[Ns-developers] Ns-3.2 Release Candidate 4 Posted

[craigdo@ee.washington.edu]

Hi all,

Release candidate number four for ns-3.2 is available at the below location:

http://www.nsnam.org/releases/ns-3.2-RC4.tar.bz2

This is a release candidate, which means that we believe this version of
ns-3.2 is ready for release, but we want to make absolutely sure that
nothing has snuck in that could cause serious problems.  We would appreciate
it if you all could find time to look at this candidate with an eye to
finding problems before we call it "golden."  If you have contributed code
to this release candidate, please test it extensively.

Please see this "getting started" page if you are new to ns-3:

Supported platforms
-------------------

ns-3 is regularly tested on the following platforms:
  - linux x86 gcc 4.2, 4.1, and, 3.4.6.
  - linux x86_64 gcc 4.1.3, 4.2.1, 3.4.6
  - MacOS X ppc and x86
  - cygwin gcc 3.4.4 (debug only)

Known issues
------------

ns-3 is known to fail on the following platforms:
  - gcc 3.3 and earlier
  - optimized builds on gcc 3.4.4 and 3.4.5
  - optimized builds on linux x86 gcc 4.0.x
  - optimized builds on Ubuntu 8.10 alpha 5 x86 gcc 4.3.2
  - MinGW

New user-visible features
-------------------------
  a) Learning bridge (IEEE 802.1D)
    It is now possible to bridge together multiple layer 2 devices to
    create larger layer 2 networks. The Wifi and Csma models support
    this new mode of operation. (contributed by Gustavo Carneiro)

  b) Python bindings
    It is now possible to write simulation scripts in python using our 
    python bindings (contributed by Gustavo Carneiro).

  c) Real-time simulator
    It is now possible to run simulations synchronized on the real-world
    wall-clock time (contributed by Craig Dowell).

  d) Network Simulation Cradle
    It is now possible to use the Network Simulation Cradle 
    (http://www.wand.net.nz/~stj2/nsc/) in ns-3 and run simulations 
    using various versions of kernel TCP network stacks. (contributed
    by Florian Westphal as part of his Google Summer of Code work)

  e) A statistics framework
    Joseph Kopena contributed a statistics framework which can be used
    keep track of simulation data in persistent storage across multiple 
    runs (database and ascii file backends are available).
