[ENet-discuss] icmp/tracert/discovering network topology?

[Jay Sprenkle]

I would think the actual ping time would not be that useful. It would vary
considerably over time. What I was thinking was the length of the route in
routed hops, not physical distance, was what I needed to sort by. These
might measure roughly the same thing but physical organization only needs
one measurement.
