//
// = 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.

  //   TAO Real-time Event Service; a simple UDP address server.
  //
  // = DESCRIPTION
  //   The EC is able to use multiple multicast groups to transmit its
  //   data, the is given control over the mapping between the Event
  //   (type,source) pair and the (ipaddr,port) pair using a
  //   AddrServer.
  //   This class implements a very simple server that simply maps the
  //   <type> component to the <ipaddr> and uses a fixed <port>,
  //   provided at initialization time.
