    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.  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.
