The way from current packet drop to current total bandwidth need on
just a single path would appear to be non-trivial. The way from
current packet drop to future capacity need would seem rather more
complex.
Not that these are unworthy goals. But perhaps there are some closer
goals which might be more easily achieved first such as, as you say,
correlated QoS measures.
