I definitely see the need to correlate request-response-pairs for UDP 
protocols but as UDP is *connectionless*, the term UDP connection sounds 
very strange to me. Maybe a general notion of request-response protocols 
could be established. Corresponding protocols could trigger general 
events. For some protocols there might be even a session concept.
