The ojective of this task is to launch NS3 network simulator with DCE support and to research dependency between TCP window size and TCP transfer speed.

5. Change TCP window size (to smaller or bigger value) and change link delay. Compare transfer speed and identify dependency between TCP window size, link delay and transfer speed
