The Event Dispatcher is an integral component of the Digital Network
   Architecture that processes events generated by entities in the network.
   Each component layer architecture of the Phase V DNA architecture, such
   as Routing, NSP, and OSI Transport, may define certain occurrences,
   actions, transitions, or conditions as events that are reported and may
   be logged to assist network or system management.  The Event Dispatcher
   module allows these conditions to be logged and monitored to allow a
   system manager to view the state of the network.

   The hierarchical relationship of the entities that constitute the Event
   Dispatcher module are:

           Event Dispatcher
             Outbound Stream
             Relay
               Logging
             Sink
               Inbound Stream

   The Event Dispatcher entity is the top-level entity in the hierarchy of
   entities belonging to the Event Dispatcher module.
