I found this sentence to be quite instructive.

\begin{quote}
In connection with link failures, we note that one could
pre-compute a good weight setting for each possible link
failure and have them ready for loading when needed.

That has some interesting operational issues, one would think, especially
in large networks that are dense partial meshes, with associated link
failure scenarios.
