[Ns-developers] ns-3.3 Release Candidate 3 Posted

[craigdo@ee.washington.edu]

Hi All,

I'm pleased to announce that release candidate number three for ns-3.3 is
immediately available at the below location:
http://www.nsnam.org/releases/ns-3.3-RC3.tar.bz2

This is a release candidate, which means that we believe this version of
ns-3.3 is close to ready for release, but we want to make 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."

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

New user-visible features in ns-3.3
-----------------------------------
  a) Emulated Net Device

     A new net device has been added as enabling technology for ns-3 
     emulation scenarios.  See src/devices/emu and 
     examples/emu-udp-echo.cc for details.  A new manual chapter on 
     emulation is now available as well.

  b) ICMP Support
     Support for several ICMP messages has been added to ns-3.  See
     src/internet-stack/icmpv4.h for details.

  c) IPv6 Address Support
     New classes to support IPv6 addresses has been added to the system.
     This is enabling technology for fuller IPv6 support scheduled for 
     ns-3.4.

API changes from ns-3.2
-----------------------
API changes for this release are documented in the file CHANGES.html

Known Issues
------------

A number of bugs have been fixed in this release, but some known bugs do
remain:

A late breaking regression test failure has been observed running
test-csma-ping in a 32-bit Linux version 2.6.20-1.2320.fc5, gcc version
4.1.1, with Intel(R) Pentium(R) 4 CPU 1400MHz.  The same error has been seen
on Cygwin 1.5.25-15, gcc version 3.4.4 (cygming special, gdc 0.12, using dmd
0.125).  This is related to a possible rounding error and is currently being
investigated.
 
For new users, it is important to note that the tutorial (in the
doc/directory) is inconsistent with respect to wifi phy changes recently
implemented.

See the bug tracker (http://www.nsnam.org/bugzilla/) for other known
problems (P1 bugs against ns-3-dev are considered blockers for the ns-3.3
release).

Please do not hesitate to file new bugs if you uncover problems; and please
test everything in sight.

Regards,

-- Craig
