If you like to know the values in a steady state you sould run the simulation 
for at least several minutes. Especially in the first few seconds you can 
experience several strange effects. Something I often see is a storm of ARP 
packets at the beginning of a simulation because all stations start to 
communicate at about the same time. So, it is sometimes better to discard the 
results from the first seconds.
