You have succeeded.  Your flow trace has the congestion window value 
listed explicitly.

Throughput, in its simplest form, can be computed as
	packets delivered / time

At time 1.13288 you have successfully delivered 2 packets.  I assume 
the sim started transmitting at time 1, so the time taken is 0.13288 
seconds.  2 / 0.13288 ==> 150.5 packets per second.  Multiply the 
packets per second by bytes per packet to get bytes per second.

There are more complex measures, but I'm not an expert in how to 
calculate them.  Try performing a search on the list archive for 
"goodput".

What do you mean by delay per flow?
