Purpose:
	demonstrate ns-2's capability in large-scale simulations

Topology: 
	~470 nodes and ~500 links simulated ISP topology
	with various bandwidth and delay 

Web Client:
	420 of them, all connected to one modem pool/node in a star graph

Web Server:
	40 of them 

Traffic:
	- one long-lasting tcp connection in blue
	- 200 web sessions issued by randomly selected web clients in 
	an exponential interval
	- web requests received by randomly selected web servers 
	- web servers reply with web object size in heavy-tailed distribution.

Memory Consumption:
	871MB to complete the simulation
