roundtrip times may be highly variable and/or very long. Data transmission is done automatically and reliably even if one or more of the network links in the end-to-end path between those entities is subject to very long signal propagation latency and/or prolonged intervals of unavailability.

ION DTN is suitable to both planetary and interplanetary environments succeptible to communication delay and disruption.

Quick Start

1. Linux, MacOS or Solaris To build and install the entire ION system on a Linux, OS/X, or Solaris platform, cd into ion-open-source and enter three commands:

$ ./configure (If configure is not present run: "autoreconf -fi" first)
$ make
$ sudo make install

NOTE: if you want to set overriding compile-time switches for a build, the place to do this is in the ./configure command. For details,

$ ./configure -h

2. Android

To build ION for `Android`, cd into ion-open-source/arch-android and see the instructions in the `README.bionic` text file.

3. RTEMS

To build ION for `RTEMS`, cd into ion-open-source/arch-rtems and see the instructions in the README text file.

4. Windows

To build ION for `Windows`, see the instructions in the "Building ION from source on Windows.pdf" document.

5. ARM-based AT91SAM9G20 board

To build ION for the `ARM-based AT91SAM9G20 board`, cd into ion-open-source/arch-uClibc and see the instructions in the "ARM build.pdf" file. 

6. Build individual ION packages

It's also possible to build the individual packages of ION, using platform-specific Makefiles in the package subdirectories.  If you choose this option, be aware of the dependencies among the packages:

• The ici package must be built (make and make install) before any other package.

• The bp package is dependent on dgr and "ltp" and bssp as well as ici.

• The cfdp, ams, bss, and dtpc packages are dependent on bp.

• The restart package is dependent on cfdp, bp, ltp, and ici.

Also, be aware that these Makefiles install everything into subdirectories of /usr/local. To override this behavior, change the value of OPT in the top-level Makefile of each package.

Additional details are provided in the README.txt files in the root directories of some of the subsystems.

Note that all Makefiles are for gmake; on a freebsd platform, be sure to install gmake before trying to build ION.

• Tutorials, applications of Artificial Intelligence and IoT, and further details on ION capabilities can be found on the Wiki pages.

• Videos and documents and links to videos of the Interplanetary Overlay Network course can be found on the NASA website.
