This page summarizes the release planning for ns-3.21. The ns-3 release process is listed here and here.

The release manager is Tom Henderson.

Release schedule

ns-3.21 is planned for late August, 2014. New code should be ready for merge by roughly 1 August. An initial release candidate should be available by mid-August.

Packaging

ns-3.21 will be packaged as a source tarball as before: ns-allinone-3.21.tar.bz2.

The tarball will contain:

• Latest version of pybindgen
• Latest version of netanim
• ns-3.21
• bake

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

A patch from ns-3.20 to ns-3.21 will also be posted.

Release platforms

We usually try to keep pace with the latest popular versions of Linux, OS X, and FreeBSD. For the ns-3.21 release, we plan to support the following systems and compilers:

• OS X 10.9 Mavericks with Xcode 5.1
• Ubuntu 14.04 (gcc-4.8)
• Fedora 20 (gcc-4.8)
• Debian 7 (gcc-4.9)
• Ubuntu 10.04 LTS (gcc-4.4)
• Ubuntu 12.04 LTS (gcc-4.6)
• Centos 6.4 (gcc-4.4)
• FreeBSD 9.3 (clang 3.3)

New features

Pending new features:

• Self-Delimiting Numeric Values (https://codereview.appspot.com/97540043/)
  • Status: In final code review
• (enhancement) RttEstimator improvements. The RttEstimator is a class used by TCP to track round trip time measurements and state. There are several open issues:
  • Make RttEstimator available to other modules
  • move backoff management to TCP, align with RFC 6298
  • Make trace source of Tcp's RTO (and perhaps SRTT and RTTVAR) easier
• TCP Options support from SOCIS TCP project
• (enhancement) Add propagation delay capability to SimpleChannel (for testing purposes)
• CoDel queue support (from GSoC bufferbloat project)

WiFi-related:

• Wifi Sleep mode
• MPDU aggregation
• new VANET example

Additionally, selected features from the Current Development code reviews list will be included (to be determined).

Software maintenance issues

• Remove emu module from codebase
• Mesh test crashes for certain configurations
• Time arithmetic consistency
• Wstrict-overflow and gcc-4.9
