ns-3 is excited to have been selected to the 2018 edition of 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 March 27 to develop a project proposal and submit it to Google.

The Workshop on ns-3 (WNS3) is a one and one-half day workshop to be held on June 13-14, 2018, hosted by the National Institute of Technology Karnataka (NITK) Surathkal, Mangalore, India. The objective of the workshop is to gather ns-3 users and developers, together with networking simulation practitioners and users, and developers of other network simulation tools, to discuss the ns-3 simulator and related activities. The Call for Papers is published on a separate page, and an annual meeting flyer is available.

ns-3.27 was released on 12 October 2017 and features the following significant changes.

  • Carrier Aggregation support was added to the LTE module.
  • Native TCP models have been extended to include SACK and LEDBAT models.
  • The Wi-Fi module was extended for partial 802.11ax High Efficiency (HE) support, and a new Robust Rate Adaptation Algorithm (RRPAA) rate control has been added.
  • The traffic-control module has been reworked, with new support for gathering detailed statistics about the operations of a queue disc, a new multi-queue aware queue disc modelled after the mq qdisc in Linux, and the ability to explicitly trace queue sojourn time.

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

The ns-3 project has been selected to participate in the 2017 edition of the European Space Agency (ESA) Summer of Code in Space (SOCIS) program. This marks the fifth consecutive year that ns-3 has been selected. Our 2017 student is Pasquale Imputato, a PhD student in Information Technology and Electrical Engineering at University of Naples Federico II. Pasquale aims to improve the emulation capabilities of the simulator by the introduction of netmap in ns-3. netmap is a fast packet processing technique that bypasses the host networking stack and allows direct network device access. More information on Pasquale’s project is found on his wiki page.
