This paper reports a test bed aiming at studying burst contention resolution mechanisms in "Labelled" OBS networks together with a simulation tool that is designed to back up experiments. The test bed is composed of a Labelled OBS core node and a measurement arrangement for burst capture and analysis. Different components of the test bed are presented together with their measured characteristics. The simulation tool is presented with a preliminary simulation that compares the Labelled OBS scheme with the conventional BCP OBS scheme. The results show that the Labelled OBS scheme outperforms the conventional OBS scheme.
