Re: More question on TCP packetSize_

[Gang Wu <wu15@ecn.purdue.edu>]

I think you can set whatever packet size you want (even down to 1, maybe 
0!!), since ns only uses this value to simulate, e.g., the simulation of
Xmission time of this packet. However, for tcp packets, it has no physical
meaning when you set the value less than its header size.  But, again,
this only violates the reality, but is allowed in the ns.
