Define helper classes to propagate events between ECs using either UDP or multicast. The architecture is a bit complicated and deserves some explanation: sending the events over UDP (or mcast) is easy, a Consumer (TAO_ECG_UDP_Sender) subscribes for a certain set of events, its push() method marshalls the event set into a CDR stream that is sent using an ACE_SOCK_Dgram. The subscription set and IP address can be configured. Another helper class (TAO_ECG_UDP_Receiver) acts as a supplier of events; it receives a callback when an event is available on an ACE_SOCK_Dgram, it demarshalls the event and pushes it to the EC. Two ACE_Event_Handler classes are provided that can forward the events to this Supplier: TAO_ECG_Mcast_EH can receive events from a multicast group; TAO_ECG_UDP_EH can receive events from a regular UDP socket.
