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 was released on 21 August 2019.

Release goals

Note: This section is outdated; ns-3.30 has already been released with some of these goals met but not all.

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.

System-wide

• Finish the Python bindings scanning process using CastXML for MacOS (Tom Henderson, Ankit Deepak, Gustavo Carneiro)
  • https://www.nsnam.org/bugzilla/show_bug.cgi?id=2451#c22

• Make ns-3 compatible with Windows Visual Studio (Robert Ammon)
  • Ns-3_on_Visual_Studio

• Get to zero Doxygen warnings (Robert Ammon, Tom Henderson)
  • We are close; additional patches to merge (provided by Robert) are at: https://www.nsnam.org/bugzilla/show_bug.cgi?id=938

New features

• Review and merge remaining summer project code (GSoC and SOCIS) (various project mentors)
  • See this wiki page for links

• Other new features are listed on the tracker (some requiring reviews, and more work)
  • code review issues

TCP

Feature level:

• Westwood test suite

Performance:

• 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

Documentation:

• 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
