+// = DESCRIPTION
+//   Simple implementations of the UDP Administration service.
+//   
+//   connects to a "remote" EC as a consumer, it also connects to the
+//   <local> EC as a supplier of events, this later EC is usually
+//   collocated.
+//   The QoS parameters for both connections must be provided by the
+//   user.
+//   To avoid infinite loops of events the Gateway descreases the TTL
+//   field of the events and will not deliver any events with TTL less
+//   than or equal to 0.
+//
+// = TODO
+//   The class makes an extra copy of the events, we need to
+//   investigate if closer collaboration with its collocated EC could
+//   be used to remove that copy.

+  //   (type,source) pair and the (ipaddr,port) pair using a
+  //   AddrServer.

+  //   <type> component to the <ipaddr> and uses a fixed <port>,
+  //   provided at initialization time.
