This page summarizes the ongoing release planning for ns-3.9. Josh Pelkey and Tom Henderson are acting release managers.

Tentative Release Schedule

  1. May 3 -- ns-3.8 posted; ns-3.9 Open phase begins
  2. June 16 -- Deadline for proposing major new features to be merged; begin the phase of small feature development and bug fixing
  3. June 25 -- Deadline for merge of major features identified on the release page
  4. July 20 -- Small feature development and bug fixing ends; Maintenance phase begins
  5. August 6 -- Maintenance phase ends, code freeze phase begins; only P1 critical blockers and documentation

beyond this date

  1. August 11 -- First release candidate (ns-3.9 RC1)
  2. August 16 -- Documentation and code freeze (manuals/tutorials/Doxygen) (ns-3.9 RC2)
  3. August 20 -- Currently planned ns-3.9 release date, ns-3.10 phase begins

Release status

Final Checklist

  • resolve mobility model bug
  • gcc-3.4
  • test the bugs that Craig listed yesterday (Tom)
  • update wiki page on which features go with which operating systems
  • fix PeekData instance that craig missed

    • enable-sudo
    • enable-static
    • sqlite
    • xml

  • Generic sequence number class (issue 385)
  • Issue 943: Add SO_BROADCAST socket option

Wait for ns-3.10:

  • NetAnim trace hooks for wireless (patch in preparation)

Bug fixing list

Current status of ns-3 bugs for ns-3.9.

  • NSC:
    • 980 NSC compilation fails on 32-bit machines
  • WiFi:
    • 958 WiFi defaults http://www.nsnam.org/bugzilla/show_bug.cgi?id=958
    • 952 WifiMacQueue sender queue drops every 120 seconds of simulation, apparently for no particular reason
    • 968 Beacon generation does not use CSMA deferral
    • 941 Wifi Dcf attributes not reachable through configuration namespace
    • 555 DCF immediate access: http://www.nsnam.org/bugzilla/show_bug.cgi?id=555 <--- Wont fix for ns-3.9
    • 934 assertion failure in dcfmanager.h on heavy load
    • 842 BlockAck crasher
    • 799 Interference helper is too slow
  • Point to Point:
    • 948 PointToPointNetDevice does not keep track of destination addresses
    • 949 Node::NonPromiscReceiveFromDevice reports a meaningless destination address to user callbacks
    • 950 PointToPointNetDevice says promisc support is not implemented but it is
  • InternetStack
    • 969 No SocketList is present in UdpL4Protocol class
    • 942 ipv4-raw-socket-impl should listen more than one protocol <-- plan to mark invalid
    • 911 IPv4 multicast forwarding not going to all output interfaces in route
  • Other
    • 930 examples/topology-read/topology-example-sim.cc uses variable length array
    • 970 move UAN over to new directory structure

Documentation

Non-blockers, probably rolling into ns-3.10 release cycle

Features that may slip

The following features are slipping to ns-3.10 or later:

  • VANET mobility model (no reviews)
  • TCP Vegas (blocked by lack of progress on TCP congestion control architecture)
  • Chord/DHT (authors are planning to revise code based on comments)
  • app store and build system refactoring
  • remove ./waf --regression
