Monday, February 27, 2017 @ 05:02 PM  posted by tomh

ns-3 is participating in GSoC 2017! We were happy to learn today that we will be participating in the 2017 Google Summer of Code. This program is a great opportunity for students to learn a bit about software engineering and open source projects, and for our project community to grow. Interested students are encouraged to interact with the project through the main project mailing list,, and to review our wiki. Students will have until April 3 to develop a project proposal and submit it to Google.

ns-3 accepted to ESA Summer of Code in Space (SOCIS) program

Friday, April 22, 2016 @ 05:04 PM  posted by tomh

The ns-3 project has been selected to participate in the 2016 edition of the European Space Agency (ESA) Summer of Code in Space (SOCIS) program. This marks the fourth consecutive year that ns-3 has been selected. SOCIS aims at offering student developers stipends to write code for various space-related open source software projects. Through SOCIS, accepted student applicants are paired with a mentor or mentors from the participating projects, thus gaining exposure to real-world software development scenarios. In turn, the participating projects are able to bring in new developers. The students eligibility is explained in the program website. However, the most important part is that they must be studying in an institution in one of the ESA Member States. Note that the eligibility requirement is about the institution, not about the student nationality.

Our ideas webpage is at The application deadline is May 15. More informations about SOCIS can be found on the SOCIS website.


ns-3.25 released

Thursday, March 24, 2016 @ 07:03 AM  posted by tomh

ns-3.25 was released on 24 March 2016 and features the following significant changes.

  • A new traffic control framework, inspired by the Linux traffic control subsystem, has been introduced to allow experimentation with Internet-aware active queue management (AQM) techniques, packet filtering, and policing. The existing network device queues were reworked, a Linux-like pfifo_fast queuing discipline was added, and existing AQM queue models (CoDel, RED) were ported to the new framework. The RED queue model was extended to support Adaptive RED.
  • The Wi-Fi module adds additional support for 802.11n and 802.11ac modes, including better support for larger channel widths and multiple spatial streams (MIMO), and a simplified helper API for MPDU and MSDU aggregation. Two adaptive rate controls for 802.11n/ac, Ideal and MinstrelHt, have been added. Finally, backward compatibility between 802.11g access points and 802.11b stations, and between 802.11n/ac and legacy stations, has been added.
  • The Internet module features a refactored TCP model to better support testing and to support modular congestion control classes. A RIPv2 routing protocol implementation was also added to the Internet module.

Finally, the release includes numerous bug fixes and small improvements, listed in the RELEASE_NOTES.
