Info on network simulation tools

[Paul Tsuchiya]

	To whomever reads these things.......

	     I am just starting some masters research on a distributed
	routing scheme for packet type networks and am in need of some
	network simulation tools that can run on unix.  Specifically, I
	am looking for tools that can create networks (from 20 to 2000+
	nodes), and that can run shortest path algorithms against which I 
	can compare my algorithms.
	     I would appreciate any referance to such tools or groups of
	people who do any kind of network simulation things.
