# 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 and More



* Tutorials, applications of Artificial Intelligence and IoT, and further details on ION capabilities can be found on the [Wiki](https://github.com/nasa-jpl/ION-DTN/wiki) pages.



* Videos and documents and links to videos of the Interplanetary Overlay Network course can be found on the [NASA](https://www.nasa.gov/directorates/heo/scan/engineering/technology/disruption_tolerant_networking_software_options_ion) website.
