Some of these messages are from the OMF Experiment Controller, which is interpreting your OEDL experiment description and sending corresponding commands to the resources. Other messages are from the resources themselves (either the VM nodes or the applications), reporting on configuration and command results.

    267267 2. From these 2 graphs, we can see that as the video content is downloaded by the modified !BitTorrent application on the leechers, the VLC players running on the same resources report a continuously increasing number of of frames being played. The relatively 'smooth' linear increase in these numbers indicate that the players never ran out of continuous frames to play. This demonstrate that the modified !BitTorrent application is suitable for video streaming.
