As Dirk already wrote, UDP is connectionless. Being like that, the 
application protocol (UDP payload) has to report connection closure. 
Have you bothered a) checking iPerf docs or b) reverse engineering its 
protocol with wireshark?

A quick look at a wireshark dump shows that this seems to be the case 
for iPerf over UDP, too. But also, the protocol seems to be at least a 
little different to the TCP version.
