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.\n\nION DTN is suitable to both planetary and interplanetary environments succeptible to communication delay and disruption.\n\n## Quick Start\n\n**1. Linux, MacOS or Solaris**\n\tTo build and install the entire ION system on a `Linux, OS/X, or Solaris\nplatform`, cd into ion-open-source and enter three commands:\n\n````\n$ ./configure (If configure is not present run: \"autoreconf -fi\" first)\n$ make\n$ sudo make install\n````\n`NOTE`: if you want to set overriding compile-time switches for a build, \nthe place to do this is in the ./configure command.  For details,\n\n````\n$ ./configure -h\n````\n\n**2. Android**\n\n\tTo build ION for `Android`, cd into ion-open-source/arch-android and see the instructions in the `README.bionic` text file.\n\n**3. RTEMS**\n\n\tTo build ION for `RTEMS`, cd into ion-open-source/arch-rtems and see the instructions in the README text file.\n\n**4. Windows** \n\n\tTo build ION for `Windows`, see the instructions in the \"Building ION from source on Windows.pdf\" document.\n\n**5. ARM-based AT91SAM9G20 board**\n\n\tTo 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. \n\n**6. Build individual ION packages**\n\n\tIt'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:\n\n* The `ici` package must be built (`make` and `make install`) before any other package.\n\n* The `bp` package is dependent on `dgr` and \"ltp\" and `bssp` as well as `ici`.\n  \t\t\n* The `cfdp`, `ams`, `bss`, and `dtpc` packages are dependent on `bp`.\n\n* The `restart` package is dependent on `cfdp`, `bp`, `ltp`, and `ici`.\n\nAlso, be aware that these Makefiles install everything into subdirectories\nof /usr/local.  To override this behavior, change the value of OPT in the\ntop-level Makefile of each package.\n\nAdditional details are provided in the README.txt files in the root\ndirectories of some of the subsystems.\n\nNote that all Makefiles are for gmake; on a freebsd platform, be sure\nto install gmake before trying to build ION.\n\n## Tutorials and More\n\n* 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.\n\n* 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.\n\n* For details about changes regarding each ION release, please see the [Release Notes](./release-notes.txt)\n\n## Copyright and No Warranty Disclaimer\n\nThe software and/or related materials are provided \"AS-IS\" without\nwarranty of any kind including any warranties of performance or\nmerchantability or fitness for a particular use or purpose (as set\nforth in UCC 2312-2313) or for any purpose whatsoever, for the\nlicensed product, however used.\n\nIn no event shall caltech/jpl be liable for any damages and/or\ncosts, including but not limited to incidental or consequential\ndamages of any kind, including economic damage or injury to\nproperty and lost profits, regardless of whether Caltech/JPL shall\nbe advised, have reason to know, or in fact shall know of the\nPossibility.\n\nUser bears all risk relating to quality and performance of the\nsoftware and/or related materials.\n\n**Copyright 2002-2013, by the California Institute of Technology.
