The ns-3 Consortium will offer two days of user training on May 5-6, 2014 in Atlanta GA as part of its annual meeting, immediately preceding the Workshop on ns-3 on May 7. The two days of training, taught by several ns-3 maintainers, will be organized around the basic simulator on Monday and more advanced topics and extensions on Tuesday. A portion of each day will be reserved for interactive Q&A and guidance from the instructors, allowing deeper treatment of topics of particular interest. Additional details are available here and registration can be made here.
