I disagree, Gabriel -- since IS-IS doesn't do diversity routing, the
comparison is more interesting if babeld doesn't either.  I'd much rather
have two comparisons:

  - IS-IS compared to non-diversity Babel;
  - diversity Babel compared to non-diversity Babel.

We did some work on that with Gabriel a few years ago, and we found out
that the results are somewhat paradoxical: diversity Babel appears to beat
plain Babel in uncongested networks, but yields similar results in
congested ones.  My interpretation is that in a congested network packet
loss is a good indicator of interference, and therefore plain Babel
converges to a non-interfering set of routes without explicit interference
measurements.

The tests need repeating in a more formal setting, but they are extremely
time consuming, and more urgent stuff came up.
