Release and development schedule
ns-3.23 is planned for Wednesday May 6 2015 (the goal is to release this before the Workshop on ns-3 the following week). ns-3 makes roughly three releases per year (Dec/Jan, Apr/May, and Aug/Sept timeframes).
An initial release candidate is planned for Saturday May 1.
Packaging
ns-3.23 will be packaged as a source tarball as before: ns-allinone-3.23.tar.bz2.
The tarball will contain:
- Latest version of pybindgen
- Latest version of netanim
- ns-3.23
- bake
where bake is used to fetch optional ns-3 components, including DCE.
A patch from ns-3.22 to ns-3.23 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-3.23 release, we plan to support the following systems and compilers:
- OS X 10.10 Yosemite with latest Xcode (6.3)
- Ubuntu 14.04, 14.10, and 15.04
- Fedora 21
- Debian 7 (gcc-4.9)
- FreeBSD 10 (clang 3)
- CentOS 6.6 (gcc-4.4.7)
Testing repos
Some repositories, based on a recent copy of ns-3-dev, are available for testing specific features.
Mobility Service Interface
Note: inclusion of this code will slip to ns-3.24
Tiago Cerqueria has posted some code that uses Google Maps and Directions API to fetch waypoints for the ns-3 waypoint mobility model, corresponding to real-world routes provided by the service. There is a testing repository available for this code (the patchset in https://codereview.appspot.com/176430044/ is too large to download from Rietveld). To test, one must obtain an API key from Google, as described in the code review issue. One must also have installed GeographicLib, xerces-cpp, libcurl, and libdl.
hg clone http://code.nsnam.org/ns-3-dev cd ns-3-dev/src hg clone http://code.nsnam.org/tomh/mobility-service-interface cd mobility-service-interface mkdir conf # copy your API key to this conf directory as described here https://codereview.appspot.com/176430044/ cd ../../ ./waf configure ...
Python 3 support
Modifications to support Python 3 are available as part of a 2014 summer project, were planned for inclusion in this release cycle.
Note: This support will slip to ns-3.24 release cycle.
hg clone https://bitbucket.org/ssanturkar/ns-3-python-port/src
