This page summarizes the release planning for ns-3.30. The ns-3 release process is listed here and here.

Release status

ns-3.30 is planned for late 2018.

Release goals

Of course, resolving confirmed issues in our tracker is a priority. Here are a few more things we'd like to accomplish this cycle, and the names of people who volunteer to work on the issue.


New features

  • Review and merge remaining summer project code (GSoC and SOCIS) (various project mentors)
  • Other new features are listed on the tracker (some requiring reviews, and more work)



Feature level:

  • Westwood test suite


  • Performance improvements, by replacing RFC algorithms with faster versions: do RFC + faster version in debug mode (checking for result equality), and disable RFC algorithms in release mode


  • Split TcpSocketBase in three different source files: one for input, one for output, other for the state machine. 3000+ lines to read are a non-starter for educational purpose.

- Document the missing features when comparing ns-3 with Linux TCP.

Traffic control

Stefano Avallone mentioned the following plans.

  • help Pasquale and Tommaso to merge the netmap netdevice (SOCIS)
  • if time permits, implement the Diffserv to IEEE 802.11 mapping as defined by draft-ietf-tsvwg-ieee-802-11-09
  • review and merge a few pending code reviews which implement other qdiscs (REM, BLUE, PI, PI2) and add ECN support to CoDel and PIE
