The ns-3.4 Release

This page summarizes the ongoing release planning for the Fourth stable release of ns-3.

ns-3-dev is scheduled to enter the open phase for ns-3.4 on December 17, 2009. Until then, checkins of new features are forbidden.

The Release Manager

The release manager is Raj Bhattacharjea.

The ns-3.4 Release Schedule

ns-3 releases are based on date-driven schedules as opposed to feature-driven schedules. We decide on an approximate release date and then the release manager works backward to define windows during which time certain activites related to the release can happen. This was done for ns-3.3 and the important milestones for that release can be found here.

Candidates for Merge into ns-3.4

As you can see in the Roadmap, we have identified several candidates for inclusion in ns-3.4. As time passes and details become more evident, more status regarding the progress of these new features will be added.

Random Number Generator and RandomVariable Changes.

• Removal of static APIs for drawing random numbers
• New seeding API separates seeding functionality into a separate class
• Exposure of the run number and global seed to the attributes/config system
• Review is converging
