During the last three academic years, between 2014-2017 the Laboratory of our faculty which is involved in Free Software Testing was the scene of a set of experiments în Network Simulations. The goal was to provide a set of training sessions to the students of the F.R. program of The Faculty of Sciences (F.R. means students learning from the distance). Three kinds of software was involved in our test and one had succeeded in being selected as the software support of the Networks Laboratory: CORE. The papers is illustrating the use of CORE în a small network simulation, one of those who will be presented in a book by a romanian editor.
