    33 Component that runs on a console and is use to control the experiment.
     33The nodehandler is the central experiment controller. A central '''NodeHandler''' process communicates with '''NodeAgents''', one on each active node in the testbed.  The '''NodeHandler''' is hosted on one of the testbed's utility servers (typically called console).  Applications are loaded and executed by a '''NodeAgent''' on instructions from the '''NodeHandler'''.  These instructions will also include the initial property settings for the applications.
