In the @Home backbone, we used actual fiber miles (plus a small offset per hop
to break ties when a particular route had multiple paths with differing numbers
of routers). This, of course, just created a "base" configuration which could be
tweaked somewhat depending on what needed to happen to make the best use
of circuits.
