This page summarizes the release planning for ns-3.28. The ns-3 release process is listed here and here.

Release status

ns-3.28 is undergoing initial planning (for maintainers to set the goals).

Release goals

Broad goals

Of course, resolving all 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.

  • Review and merge all of the summer project code (GSoC and SOCIS) (various project mentors)


  • PCF support (Sebastien Deronne)

Python bindings

Further automate the generation of bindings using CastXML, as discussed here: https://www.nsnam.org/bugzilla/show_bug.cgi?id=2451#c22


Feature level:

  • Revise and merge pacing at TCP layer
  • Revise and merge TCP LP
  • Cwnd Event
  • 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.

Bug Fixes:

  • Some of them in some order... I still haven't an exact plan.

Traffic control

Stefano Avallone mentioned the following plans.

  • introduce other qdiscs: fifo, prio and token bucket (from GSoC)
  • 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


  • Bug 2413 - Changes in the UAN module to support NS-3 IP stack (patch submitted, pending final review)
  • Bug 2805 - RFC6775-Neighbor Discovery Optimization for IPv6 (waiting for Tommaso recommendations)
