# ./num-nodes/side-length/pkts-per-conn/num-conn 

# num-conn is either 3n (each node connects to 3 others) or nn (each
# node connects to every other node)

# traffic is generated to occur between 10 and 400 seconds; the
# `empty' 10 seconds in the beginning allows the routing protocols and
# location service etc. to initialize.

# first argument is the directory holding ns
