dosreduce creates a reduced network topology from
a larger inet topolgy based on intersection of attacker and
crosstraffic paths. The nodes and links that donot intersect
with the attack tree are pruned to create a reduced network
topology.

Input

dosreduce accepts the network topology (as a inet topology file),
the number of attackers, and active crosstraffic connections
at the command line.

Output

Based on the intersection of the attack tree and crosstraffic paths,
it outputs the attacker and victim nodes, and other required nodes and links
in the reduced topology.
