This page summarizes the ongoing release planning for ns-3.19. The ns-3 release process is listed here and here.

The release managers are Tom Henderson and [bpswenson3@gatech.edu Brian Swenson]. Contact them if you would like to coordinate your software inclusion with this release.

Release schedule

ns-3.19 is scheduled for December 18, 2013. The first release candidate is due Friday December 13, 2013. Sunday Dec. 15.

Proposed supported platforms

Our primary platforms for this release are planned to be:

  • Fedora 19/20 (32/64 bit systems)
  • Ubuntu 13.10 (32/64 bit systems)
  • Ubuntu 12.04 LTS and 10.04 LTS (64 bit)
  • CentOS/RHEL 6.4 (64-bit)
  • Mac OS 10.8 Mountain Lion and 10.9 Mavericks (64 bit) with Xcode 5.0
  • FreeBSD 8.4, 9.2 (64 bit) using gcc and clang compilers


ns-3.19 will be packaged as a source tarball as before: ns-allinone-3.19.tar.bz2.

The tarball will contain:

  • pybindgen

where bake is used to fetch optional ns-3 components.

Release goals

This release will be mainly aimed at bug fixing and merging a few new features. After this release, we plan to take the next step at further modularizing the code.

We have merged our 2013 GSoC contributions in this release.
