Open Source VxWorks Networking Software

11/21/2025 * Official distribution sites for ION and ION-core have moved to GitHub: https://github.com/nasa-jpl/ION-DTN https://github.com/nasa-jpl/ion-core * ION documentation: https://ion-dtn.readthedocs.io/ Download link for new releases (after ION 4.1.2) is posted below. Please report all issues to GitHub. Submissions to this site will not be monitored. ============================= ION development is managed by the Jet Propulsion Lab. The Interplanetary Overlay Network (ION) software distribution implements Delay-Tolerant Networking (DTN) architecture, as described in Internet RFC 9171. It is designed for use in embedded environments, including spacecraft flight computers and ground systems. ION 4.1.3s is the last version to provide both BPv7 and v6. Starting ION 4.1.4, only BPv7 code will be available.

TCNOpen is an open source initiative which the partner railway industries created with the aim to build in collaboration some key parts of new or upcoming railway standards, commonly known under the name TCN. TCN (Train Communication Network) is a series of international standards (IEC61375) developed by Working Group 43 of the IEC (International Electrotechnical Commission), specifying a communication system for the data communication within and between vehicles of a train. It is currently in use on many thousands of trains in the world in order to allow electronic devices to exchange information while operating aboard the same train. TCNOpen follows the Open Source scheme, as the software is jointly developed by participating companies, according to their role, so as to achieve cheaper, quicker and better quality results.

openPOWERLINK is an Open Source Industrial Ethernet stack for communication in hard real-time. It can be operated as both, Managing Node (master) and Controlled Node (slave). With version 2.0, the source code has been cleanly split into an application-oriented user library and a time-critical stack driver. The latter may be moved to a dedicated communication processor or into a kernel module to deliver enhanced performance while still keeping the API in user space. A full documentation of the stack is available on the web site: http://openpowerlink.sourceforge.net The following page can be used to report a security vulnerability: https://sourceforge.net/p/openpowerlink/discussion/

yaSSL, or yet another SSL, is an embedded ssl library for programmers building security functionality into their applications and devices. yaSSL is highly portable, and runs on standard as well as embedded platforms(QNX, ThreadX, VxWorks, Tron) yaSSL is still available but no longer being developed. Current development on the same project continues under wolfSSL. Visit yaSSL Home above for the latest stable release.

This project contains an example Code of an Ethernet Network Driver for the Sercos III network which will communicate with help of the unified communication channel. This driver connects the UC Channel (CoSeMa API) to e. g. a VxWorks TCP/IP stack.
